Fishing for King (Chinook) Salmon

Last week, I mentioned that king (Chinook) salmon are the least abundant of the five Alaska salmon species, but their presence, or more accurately, absence, in the last several years has greatly impacted commercial, sport, and subsistence fishermen. Biologists quickly shut down fisheries in areas where they determine an inadequate number of king salmon have returned to spawn and maintain a healthy population. These closures not only affect sport anglers hoping to land a huge king, but they impact commercial and subsistence fishermen pursuing sockeye and other salmon species. Kings usually spawn in large river systems, the same systems sockeyes favor. When a fishery is closed to protect king salmon, gill-net fishermen and seiners are restricted from fishing in the area since their gear cannot differentiate between salmon species. Next week, I will go into more detail about the controversies swirling around king salmon, but this week I want to explain the different fisheries and even tell you a little about aquaculture for king salmon.

Commercial Fishing for King Salmon

 The king salmon return is small relative to other salmon species, but kings are worth a good deal per pound for commercial fishermen. In 2017 fishermen were paid an average of $5.86 per pound for kings. According to the state, commercial fishermen harvested 251,141 king salmon, worth $17.8 million in 2017.

The Alaska Department of Fish and Game (ADF&G) shut down commercial and sport fishing for kings in Southeastern Alaska on August 10th, 2017 when data indicated a record-low return of kings for the area. Commercial fishing for kings in Southeastern Alaska is primarily done by trolling. ADF&G opens the area to commercial trolling for kings in July and again in August, but with the poor return of king salmon to the area, ADF&G decided to cancel the August opening.

In other parts of Alaska, king salmon are not individually targeted but are caught in gill nets and purse seines with other salmon species. Even though kings return in relatively small numbers, there is an excellent market for kings because of their large size, rich flavor, and high levels of omega-3 fatty acids.]

I mentioned last week that 3% of all king salmon have white meat instead of red meat. Except for color, there is no difference in the chemical composition of the meat between white and red kings, but red-fleshed kings are more valuable because they look better to the consumer.

Sport and Subsistence Fishing for King Salmon

Anglers consider king salmon one of the ultimate game fish, and people flock to Alaska from all over the world for the thrill of fighting one of these monsters on a rod and reel or with fly gear. The main drawback for king salmon anglers is that relatively few rivers in the state have king salmon runs, and there are few areas on these rivers easily accessible to humans. Also, sockeyes and cohos spawn in the same rivers used by kings, so anglers targeting cohos and sockeyes also descend upon these same few fishing spots. As a result, king salmon fishing in Alaska is often called “combat fishing” with hundreds of anglers lining the banks of the river while sport fishing guides troll the river in front of them. Some folks enjoy the thrill of the combat-fishing drama, but this type of fishing cannot be considered relaxing and peaceful.

Combat fishing is famous on the Kenai and Russian Rivers on the Kenai Peninsula. Every summer, Central Peninsula General Hospital in Soldotna removes an average of 200 fishing lures from anglers who have been hooked by other fishermen. Etiquette rules exist for combat fishing, including yelling, “Fish on!” to let nearby anglers know you have a fish. Neighboring anglers are then supposed to reel in their lines and let you land your salmon as quickly as possible.

Trolling with rigged herring is the favorite method of fishing for kings in salt water. Most freshwater anglers use lures or salmon eggs. From 1989 to 2006, the annual Alaska sport-fish harvest of kings averaged 170,000 fish. Both a fishing license and a king salmon stamp are required to fish for kings, making it a lucrative fishery for the state.

An average of 167,000 king salmon are caught annually by subsistence fishermen. Subsistence fishermen can use a gill net, seine, long line or other methods defined by the Board of Fisheries.

Aquaculture for King Salmon

 While king salmon are not reared in pens in the United States, they are reared and sold in New Zealand and Chile. Half of the global production of king salmon comes from New Zealand, and half of New Zealand’s production is exported, mostly to Japan and other Pacific Rim countries, including Australia. Most farmed kings are raised until they weigh 6.6 to 8.8 lbs. (3-4 kg) before they are harvested.

King (Chinook) Salmon (Oncorhynchus tshawytscha)

King salmon, also called Chinook salmon (Oncorhynchus tshawytscha) are the largest Pacific salmon, and they are also the least abundant of the Pacific salmon species. Adult kings average 24 to 36 inches (61 to 91 cm) in length but may be as long as 58 inches (150 cm). They average 10 to 50 lbs. (4.5 to 22.7 kg) but sometimes grow much larger. The world record sport-caught king, caught on May 17th,1985 in the Kenai River in Alaska, weighed 92.25 lbs. (44.11 kg.), and the largest king salmon caught by a commercial fisherman weighed 126 lbs. (57 kg). This fish was caught near Rivers Inlet, British Columbia in the 1970s.

King salmon can be distinguished from other Pacific salmon species by the black spots present on their head and on both the upper and lower lobes of the tail and by their black gums. In their marine phase, kings are dark green to blue on the top of the head and back and silver to white on the sides, belly, and tail. When they return to fresh water to breed, they turn olive brown, red, or purple in color. Males are more brightly colored than females. In the ocean, kings are torpedo-shaped with a heavy mid-section and a blunt nose. During their breeding phase, males develop a hooked nose and enlarged teeth. Fry can be identified by well-developed parr marks extending below the lateral line. When they become smolt and are headed for the ocean, they have bright, silver sides, and the parr marks recede to above the lateral line.

In North America, king salmon range from Monterey Bay in California to the Chukchi Sea in Alaska. On the Asian coast, kings occur from the Anadyr River in Siberia to Hokkaido, Japan. In Alaska, they are most abundant in the Yukon, Kuskokwim, Nushagak, Susitna, Kenai, Copper, Alsek, Taku, and Susitna Rivers. Kings have been introduced to many areas, including the Great Lakes of North America, Patagonia, and New Zealand. King salmon are raised in pens in New Zealand and are an important export for the country.

King salmon spawn in fewer rivers than other Pacific salmon because they require larger, deeper rivers and spawn only in areas with good water flow through the gravel. They migrate from the ocean back to their birth streams in the winter and early spring, and while some enter fresh water as early as May, most enter streams in late June or early July. Most Alaska rivers receive only a single run of kings each year. Usually, those entering the streams first are the ones that will travel the furthest. Yukon River kings may travel more than 2000 miles (3219 km) to the headwaters of the Yukon River to spawn.

When a female king arrives in the spawning area, she selects a spot for her nest. She swims to the bottom of the stream, turns on her side and gives several powerful thrusts with her tail to remove gravel from the stream bottom. She continues to dig, resting occasionally, until she has a long, deep nest. While she is digging her nest, she drives off any other females that approach but pays little attention to the males. She is usually accompanied by a dominant male and one or two subordinate males. The dominant male, and occasionally one of the subordinate males, drive off any other male intruders. The males do not help with the nest digging, but the dominant male may court the female by resting beside her and quivering or by swimming over her and touching her dorsal fin with his body and fins.

When the nest is finished, the female drops into it followed by the dominant male and sometimes one or more of the subordinate males. The fish open their mouths, quiver, and release their eggs and sperm. The female then swims to the upstream end of the nest and begins digging a second nest, covering the eggs in the first nest with the gravel she unearths for the second nest. She continues digging four or five nests or more over the next several days and lays between 3,000 and 14,000 eggs. Even after all her eggs are laid, she continues digging in a haphazard manner until she weakens and dies. The male may mate with another female, but he also will soon die.

In Alaska, king salmon eggs hatch in the late winter or early spring, depending both on when they were laid and the temperature of the water. The hatchlings are called alevins, and they live in the gravel for several weeks, receiving nutrition from their attached yolk sac. Two to three weeks later, the young fry, as they are now called, wiggle up through the gravel and begin to feed on their own. Fry in fresh water feed on plankton and insects. Some kings, called “ocean-type,” migrate to saltwater during their first year. “Stream-type” kings remain in fresh water for one or even two years. In Alaska, most kings remain in fresh water one year and then migrate to the ocean as smolts the following spring.

In the ocean, king salmon eat herring, pilchard, sandlance, squid, crustaceans, and other organisms. They are voracious feeders, and they grow rapidly in the ocean, often doubling their weight in just one summer. Most king salmon have pink or red meat, but 3% of all kings have white meat. In Southeast Alaska, as many as 40% of the kings in some runs have white flesh. Biologists are unsure whether the variable meat color is due to genetics or to what the fish eat.

Kings become sexually mature anywhere from their second to their seventh year, so they vary greatly in size when they return to spawn. A mature three-year-old king, called a “jack,” would weigh less than four pounds (1.8 kg) while a mature seven-year-old would probably weigh more than fifty pounds (22.7 kg). Males mature earlier than females, so most jacks are males, and in many spawning runs, males outnumber females in all but the six-and-seven-year age groups.

King salmon are considered relatively uncommon but not rare in Alaska, but in some rivers their numbers have dropped drastically in the past few years. Over the next two weeks, I’ll write about the various fisheries for kings and the controversies swirling around them.

Author Platform

Last week in my Thanksgiving post, I mentioned working on my author platform. Since I am often asked how I sell my books, I decided to write a post about my author platform and how I promote (or how I should promote) my books.

I love to write and enjoy creating a fictional story, but the rest of my job as an author is not easy, and I’m not good at it. My latest novel, The Fisherman’s Daughter went on sale four weeks ago, and at first, sales were good, but lately, they have dwindled. I know sales have fallen because I have not been promoting the novel as I should. My excuse, and it is not a good one, is I’ve been exhausted. As we neared the end of the season at our lodge, I only had enough energy to work with nothing left over for writing or promotion.

According to my publisher, I should dedicate at least two hours a day to social media. Lately, I have fallen one hour and fifty-five minutes per day short of this goal. I also have not “advertised” my book in any other way. In today’s market where thousands of books are published every day, it is not easy for an author to find readers. There are, however, scores of “promoters” ready to tweet about an author’s book to the masses for a fee (and sometimes a hefty fee). I have fallen for some of these offers, and they did not work. If an author wants to find readers, she must reach out and approach them one at a time.

An author’s platform is a way an author attracts dedicated readers. A platform consists of a website, a blog with frequent posts, and a newsletter where an author can contact a prospective reader through his or her e-mail inbox. The platform also includes social media, such as an author’s page on Facebook, a presence on LinkedIn, an active Twitter account, a Pinterest board, Instagram, Google +, Goodreads, etc. The platform also includes non-internet activity such as book signings, speaking engagements, and other appearances where an author talks about her books.  The platform can also include many other things, but this gives you an idea of the basics.

I have a website and a blog, and I post frequently, I also have an e-mail newsletter. I am on social media, but I do not post as often as I should, and I am not active in the social media groups I have joined. I don’t usually have two hours a day to spend on social media, and if I did spend that much time on Facebook, LinkedIn, and Twitter, I’d never find time to write.

Unfortunately, while the number of brick and mortar bookstores decreases, the number of books being published increases. More than one million books are published in the U.S. each year, and it is impossible for a new author to get her book into a store without the backing of a large publishing agency. Most authors I know are not great at promoting themselves or their work. We want to write not sell.

I will keep working on my author platform, and maybe I’ll get better at self-promotion. My publisher is currently encouraging me to work on a webinar about how I became a published author. It’s a fun project, and I’m excited to work on it. I’m not sure how I will use it to sell books, but I’ll let you know when it’s done, so you can take a look at it and tell me what you think.

I’ll continue my salmon posts next week when I write about king salmon biology. My fish posts have been popular, and I love the opportunity to dive into each species and learn as much as I can about it. Learning about fish is so much more fun than selling books!

Please sign up for my newsletter so I can put another brick on my author platform!

Happy Thanksgiving

Happy Thanksgiving to my U. S. viewers, and thank you to everyone who reads my weekly blog. I think it’s great we have a holiday dedicated to reflecting on what is truly important to us and reminding us of all we have.

I’ve had a tough year, but instead of leaving me less thankful, this year has made me more thankful for all I have now and for all I’ve been blessed with in my life. Last year, my oldest brother died, and this year my other brother died, leaving me with no parents or siblings. The thought of being the last of my childhood family has knocked the wind out of me. Family memories from my childhood belong only to me now, and they are a burden that weighs heavily on me. I can no longer e-mail my brother and say, “Hey, remember the Thanksgiving when. . . ?

Holidays can be sad when a loved one has recently died, but I’m trying to focus on the good, and I have many wonderful people in my life for which I am very thankful. This year, in particular, I am taking stock of my loved ones.

I have also had a rough year health-wise, but I am slowly recovering, and I made it through our busy season, so now I can rest. My illness has made me think about people who are disabled with no hope of recovery, and my heart goes out to them. Not being able physically to do what you want is tough, and I am thankful I will recover my strength within a few months.

Writing brings me joy and gets my creative juices flowing, but lately, I have been too tired to write. Our lodge is now closed for the year, though, and I am looking forward to again tackling my writing projects. I’ve started my next novel and hope to edit my wildlife book and get it ready to publish.

Working on my author platform is necessary if I ever want to make a living as an author, but I have put little effort into promotion lately. I plan to spend a great deal of time working on my author platform over the next several weeks.

Life in the wilderness can be hard. We must do everything ourselves. We can’t call a mechanic if something breaks or hire a crew to build a new cabin. It’s up to my husband and me to do these jobs, and sometimes I yearn for an easier life. Then, I look around me at the beauty of the ocean and the mountains, and I pinch myself. I am the luckiest person in the world to live in such a beautiful place, and I am very thankful. Where else could I look out the window and see a beautiful fox sitting in the backyard?

I am thankful for all of you who have read my books, my mystery newsletters, and my blog posts. The number of people who visit my website each day has slowly increased over time, and the number of subscribers to my newsletter continues to grow. Whenever I receive a notice saying someone new has signed up for my newsletter, I cheer. I value each of my subscribers, and I work hard to write interesting newsletters for them each month.

Thanksgiving is a wonderful time to reflect, and I only need to watch the news to realize how fortunate I am to live in a country where freedom is a right, not a dream.

Happy Thanksgiving to all of you!

Sockeye Salmon and Humans

Humans prize sockeyes for their firm, beautiful meat. A strong or weak sockeye run can mean the difference between fortune and poverty for commercial fishermen, and sport and subsistence anglers wait eagerly for the sockeyes to return each summer. Not only are sockeyes the ultimate fish to smoke, dry, or freeze, but they are good fighters and fun to catch.

As I mentioned last week, the complex life cycle of a sockeye salmon requires an extensive river/lake system. Sockeyes spawn in the stream or river, and then the fry move into the lake where they feed and grow for one or more years before heading out to sea. This life cycle works best when man does not interfere by building dams, logging, digging mines or developing land near critical salmon spawning and rearing habitat. Unfortunately for the salmon of Bristol Bay, the richest sockeye spawning grounds in the world, the rivers where sockeyes spawn are near one of the largest copper ore deposits in the world. For the past several years, Alaskans have been arguing loudly about the proposed Pebble Mine in Bristol Bay. After I describe the commercial and sport fisheries for sockeyes, I will explain the Pebble Mine debate in more detail.

Commercial Sockeye Fishery

 Sockeyes are the most valuable salmon for commercial fishermen. There aren’t as many sockeyes as pink salmon, but sockeyes are worth more per pound than pinks because their meat is firmer, they freeze better, and they have a richer flavor than other species of salmon. Bristol Bay in southwestern Alaska has the largest commercial sockeye fishery in the world. On average, fishermen catch ten to thirty million sockeyes each year in the region during a short, intense fishery lasting only a few weeks. In 2017, 59 million sockeyes were caught in Bristol Bay, and processors paid fishermen $1.13 per pound. The total sockeye harvest for the state in 2017 was valued at $326 million.

Certain regions of Bristol Bay are particularly productive. In 2017, commercial fishermen in the Nushagak region caught over one million salmon on two separate days. On July 3rd, during a storm and in heavy seas, fishermen landed 1.5 million sockeyes, and several fishing boats sank or became grounded when fishermen battled stormy seas while heavily loaded with fish.

Sport and Subsistence Fisheries

 Sockeyes are important to the economy of Alaska, not only because of the commercial fishery but also due to a growing sport fishery that brings many visitors to the state. One of the most important fisheries to the residents of Alaska, though, is the subsistence harvest. Most subsistence fishing is done with a gillnet.

Sport fishing for sockeyes is an art. Sockeyes eat plankton, so unlike cohos, pink salmon, and king salmon, sockeyes do not aggressively chase a lure. Fishing experts suggest the best way to hook a sockeye is by using a bare hook or a hook with colored yarn tied to it. The angler then catches the fish by either accidentally hooking it in its mouth or by aggravating the salmon with continual casts until the fish snaps at the hook. Once the fish is on the line, it is a strong fighter

 Status and Trends

While salmon stocks in the lower 48 have declined significantly over the past few decades, sockeye salmon stocks in Alaska are doing well. Due to their economic importance, sockeyes are carefully managed by the Alaska Department of Fish and Game, but in recent years, the proposed Pebble Mine project near Bristol Bay has concerned many Alaskans about the future of the largest sockeye salmon run in the world.

The Pebble Mine is the name of a mineral exploration project hoping to gain the rights to mine a huge copper, gold, and molybdenum mineral deposit in the Bristol Bay region near Lake Iliamna and Lake Clark. This deposit is estimated to be the second largest of its type in the world. Those who support the mine say it will create jobs, provide tax revenue to the state of Alaska, and reduce American dependence on foreign sources of these minerals. Those opposed to the mine, claim it will pollute the Bristol Bay watershed, possibly destroying valuable fish stocks, including sockeye salmon. If that happens, the strong fishing economy already present in the region could collapse, wiping out fishing jobs and income.

Nearly every copper mine in the world has polluted the environment around it by releasing water high in acids and contaminants. Plans for the open-pit Pebble Mine propose to impound contaminated water, waste rock, and mine tailings behind several earthen dams at the mine site. This mine would be situated upstream from the Kvijack River, the river with the single largest sockeye salmon run in the world.

The controversy over the Pebble Mine has been a major issue in Alaska since the mid-2000s. In April 2009, a Native delegation from the Bristol Bay region told the mining company behind the Pebble project that the Bristol Bay watershed was no place for an open-pit mine. The mine was put on hold in 2013 after the loss of funding partners, but it has recently gained the interest of other investors and is now back in the news.

I will be honest; I am opposed to the Pebble Mine, and support for the mine is low in Alaska. Anything that could destroy the pristine environment where millions of sockeye and other salmon return each year to spawn should not, and I hope will not be allowed.

Do you have an opinion about the Pebble Mine? I’d love to hear it!

Sockeye (Red) Salmon (Oncorhynchus nerka)

Sockeye salmon also called red salmon and sometimes blueback salmon, are larger than pink salmon but average smaller in size than other Pacific Salmon species. Sockeyes measure between 18 and 31 inches (45.7-78.7 cm) in length and weigh between 4 to 15 pounds (1.8-6.8 kg). In their marine phase, sockeyes have iridescent silver sides, a white belly, and a metallic green-blue back. Due to this marine coloration, sockeyes are sometimes called blueback salmon. While they can have fine, black speckles on their backs, they lack the large spots found on other species of Pacific Salmon. The flesh of a sockeye in the marine phase is bright orange and firm. This beautiful, firm flesh with its rich flavor makes sockeyes highly prized and a culinary favorite.

When sockeyes return to their natal streams to spawn, their bodies turn bright red, and their heads become green. They are called red salmon because of this spawning coloration. In addition to changing color when they return to spawn, males develop a humped back, and hooked jaws called a kype. Breeding females are paler in color than males.

Unlike pinks, chums, and cohos that can spawn close to the mouths of small streams, sockeye salmon usually spawn in large, complex river/lake systems. Most sockeyes spawn either in streams connected to lakes or along the lakeshore in areas of upwelling. Because a sockeye requires unimpeded access to a lake to complete its life cycle, it is susceptible to habitat manipulation or degradation. Not only man but also beavers can alter a river system by building dams, effectively blocking a river or stream and denying salmon access to the lake.

The natural range for sockeyes is from the Klamath River in California and Oregon north to Point Hope in Alaska. In the western Pacific, sockeyes range from the Anadyr River in Siberia south to Hokkaido, Japan. Sockeyes are most numerous in the Fraser River system in British Columbia and the Bristol Bay system, including the Kvichak, Naknek, Ugashik, Egegik, and Nushagak rivers. Some populations of sockeyes do not migrate to the ocean but spend their entire lives in freshwater. These landlocked salmon are called kokanee salmon. Kokanees are found from Siberia to Japan on the Asian side of the Pacific and In North America from the Kenai Peninsula to the Deschutes River in Oregon. Kokanees have been widely introduced to lakes in the U.S., including the Great Lakes.

In Alaska, sockeye salmon return from the ocean to spawn from July to October. Like other Pacific Salmon species, sockeyes spawn in the streams where they were born. Some sockeyes spawn in streams not connected to lakes and others spawn near the lakeshore, but most spawn in streams attached to a lake. A female digs a nest in the stream bottom by giving several, powerful strokes of her tail. Once she finishes digging the nest, she rests while a dominant male courts her by nudging her side with his snout and then coming to rest beside her and quivering. The female then drops into the nest, and the male follows, stopping beside her. Both fish arch their bodies, open their mouths and quiver, releasing their eggs and sperm. Other males may also enter the nest and release sperm. The female will continue to dig nests until she has deposited all her eggs. She usually digs three to five nests over the course of three to five days, and she may breed with several dominant males. A female deposits between 500 to 1,000 eggs in a nest and lays a total of 2,500 to 4,300 eggs. A male sockeye may breed with several females, and both male and female sockeyes die within a few weeks after spawning.

Sockeye eggs hatch in the winter, and the young alevins remain in the gravel, gaining nutrition from their yolk sacs until spring when they emerge into the stream. At this stage of their lives, the young sockeyes are called fry and have dark, short, oval parr marks on their sides. Fry move out of the stream and into the lake where they spend one to three years in fresh water, feeding on zooplankton and small crustaceans. As they prepare to leave the lake, sockeyes lose their parr marks and turn silvery. They are now called smolts. Smolts weight only a few ounces when they enter the ocean, but they begin to grow quickly, mostly feeding on plankton, insects, and small crustaceans. A sockeye’s beautiful orange flesh comes from eating plankton and krill in the ocean.

Sockeyes spend one to four years in the ocean where they travel nearly continuously, covering as many as 2300 miles (3700 km) in one year. As it begins the return trip to its spawning stream, a mature sockeye swims even faster, covering 28 to 35 miles (45-56 km) per day during its last two months at sea. Sockeyes are prey for nearly every animal they encounter that is bigger than they are, and they are a valuable species for commercial fishermen.

________________________________________________________________________

Next week, I will cover the commercial and sport fishery for sockeyes as well as the status of sockeye populations and threats to their survival, including the controversial proposed Pebble Mine in Bristol Bay, Alaska.

I would love to hear your opinions and ideas about the Pebble Mine as well as about anything else related to salmon conservation or any of my other posts.

Commercial and Sport Fishing for Coho (Silver) Salmon

Last week, I wrote about the life cycle of a coho salmon, and I mentioned cohos are the most aggressive species of Pacific Salmon. Their aggressive nature makes them a favorite target for anglers. Cohos can be caught in the ocean and their spawning streams. They hit a lure or a fly hard and are tenacious fighters, often leaping out of the water and running fast both away and toward the fisherman. Coho salmon are also an important commercial species, but there are not nearly as many cohos as there are pink, chum, or red salmon, so cohos are not as economically valuable to commercial fishermen as these other Pacific Salmon species. In this post, I will cover both the commercial and sport fisheries for coho salmon, and I will discuss the current status, threats, and trends of cohos in their native range.

Commercial Fishery for Cohos in Alaska

 In most of the state, commercial fishermen catch coho salmon together with other salmon species by purse seining and gill netting. In Southeast Alaska, though, the majority of coho salmon are caught by the commercial troll fishery.[9] In 2017, commercial salmon fishermen in Alaska harvested nearly 225 million Pacific Salmon. Five million coho accounted for 2% of the harvest, but due to their large size and a price of nearly $1.20 per pound, the commercial coho catch was worth 38 million dollars, or 6% of the total salmon harvest value.[10]

Sport Fishery for Cohos in Alaska

The coho salmon is one of the most sought-after game fish in Alaska, and since the decline in king salmon numbers over the past few years, the sport fishery for cohos has become even more popular. Cohos are targeted by anglers in salt and fresh water from July through September in Alaska, and sport anglers catch nearly 1.5 million cohos every year in the state.[9]

In salt water, cohos are mostly caught by trolling or mooching. Herring is a popular bait, and any jig that looks like a small fish works well. Cohos are not particular about the bait or the jig as long as the angler keeps the jig active. The biggest challenge of catching cohos in the ocean is finding them. They may be at any depth from the surface to eighty feet or deeper.

Cohos are more finicky once they enter their spawning stream when their bodies change shape and color, and they stop eating. They will still aggressively hit a lure or a fly even after they gain their spawning colors, but they often become shy of lures, especially on a sunny day. Popular freshwater lures for spin fishing include Pixee spoons, golf tees, and spinners.

Status and Threats for Cohos

 Many coho salmon populations in California and the Pacific Northwest are threatened or endangered, but coho populations in Alaska are healthy.[9] In the southern part of their range on the west coast of the United States, humans have altered much of the coho’s habitat by urban development, constructing dams, diverting streams and rivers for agriculture, recreation, mining, logging, and other human-related activities. Studies show that in most western states, 80 to 90 percent of the historic riparian habitat has been destroyed, and 53 percent of the wetlands in the lower 48 have been eliminated. California has lost 91% of its wetland habitat, and wetlands in Oregon and Washington have been diminished by one third.[9] How can coho salmon with their complex lifecycle in fresh and salt water possibly thrive when much of the habitat they need to survive is gone?

Throughout their range, including Alaska, coho salmon will likely be impacted by warming ocean temperatures.

Coho or Silver Salmon (Oncorhynchus kisutch)

Coho salmon, often called silver salmon due to their beautiful bright chrome color, are the most aggressive of the Pacific Salmon species. There aren’t as many cohos as there are pink salmon, chum salmon, or sockeye salmon, but coho salmon manage to spawn in tributaries and small headwaters inaccessible to other salmon species. A Coho can leap vertically six feet (1.8 m) to overcome obstacles such as rapids or waterfalls on its return journey to its spawning stream, and cohos usually migrate to their spawning streams later than other salmon species at a time when fall floods allow them to access areas not available during lower water levels.  Even young cohos are aggressive, and they often eat the young of other salmon species. This aggressive nature of coho salmon makes them excellent fighters on a rod and reel and an important species for the sportfishing industry in Alaska.

Range

The natural range of coho salmon is from Monterey Bay, California north to Point Hope, Alaska, west across the Bering Sea to the Anadyr River in Siberia, and south along the coast of Asia to Japan. Cohos have been introduced to the Great Lakes and other lakes in the Continental U.S. Cohos spawn in ponds, lakes, and pools within streams and rivers.

Coho adults usually weigh between 8 and 12 lbs. (3.6-5.4 kg) and range from 24 to 30 inches (61-72 cm) in length, but fish weighing up to 31 lbs. (14.1 kg) have been caught. During their marine phase, adults are bright silver and have small, black dots on the back and the upper lobe of the tail fin. In their marine phase, cohos look very similar to king (Chinook) salmon, but king salmon have spots on both lobes of the tail, while cohos only have spots on the upper lobe. Another way to distinguish the two species is cohos have white gums, while king salmon have black gums.

When cohos return to freshwater to spawn, males turn dark to bright green on the head and back, bright red on the sides, and dark on the belly. Breeding females are not as brightly colored as males. Spawning males develop a hooked jaw called a kype.

Life Cycle

In Alaska, coho salmon return to their spawning streams from July to November, usually during periods of heavy rain and high runoff. On Kodiak, most cohos return from late August through October. A female coho selects a suitable spot and then begins to dig a nest, or redd. She turns on her side and gives several powerful flips of her tail to remove silt and other debris and then continues to dig for two to five minutes until she has a shallow nest. While she is digging her nest, she aggressively drives away other females. Meanwhile, a male coho stays near the female while she digs the nest, occasionally swimming close to her. He may also stop beside her and quiver, swim over her and touch her dorsal fin, or nudge her side with his snout. When the female has finished excavating the nest, she drops into the deepest part of the depression, and the male immediately joins her. The two fish remain side by side in the nest while they open their mouths, quiver, and release eggs and sperm. The female then moves upstream and begins digging a new nest, covering the eggs in the first nest with the gravel she dislodges from the second nest. Nest digging and spawning may continue at intervals over the next several days, until the female deposits all her eggs. The male might then leave and seek another female, but the female will continue the digging process until she grows weak and dies.

A female coho lays between 2,400 and 4,500 eggs. The eggs develop over the winter and hatch in the early spring. The alevin, with the yolk sac attached, remains in the gravel until May or June before emerging. Young silver salmon fry usually spend between one and three winters in fresh water, but some spend as many as five years in a lake before migrating to the ocean. Young silver salmon in Karluk Lake on Kodiak Island often stay two, three, or even four years in fresh water before migrating to sea. The length of time spent at sea also varies for coho salmon. Some males, called jacks, mature and return after only six months at sea, but most cohos remain in the ocean for 18 months to three years and return as full-size adults.

Prey and Predators

Cohos are aggressive feeders. In freshwater, they eat a wide range of aquatic insects and plankton. They also eat salmon eggs, and as they grow, the fry also consume smaller fry. In the ocean, cohos eat herring, sand lance, other fish, and squid.

Young coho are eaten by birds, larger fish, and a variety of other predators. Killer whales, sharks, sea lions, seals, bears, humans, and other land mammals prey on adult cohos.

Next week, I will cover commercial and sport fisheries for cohos as well as threats to coho salmon populations.

Chum Salmon (Oncorhynchus keta)


Chum salmon (Oncorhynchus keta) are the most widely distributed Pacific Salmon species and can be found throughout Alaska. They range along the east and west coasts of the North Pacific Ocean, from the Mackenzie and Anderson Rivers in Canada to the Lena River in Russia.

Chums are often called dog salmon, but experts disagree about the origin of this nickname. Some believe chums are called dogs because, in the Arctic, Northwestern, and Interior parts of Alaska, chums were and still are traditionally dried and used as a winter food supply for both humans and dogs. Others argue they are called dog salmon because of the enlarged “canine” teeth the males develop during the spawning season.

Chum salmon are the second-largest Pacific Salmon species. Only Chinook (King Salmon) grow bigger. An average adult chum salmon weighs between 8 and 15 lbs. (3.6 to 6.8 kg), but they can grow as large as 45lbs. (20 kg). During their marine phase, chums are dark metallic blue on the back and silver on the sides and belly. Tiny dark specks may be present, but chums do not have large spots like those on Chinook, coho, and pink salmon. The tail of a chum salmon is highly forked, lacks spots, and has silver streaks along the fin rays.

When chums enter fresh water on the return to their spawning streams, males darken to what is often described as a calico pattern. They turn a dark olive brown and have red to purple, wavy, vertical stripes. They also develop hooked jaws called a kype lined with large, sharp teeth. Females turn brown and have a dark, thick, horizontal bar running along the lateral line. Females also develop a hooked jaw with large teeth, but the jaw is less pronounced than it is in males.

There are two, distinct races of chum salmon that spawn at different times. Summer chums spawn in early to mid-summer, and fall chums, as their name suggests, spawn later in the autumn. Chum salmon usually spawn at the mouth or in the lower sections of a stream or river, but in large river systems, they may travel as far as 2000 miles (3219 km) upriver to spawn.

When spawning, a female chum digs a nest in the gravel of the streambed. She then deposits her eggs in the nest while one or more males release sperm to fertilize the eggs. The female may dig more nests upstream from the first nest, depositing her eggs in the nests until her eggs are gone. A group of nests is called a redd, and a female guards her redd until she becomes weak and dies.

Chum salmon eggs hatch after three to four months. The alevin that emerges from the egg remains in the gravel, receiving nutrients from its yolk sac for 60 to 90 days. When it emerges, a chum salmon fry is dark greenish-brown on the back and iridescent green below the lateral line. It also has 8-12 vertical, spaced parr marks on the upper half of its body, not extending below the lateral line.

Fry begin migrating downstream to the ocean within a few days to a few weeks after emergence when they are only one to two inches long. Young chums spend several months near shore before traveling to the open ocean. They stay in the ocean three to four years where they grow to a size of 8 to 15 lbs. (3.6-6.8 kg) or larger. They grow the fastest during their last year in the ocean. Like other Pacific Salmon, chums return to spawn in the stream or river where they were born, and after spawning, they die.

Juvenile chum salmon eat crustaceans, insects, and young herring. Adults feed on copepods, tunicates, mollusks, and fish. When adults return to fresh water to spawn, they stop eating, and their digestive tract deteriorates.

Chum salmon rank second to pink salmon in average annual catch in Alaska’s commercial fishery. Chum-salmon meat is commercially the least valued of the salmon species, and commercial fishermen are paid less or the same for chums as they are for pink salmon. Chum-salmon eggs, though, are the largest and most valuable of any salmon eggs and are sold in Japan as ikura salmon caviar. Chums are not usually targeted by sports anglers because they rarely aggressively attack a lure.

Pre-Order The Fisherman’s Daughter

 

I am thrilled to announce the e-book of my new novel, The Fisherman’s Daughter is now available for pre-order on Amazon, Barnes and Noble, and other online booksellers. Here is a short synopsis of the novel:

Seventeen-year-old Deanna Kerr fights to start her outboard engine as storm-tossed waves fill her boat with water. Panicked and crying, relief spreads through Deanna when a boat approaches her. She believes she is about to be rescued. Four months later, Deanna’s bones are found in a pile of kelp on the beach. Her ankles are wired together, and her skull crushed.

Alaska State Trooper Sergeant Dan Patterson fears a serial killer is stalking women on Kodiak. Including Deanna Kerr, three women have been murdered on the island in the past six months.  When a park ranger discovers the body of a fourth woman dumped in the park in the middle of a blizzard, Patterson contacts the FBI and requests their assistance.

FBI, Special Agent Nick Morgan has been to Kodiak before on another case, and he volunteers to return to the fascinating island and its unique, independent people. He knows he also accepted this assignment because he hopes to see Dr. Jane Marcus, a woman he met on his previous trip to the island and hasn’t been able to stop thinking about since then.

Morgan flies into Kodiak on an icy, December day to offer his assistance to the investigation. Only 13,500 people live on Kodiak Island, but Morgan soon realizes the list of suspects for these crimes is long. Could the killer be the crab boat captain who knew Deanna Kerr and was the last person seen with one of the other victims, or is the murderer one of the coaches at the high school or the strange assistant coach who seems to have an unhealthy relationship with children? The killer could also be someone related to one of the victims. Morgan believes the killer is a person the victims had no reason to fear and he thinks they willingly met with him. As the investigation proceeds, Patterson begins to worry the murderer could be a police officer or a trooper and may even be one of the members of his task force.

When the murderer strikes again, tensions escalate, and Patterson and Morgan know they must catch this monster before another woman dies or before the killer leaves the island and begins preying on women somewhere else.

The Fisherman’s Daughter will be released as an e-book on October 17th, and the print version will be released on November 1st. If you are planning to buy an e-book of The Fisherman’s Daughter, it will help boost the book’s ratings if you pre-order it. As always thank you for your support!
