Myths and realities of Far Eastern salmon and its relatives

Far Eastern salmon: fish from a region of untouched wilderness

Most salmon are migratory fish, which means that they are born in rivers, migrate to the ocean as young fish, where they live and feed, but return back to the river to spawn.
This is their life cycle: salmon breed only in fresh waters, and after spawning almost all die. But it is important for the fish to return exactly to the river in which it was born. It is still unknown exactly how the fish finds its way home: most likely, it is helped by its sense of smell and the memory of the Earth’s magnetic field in the place where it first entered the ocean. But the important thing is that the Far Eastern salmon is a child of the wild, which lives in harmony with the water element and gives us the opportunity to draw strength and energy from the ocean. Wild Far Eastern salmon: pink salmon, chum salmon, coho salmon, sockeye salmon, masu salmon, chinook salmon, char, taimen, lenok, whitefish

Origin and description

Salmon belong to a group that appeared quite a long time ago: according to some sources, its ancestors originated on Earth millions of years ago. Although they took their current form much later. It is believed that about fifty species belong to this family.

The length of salmon can even reach up to two meters. At the same time, there are also species that are quite small - only twenty or thirty centimeters. The weight of this fish is also a serious indicator. For example, types of salmon such as taimen or salmon reach seventy kilograms.

Their structure is as close as possible to herring-shaped ones. The body, compressed laterally, is distinguished by the presence of a lateral line. Multi-rayed fins are located on the middle part of the belly, while there are no spiny rays on the pectoral fins. Characteristics of salmon are the spots that are its “calling card”. After all, even the name itself, which has an Indo-European root, means “to become covered in spots.”

Benefit for health

Wild Far Eastern salmon lives in the natural conditions of the Pacific Ocean and the purest deep rivers, feeding on phytoplankton and then krill and without encountering civilization or humans. Salmon meat is rich in the powerful natural antioxidant astaxanthin and Omega-3 fatty amino acids, which slow down the aging process. In addition, fatty acids have a beneficial effect on brain cells, improving memory and attention. Experiments on mice indicate that including large amounts of Omega-3 in the diet can increase life expectancy by a third.

In addition, salmon meat is rich in potassium, phosphorus, chromium, vitamins B1 and PP. Phosphorus is responsible for the strength of bones and teeth, energy synthesis, and is also involved in the construction of cells, so salmon is especially necessary for a growing organism. Potassium helps fight fatigue and depression.

Eating salmon

• Strengthens immunity
• Stimulates metabolism
• Reduces cholesterol levels
• Fights inflammatory processes
• Stimulates brain function
• It prevents cardiovascular diseases.

For obvious reasons, wild fish caught in the ocean, at the most remote end of our country, cannot be delivered fresh to the buyer. It is supplied to stores frozen, smoked, salted and in canned form. Frozen and canned fish retain as much nutrients as possible; however, it is best to choose fish processed directly at sea immediately after catching - this way you can be sure of the quality of the product.

The most recognizable salmon

Undoubtedly, everyone recognizes pink salmon, even those who have never seen them. The famous hump on its back, which gives it its name, develops in males during migration to spawning grounds.

The largest salmon

Taimen is the largest representative of the salmon family. It reaches 1.5-2 meters in length and weighs from 60 to 80 kilograms.

The most numerous salmon

And this is pink salmon again: this is the most common species among Pacific salmon, both in terms of population size and in terms of fishing volumes.

The most dietary salmon

Chum salmon is the lowest-calorie salmon fish: it contains 127 kcal per 100 g. For other representatives of wild salmon, the average calorie content of meat is 160 kcal per 100 g. But artificially grown salmon, deprived of the opportunity to swim huge distances every day in search of food, is much more fatty – up to 200 kcal.

The most unusual salmon

This is definitely a char: it is caught only three months a year. It has gray meat, an incredible, incomparable taste, and, of course, the benefits of a truly natural product.

The most delicious salmon

Many connoisseurs agree that the chinook salmon has the most delicious meat among salmon. For this, the Japanese call it the “Prince of Salmon”, and the Americans call it “King Salmon”.

You can argue about tastes endlessly, but only one thing is clear: natural fish grown in the wild is the most delicious and healthy. This will be confirmed by anyone who has ever compared the taste of wild Far Eastern salmon and artificially farmed salmon or trout.

Trout

This fish of the salmon family is found in Lakes Onega, Lake Ladoga and other reservoirs of Karelia and the Kola Peninsula; it can also be seen in the basins of the Baltic and White Seas. Trout comes in several varieties:

1. Scottish.
2. Alpine.
3. European.
4. American.
5. River.
6. Ozernaya.
7. Rainbow.

Freshwater fish of the salmon family prefer cold reservoirs with clean and clear water. Lake trout are diverse in color and lifestyle. Representatives of this species of salmon have long been objects of artificial breeding both for hunting and for food. Brook trout is often called pied trout because of its bright color; lake trout has a second name - brown trout.

The pestle grows to a size of 25 cm and weighs up to 500 g. It prefers fast and cold rivers. Spawns in autumn or winter. Lake trout are golden in color with numerous black spots. This species of salmon is much larger than river trout. They reach a length of up to 50 cm and weigh up to 1.5 kg (although some individuals grow up to 8 kg in weight). Lake trout spawns from September to January, depending on the reservoir, either on rivers with a pebble bottom, or in lakes, in places where springs flow. Trout feed on small fish, insects and larvae, and invertebrate animals. Trout meat is darker in appearance, but just as tasty and tender as that of other salmonids, and in addition, it is also healthy.

Valuable and tasty meat and red caviar have made the salmon family a popular commercial species. Illegal fishing of this fish is reaching large scales. As a result, many species of salmon are listed in the Red Book and are under state protection.

Use the “Catch and Release” principle!

“Game fish are too valuable to be caught only once.” — Lee Fulf, famous American fly fisherman, 1939.

This is what Atlantic salmon looks like, salmon (lat. Salmo Salar) that has just entered the river from the sea. The most valuable commercial fish. Catch strictly according to issued licenses. At this stage it has exceptional gastronomic qualities. Specimens up to 30 kg in size enter the rivers of the Kola Peninsula.

This is what salmon look like when they have spent some time in a river or lake and are ripe for spawning. (Male above, female below). If the fish came in in May-June, then it acquires this color by August. At this stage, the salmon is “in fighting shape” and catching it is a thrill. Taste qualities sharply decrease after the marine form. It is recommended to release such fish into the river.

This is what salmon look like (male above, female below) having already entered the spawning stage, usually in September-October, they are about to lay eggs or are already guarding the hatching larvae in the nest. Such fish must be released without injuring them.

This is what salmon (kelt, valchak) looks like in the spring, but after the autumn spawning. This fish is trying to get back into the sea to recover from exhaustion. To confiscate such a fish, which has actually conquered all stages of river obstacles, is simply moral blasphemy.

A young salmon lives in the river for several years. Outwardly, it resembles the brook vorelle, but differs from the latter in the presence of vertical blue spots. If accidentally caught, it should be immediately released into the wild. The state pays a lot of money for the artificial cultivation of salmon.

Brown trout, brook trout, sea trout fish of the same species Brown Trout (lat. Salmo Trutta). Typically, local residents call trout fish up to 1 kg that live in streams and lakes. Specimens larger than 1 kg are called brown trout. Brown trout living in the sea or deep clear lake wear a silver outfit, and fish living in a lake or river with peaty water are brown. They have residential, walk-through and semi-pass-through forms. Sometimes these species live together in the same body of water. Reaches a size of 15 kg. According to the rules of amateur fishing, specimens over 40 cm long (from 1 kg) are suitable for seizure.

Difference between Atlantic salmon and sea trout. I - Atlantic salmon, II - sea trout. Salmon differs from large sea trout in having a more streamlined shape, a concave tail, a thinner tail wrist, and a short upper jaw (no longer than the back of the eye). Salmon have almost no spots below the lateral line. Salmon have 10-15 (usually 11-13) rows of scales between the adipose fin and the lateral line; trout have 13-16.

Grayling (lat. Thymallus thymallus). Inhabits many rivers of the Kola Peninsula. The most delicate fish. Requires careful handling. When catching a small specimen, you should remove the hook from the mouth without removing the fish from the water. Grows up to 3 kg.

As a result of an unsuccessful acclimatization experiment, this Far Eastern fish is seriously competing with Atlantic salmon on spawning grounds. In recent years, it has become a trash fish and is recommended for mandatory removal when caught. Kola pink salmon meat has low culinary appeal compared to salmon. Grows up to 5 kg.

Arctic char (lat. Salvelinus alpinus), listed in the Red Book. In different habitats of the Kola, these fish have a wide variety of colors, reminiscent of the variegation of trout. It has a pass-through and semi-pass-through shape. If caught, it should be released into the wild.

Whitefish (lat. Coregonus). Found in the sea, lakes and rivers of the Kola Peninsula. The meat is tender and tasty. Grows up to 5 kg.

Burbot (lat. Lota lota). Contrary to all claims, burbot is a northern fish. On the Kola Peninsula it grows up to 10 kg in size.

Of the fish familiar to the Middle Zone, we can mention perch and pike, which are found in abundance on the Kola. Roach and ide are found in some lakes. To be completely honest, we should also indicate the carp and sturgeon that live only in one place on the Kola Peninsula - this is the confluence of the Kola Nuclear Power Plant canal into Lake Imandra.

Salmon fish , also known as red fish, are a special species, a special caste of fish. There are carp fish, there are perch, pike, catfish, cod, sturgeon and many others. Of course, each type of fish, each family, is famous in its own way, but it is salmon and its family that rightfully occupy a special place among aquatic inhabitants. This is a special, royal status! In this material I will list and briefly describe the most popular fish from the salmon family.

Salmon and Trout are collective names that often refer to different species of fish of this family.

Salmon fish can be sedentary, permanently living in rivers, or anadromous, permanently living in the sea and going to rivers to spawn. Salmon are distributed in the middle and northern latitudes of the northern hemisphere, in the waters of the Atlantic and Pacific Oceans (Noble Atlantic and Pacific Far Eastern salmon).

Salmon are valuable as commercial fish for catching and artificial breeding. The red fish itself is valuable, as is the red caviar.

Salmon is a very strong fish. When going to spawn, salmon overcome rapids and even small waterfalls. So, even when caught with amateur gear, the resistance is fabulous.

The salmon family is divided into subfamilies: Salmonidae; Whitefish; Graylings.

Trout is a common, collective name for more than two dozen salmon fish. For example, these are: brook trout; lake trout (aka brown trout); marbled trout; Caucasian trout; Dolly Varden; mykizha; Clark's salmon and many others. The difficulty of classifying trout and salmon fish in general lies in the fact that sedentary forms easily adapt to life in the sea and become migratory, and vice versa.

Salmon – also called Atlantic salmon (anadromous) or Lake salmon (resident). It lives in the Atlantic Ocean and enters the rivers that flow into it. The lake form lives in lakes in northwestern Russia and in the Scandinavian countries.

Taimen is the largest species of salmon fish. Taimen is a predominantly sedentary form of salmon that lives in rivers and lakes from the Urals to the Far East. There is also a passing one, Sakhalin taimen Taimen is a very coveted trophy for a spinner! Particularly enthusiastic taimen fishermen navigate the most difficult routes along the wild taiga rivers of Siberia, fly in helicopters, and overcome forest debris in order to catch large taimen.

Pink salmon is one of the anadromous Pacific salmon. Pink salmon are not large compared to other Pacific salmon, but they are the most numerous. During the spawning period, when entering the river, the male pink salmon grows a characteristic beak to drive away other fish from the spawning nest, as well as a hump (apparently, for greater menacingness). Hence the name.

Lenok is a common sedentary species of salmon. Inhabits rivers and lakes from the Urals to the Far East. Relatively small salmon, they do not grow more than 6 kg.

Chum salmon is one of the most common salmon species, with the largest distribution area. It enters the rivers of the Arctic Ocean and the Pacific Ocean, both within Asia and North America.

Sockeye salmon is a species very close to Chum salmon. Sockeye salmon can be unmistakably recognized by the very bright red color of its meat.

Coho salmon is a fairly large Pacific salmon (up to 1m in length and 15kg in weight). It is distinguished by its silvery scales. More common along the American Pacific coast than off the coast of Asia.

Chinook salmon is the largest species of anadromous Pacific salmon. Chinook salmon enters the rivers of the Far East, Kamchatka, and Sakhalin. Also common along the entire Pacific coast of North America. There they call it King Salmon.

Char is also salmon-colored with many forms. Sedentary lake and lake-river species are medium-sized – up to 1.5 kg. The migratory char is large, up to a pound. Some types of loaches are listed in the Red Book.

Sima or cherry salmon. The most southern, heat-loving form. A distinctive feature from other salmon is a large number of large spots. At sea, the salmon has a silvery color, but when going to spawn it becomes darker, the spots clearly appear, and the color becomes completely variegated. A passing Sim grows up to 6 kg in weight. Sedentary forms are formed. Some male sims do not roll into the sea and live permanently in rivers. In appearance, these are small fish up to 20 cm long, always having a mating color. I caught exactly this kind of salmon, a pied salmon, on a spinning rod in streams when I was visiting Primorye.

Whitefish is a large subfamily of the salmon family. Includes species such as Vendace, Omul, and numerous varieties of Whitefish. Distribution area of ​​whitefishes: Europe, North America, Siberia, Ural. Many of the whitefish are listed in the Red Book.

Omul is a fish of the salmon family, subfamily of whitefish. The fish is migratory. Lives in coastal areas of the Arctic Ocean. It comes to spawn in the rivers of Siberia, Alaska, and Canada. The sedentary form, Baikal omul, is a famous dried snack for beer when vacationing on Lake Baikal, or passing by these places.

Grayling is not very similar in appearance to salmon, rather closer to whitefish, but separated into a separate subfamily. Grayling is easily recognized by its huge dorsal fin, like a sail. There are many subspecies of grayling: West Siberian, East Siberian, Baikal, Amur, Kamchatka, European, Alaskan. Grayling fishing is very interesting.

Catching a large specimen is the longed-for dream of many spinning and fly fishermen.

Far Eastern trout

What is salmon fish, and what species are called so?

The salmon family appeared on the planet quite a long time ago. Ichthyologists believe that the ancestors of this fish species existed approximately several tens of millions of years ago. Of course, their appearance was seriously different from their modern relatives. It is the advanced age of the family that explains the wide species composition. Currently, scientists classify about 50 different species as salmon.

It is important to immediately note that the name salmon is a collective name for the fish. And if Atlantic salmon is synonymous with salmon, then with its Far Eastern and Siberian relatives everything is much more complicated. If we adhere to scientific terminology, then the salmon family includes 3 subfamilies:

Far Eastern and Pacific salmon

If we consider the Far Eastern and Pacific representatives of the fish fauna, we can say that the salmon family includes: pink salmon, chum salmon, sockeye salmon, chinook salmon, and coho salmon. The latter is the lowest fat fish - 6%. Because of its appearance, coho salmon are often called silver salmon (in the old days - white fish). It can reach a weight of 14 kg, its length is more than 80 cm. But mostly medium-sized individuals, weighing 7-8 kg, go on sale. Coho salmon spawn later than all salmon - from September to March, sometimes under the ice. During spawning, female and male coho salmon turn a dark crimson color. It lives relatively little in the sea and becomes sexually mature already at 2-3 years. This is the most heat-loving representative of the Pacific salmon. Recently, the number of coho salmon has decreased sharply.

Pink salmon is the fish that ranks first in terms of catch for commercial purposes in the Far East. Its meat has a fat content of about 7.5%. But pink salmon is also the smallest fish of this family, its weight rarely exceeds 2 kg. The length of the individual is about 70 cm. Its body is covered with small scales. In the sea it is painted silver, the tail is covered with small dark spots. In rivers, the color of pink salmon changes: dark spots cover the head and sides. During the spawning period, males grow a hump, their jaws lengthen and curve. Beautiful fish during this period become simply ugly.

Chinook salmon in appearance resembles large salmon. It is the most valuable and largest fish among the Far Eastern salmon species. The average size of Chinook salmon reaches 90 cm. The back, caudal and dorsal fin are covered with small black spots. In the seas, this type of fish can live from 4 to 7 years. This is a cold-loving representative of the salmon family. All Pacific salmon spawn once in their lives and then die soon after.

Popular salmon fish and their description

It will be interesting and instructive for domestic fishermen to learn about those representatives of the salmon family that can be caught by an amateur fishing rod. Among them there are both trophy fish and small inhabitants of fast rivers.

Representatives of Siberian rivers

The three most popular representatives of the salmon family are found in Siberia. This is a large taimen, as well as its small relatives lenok and grayling.

Taimen is found in rivers and large lakes of Siberia, Altai and the Far East. This Siberian salmon can reach a length of over 1 m, and the weight of the giant reaches 60 kg. This fish is rightfully classified as a long-livers, since the age of individual individuals is 50 years.

It should be noted that the most catchy areas for fishing enthusiasts are the basins of the Amur, Lena, Yenisei and Lake Baikal rivers. In those regions where people mined gold, this fish, unfortunately, disappeared. A lot of taimen are still found in the hard-to-reach rivers of Yakutia and Evenkia. The main object of hunting for this predator is pike.

Currently, several varieties of taimen can be mentioned.

• The largest and most interesting for fishermen is the Siberian taimen. This is a typical freshwater fish with a large population and can grow up to 60 kg.
• Korean taimen has been poorly studied, and information about it is controversial.
• Until recently, Danube salmon was on the verge of extinction. However, recent research gives ichthyologists optimism.
• Sakhalin taimen, despite the common name, is not related to taimen. This is a migratory fish species, while all taimen are freshwater inhabitants.

Lenok is widespread in Siberian rivers. In this species of fish, a distinction is made between blunt-snouted and sharp-snouted modifications. Lenka is abundant in the Far Eastern, Mongolian, Chinese and West Korean rivers.

Lenok lives in the upper reaches of cold and fast rivers. Small individuals up to 40 cm long and weighing up to 1 kg live in flocks. And large individuals up to 90 cm long and weighing up to 6.5 kg prefer to live alone.

There is some disagreement among ichthyologists regarding the species diversity of lenoks. There are basically two camps. One of them contains blunt-snouted representatives, and its competition comes from sharp-snouted relatives. While the former tend to feed on insect larvae, the latter specialize in rodents. The largest weight of lenok caught was 8 kg.

This representative of salmon is distributed in all reservoirs of Siberia. Large populations are found in the tributaries of the Amur, Ob, Yenisei, Lena and Lake Baikal. All graylings differ in their coloring. Scientists distinguish 4 varieties:

• West Siberian;
• East Siberian;
• Kamchatka;
• American (Alaskan).

Grayling is one of the smallest representatives of salmon. Having reached the age of 10 years, the fish is able to gain weight of about 2 kg and grow up to 50 cm.

Atlantic salmon

In addition to salmon, the group of Atlantic or noble salmon includes brown trout and trout.

• Salmon is considered one of the most delicious fish. This representative of salmon can reach 1.5 m in length and 45 kg in weight. The habitat of salmon is not limited to the Atlantic Ocean; the fish also thrives in the cold waters of the Arctic Ocean.
• Brown trout are also lovers of cold water, but this fish is more attached to freshwater areas. Even when at sea, she tries to stick to the coastal zone.
• Trout even resembles brown trout in appearance, which confirms their close relationship.
• In the south of the Atlantic, a Caspian population can be distinguished, some representatives of which gain weight of 50 kg.

The noble salmon that live in northern waters are very popular among fishing enthusiasts. Even in the Neva there are specimens weighing 40 kg.

Pacific salmon

Pacific or Far Eastern salmon comprise 6 species of fish that breed in freshwater bodies. In them, adult individuals die after spawning. Residents of the Far East especially value chum salmon and pink salmon.

• Pink salmon is the most abundant Far Eastern salmon. The distinctive features of this fish are the presence of round black spots on the caudal fin. If we compare pink salmon with other Pacific relatives, they have a thicker caudal peduncle. The fish cannot boast of its size; the length rarely reaches 75-80 cm, while the weight is limited to 5.5-6 kg. Before spawning, pink salmon changes color, it develops a hump, and the shape of its jaws changes.
• The second largest species of Far Eastern salmon is chum salmon. The size of an adult individual can reach 1 m with a weight of about 15 kg. Unlike other relatives, when entering fresh waters before spawning, the fish does not change in appearance.
• Pacific salmon also includes such well-known fish species as coho salmon, nelma and chinook salmon.

Brief description of salmon fish. Salmon

Let's take a closer look at what some fish of the salmon family are. The list opens with northern salmon (noble salmon) or salmon. This large and beautiful species of fish lives in the White Sea basin. The meat of this representative of salmon is very tasty and tender, reddish in color. It is rich in various beneficial substances and vitamins. Salmon is distinguished by its large size, its length is up to 1.5 meters and its weight is 40 kg. In terms of cost, salmon meat is more expensive than all other representatives of the salmon family.

The body of the salmon is covered with small silvery scales; spots on the lower lateral line are completely absent. This fish of the salmon family feeds in the sea on crustaceans and small fish. When she goes to spawn, she stops feeding and therefore loses a lot of weight. By the mating season, the appearance of salmon changes greatly: the body of the fish darkens, orange-red spots appear on the sides and head. In males, the jaws also change; a hook-shaped protrusion is formed in their upper part, which fits into the recess of the lower jaw.

Salmon spawns in the fall, and in some areas in the winter. The water temperature in the spawning grounds does not exceed 6 degrees Celsius, so the development of eggs occurs very slowly. Only in May do the young begin to hatch from the eggs and then live in fresh water for a long time. Juveniles do not at all resemble their adult relatives - they are active and colorfully colored fish. After 5 years, they approach the mouths of rivers and, having reached a size of 9-18 cm, go out to sea. At this time, their body is covered with silvery scales.

Recreational salmon fishing

All salmon, from the huge taimen to the char or pied, are typical predators. Some hunt for large fish or rodents, others grab small fish and insects that have fallen into the water. Accordingly, amateur salmon fishing is based on the predatory tendencies of this family. Most often, fishing is carried out in several ways.

1. Fly fishing is considered aesthetic fishing. It is suitable for both catching small trout and hunting large salmon. In each case, it is necessary to assemble a suitable fly fishing rod and select the appropriate artificial baits. In fly fishing, a lot depends on the angler’s ability to cast a light fly accurately and far. Most salmon are quite cautious, especially since they live in clear water.

1. Fans of spinning fishing can also count on a good salmon catch. The strength of the gear is determined by the amount of possible production. For trout fishing in ponds or small rivers, an ultralight spinning rod equipped with a small “meat grinder” and thin fishing line is suitable. Turntables, spoons and wobblers are used as bait. If you are going to catch large representatives of salmon, then the main criterion for spinning tackle will be strength. Lures can be of different types, but their size must be large.
2. On large lakes, trolling can be successful. For successful fishing, long (15 cm) but narrow spoons are selected. Minnow-type wobblers about 10 cm long also work well. A fisherman’s arsenal should have baits that can play consistently in different layers of water.

There are many places in Russia where you can hunt for salmon. It is important to follow the rules of amateur fishing that exist in each region. After all, the populations of many species of noble fish are declining from year to year. The task of real fishermen is to preserve all the diversity of ichthyofauna for our descendants.

Atlantic salmon

The lifestyle of this family is practically no different from that of Pacific or Far Eastern salmon. This species includes the Baltic, Caspian and Black Sea varieties, as well as salmon, trout found in streams and lakes, and brown trout. The latter, in particular, prefers to live in the northern seas, although it has a great affinity for fresh water. Even when this species of Atlantic salmon is in marine waters, it continues to stay close to the shore. As for trout, experts believe that it originated from brown trout. This is due to their external similarity.
