"Salmon" is a commercial name, can refer to the salmon family below the 10 genera, hundreds of species, can also refer to the salmon genus below dozens of species; to China's current laws and regulations, that is, some merchants label grass carp on the "salmon" to sell, if you sue him for fraud will definitely be your defeat; in real life, in most cases, if there is no special instructions, salmon refers to the Atlantic salmon Salmo salar.
Salmonidae has a total of 10 genera, of which 5 may be related to "salmon", namely: Hucho, Pacific salmon genus Oncorhynchus, salmon genus, salmo, salvethymus, salvethymus.
Of these 5 genera, dozens of species, the most common are the Pacific salmon genus Oncorhynchus and salmon below 7:
1. Oncorhynchus tshawytscha: Also known as king salmon. English king salmon, chinook salmon
2. Salmon (Oncorhynchus keta): also known as salmon. English. Chum salmon, dog salmon
3. Red salmon (Oncorhynchus nerka nerka): Also known as red salmon. Red salmon, blueback, quinalt
4. Hunchback salmon (Oncorhynchus gorbuscha): Also known as whitefish. Pink salmon, humpback salmon
5, silver salmon (Oncorhynchus kisutch): also known as silver salmon. Coho salmon, silver salmon
6. Oncorhynchus mykiss: Also known as rainbow trout. English Rainbow trout
7, Atlantic salmon Salmo salar: also known as salmon. Atlantic salmon, salmon
Oncorhynchus tshawytscha: also known as king salmon
Oncorhynchustshawytscha, sometimes referred to as chinooksalmon, salmon, salmon, spring salmon, black-billed salmon, is a species of salmon, salmon family, north Pacific edible fish with pale spots, scientific name Oncorhynchustshamptscha, can grow up to 40 kg, usually 5-10 kg. It is one of the least resourced salmon species in the United States, but it is also the largest and most expensive of the five Pacific salmon species.
Salmon are widely distributed in the North Pacific, from the Yukon River in Alaska in the east, to the Sacramento River in Central California in the south, and to the Kamchatka Peninsula in Russia and northern Japan in the west. It can be fished in the United States from the Yukang River on the Bering Sea in Alaska to Central California.
We often eat sashimi, generally are Norwegian farmed king salmon, this price is the most expensive, the meat is the fattest, the meat is very high in fat, after the fish meat is cut, you can clearly see the orange meat sandwiched with white fat, the texture is very beautiful.
Oncorhynchus keta: also known as dog salmon
Chum Salmon, also known as salmon, commonly known as autumn salmon, is one of the salmonids of the family Salmonidae. It is found in the North Pacific Ocean, from Japan, South Korea, the east coast of Siberia to the Bering Sea, China's Heilongjiang, Tumen River, Suifen River and other water systems, British Columbia in Canada and Alaska and Oregon in the United States.
Salmon live at a depth of 0 to 270 m, with a flattened body and a relatively symmetrical dorsal ventral outer contour, spindle-type. The head length is slightly equal to the height of the body, the mouth is at the end, the mouth is large, and the maxilla extends back to the posterior edge of the eye, obliquely downward, resembling a bird's beak. The upper and lower jaws and the plough bones have teeth, and the jaw teeth are large and sharp. The eye is below the body axis, larger. The dorsal fin is located later in the center of the body, the ventral fin starts behind the dorsal fin, and the caudal fin is shallowly forked. There are fat fins. When swimming back down the river, the dorsal side of the body is yellow-green, the abdomen is silvery-white, and over time, the body color gradually darkens, and 10 to 12 purple-red longitudinal stripes appear on the body side. When you reach the spawning ground, the entire body color becomes dull. Body length up to 100 cm.
The quality of salmon varies greatly, so be very careful when purchasing. As with other wild salmon, when salmon go upstream to spawn, the silvery appearance begins to darken and the red flesh begins to fade. Salmon with a bright silver appearance and ochre red flesh are of the highest quality. Salmon with a dark cyan appearance and light and gray flesh are of lower value.
3. Sockeye Salmon
Red salmon is the most valuable salmon species in the United States, with the second largest production. Red salmon get their name from their deep red flesh. Although red salmon are widely distributed in the waters of the North Pacific from northern Japan and Russia to Washington state, American red salmon production accounts for more than 80% of the world's total red salmon production. Red salmon can be caught almost all summer. Alaskan salmon fishing season begins in mid-May near the Copper River near Prince William Bay. Although production here is relatively small, about 2,000 to 3,000 tonnes, the price is higher than other red salmon, because the red salmon produced here is larger and has a large oil content.
Identification features: Red salmon has no black spots, can be distinguished from king salmon and pink salmon, red salmon scales are small, fish tail is thin, according to this can be distinguished from dog salmon.
Pink Salmon
Whitefish, also known as hunchback salmon and fine-scaled salmon, are fish of the salmon family Cannabis salmon genus. It is widely distributed in the northern and coastal rivers of the Pacific Ocean, as well as the Suifen River and the Tumen River, and is a migratory fish. Pink salmon is pale red (from which pink salmon gets its name) and has a moderate taste, similar to trout.
In the ocean, hunchback salmon are bright silver in color. When it migrates to the stream where it spawns, it turns pale grey in color and pale white in its belly. This fish is characterized by a white mouth with black gums, no teeth, and large oval black spots on the back and V-shaped tail. The average weight of humpback salmon is 2.2 kg. The maximum recorded length is 76 cm and the weight is 6.8 kg.
5. Silver salmon
Silver salmon is a genus of teleost fish radiata fin subclass, salmonids, salmon suborder, salmonidae, salmonids. Place names: salmon, salmon, salmon, salmon, salmon. Commonly known as: Northern trout, Dafa salmon, Dafa salmon, Guoduo fish, Luo Pot fish, Lone East fish, Qimu fish, QiMeng fish, spotted trout, flower trout.
Silver salmon: A small silvery white edible and fishing fish (silver salmon), grown in the North Pacific water system, later introduced to the Great Lakes of North America also known as silver salmon, Russian Кижуч. The tail of the silver salmon has no dark spots and has gray gums, which can be distinguished from the king salmon (the king salmon has small black spots hanging on both sides of the tail, and the gums are black). Silver salmon tails are thicker, while dog salmon tails are thinner.
6. Rainbow trout
Rainbow trout ( Scientific name : Oncorhynchus mykiss ) is a genus of salmonids , salmonids , and fish. Maximum body length: 120cm, habitat depth: 0-5 meters, known as "water ginseng". It inhabits lakes and rapids and has a brightly colored body. There are small black spots on the body cloth, and there is a red band on the side of the body, like a rainbow, so it is named "rainbow trout".
Rainbow trout are long and slightly flattened. The kiss is round and blunt. The mouth is large and slightly oblique upwards. The jaw teeth are well developed. Big in the eye. The body is scaled by the state. Gastric curved tubular. The dorsal fin starts in front of the ventral fin and has a fat fin behind it. The pectoral fin is small and does not reach the ventral fin. The caudal fin is forked. The back of the body is pale green or yellowish green, the ventral fins are off-white, and the sides are silvery white. The head, dorsal, bodysides, and fins are scattered with varying numbers of small black spots. Sexually mature individuals have a wide iridescent band along the lateral line, which is particularly gorgeous during the reproductive period. Mature males have enlarged jaws. Bend upwards into a hook shape.
7. Atlantic salmon
Atlantic salmon (Salmo salar), commonly known as "salmon". The original habitat was the northern Atlantic Ocean, northeast of North America, along the Scandinavian coast of Europe, and was a genetic variability ratio
Relatively stable, high nutritional value of worldwide farmed fish.
Atlantic salmon are fusiform in shape and have well-developed teeth. All fins have black edges except for the adipose fins. Atlantic salmon juveniles differ from adults. While they are still living in freshwater, they have blue and red spots on their bodies. When they enter the sea, they turn silvery blue. They are most easily recognizable by the black spots on their lateral lines. When they reproduce, the males are pale green or red.
Norway, Chile, Canada, the United Kingdom, the Faroe Islands, Russia and Tasmania are the main breeding grounds for Atlantic salmon.
VIII. Supplements:
1, almost all the fish of the Pacific salmon genus can be called "salmon",
2. Most migrating Pacific salmon die after spawning.
3, Mackey hook trout is the famous "rainbow trout". Rainbow trout; this is what is cultivated in lakes in the country.
4, almost all salmon are cold water fish, except for "rainbow trout".
5. "Rainbow trout" has a reddish meat quality and a rough mouth. The price is less than half that of Atlantic salmon
6, Atlantic salmon and "rainbow trout" are artificially raised, king salmon, dog salmon, whitefish, red salmon, silver salmon are wild
7, wild salmon is not recommended to eat raw, because there are parasites. Artificial breeding can reasonably control the risk
8, wild salmon is not suitable for raw eating, because the amount of exercise is large, the muscles are very tight.
9) Norway's three fishes are very famous, but since the Nobel Peace Prize was awarded to Chinese political prisoners in the previous two years, the Chinese government has cut the import quota by 99%. What everyone eats today is, legally speaking, Norwegian salmon
10, China imports a large number of salmon from the Faroe Islands in Denmark to replace Norwegian salmon, in essence, There is no difference between Norwegian and Danish fish.
11, Atlantic salmon has high requirements for the quality of water bodies, and it cannot be fed with a little pollution
12. It is not excluded that there are also parasites in the body of northern European salmon, but it is not a significant hazard
13. The topic of parasites in salmon has not yet been conclusive and authoritative.
