What is Chinook salmon?

Chinook salmon, also known as the scientific name oncorhynchus tshawtscha , is a large fish that is originally from the water off the west coast of North America. This species was found from Alaska to California and weighed £ 126 (57.27 kilograms).

This kind of salmon is blue-green on its back. The color of the fish becomes lighter towards the sides, where it disappears into a silver shadow. The stomach of Chinook salmon is white. Mature males who are ready for friction have a dependent upper jaw, while in women the nose is blunt in the shape.

both commercial and recreational fishermen try to catch this kind of salmon. Trolling, where the retracted hooks pull behind the fishing boat, is an effective way to catch them. Chinook salmon is also one of the most popular types of prey killer.

Salmon hatches in fresh water and spends the first year of life there. On topoint, young fish (Smelt) migrate into the salt water of the ocean. They spend one and five years there and return to fresh water, abY they emerged before death. During this phase of Chinook salmon life, coloring on the abdomen and fins of fish changes and can move from dark red tone to copper or deep gray color, depending on the age of the individual.

Before laying an egg with a female chinook salmon pulls out in the gravel of the river. He chooses areas where water is deep and fast for this purpose. Once the nests are ready, they put up to 14,000 eggs, which are then fertilized by a male.

The newly hatched Chinook salmon, known as Alevins , will not immediately turn off from the relative protection of gravel. Young fish are attached to the yolk bag when hatching and remain in the gravel until this nutrient source has been absorbed. The youth, called fry , emerge from the gravel nest at the end of winter or early in the spring.

recently hatched chinook salmon will eat first plankton and then move to insects asenlarges. Once salmon moved to the open ocean, its food sources have spread to crustaceans, octopus and sized. Mature salmon can travel thousands of kilometers to its home stream when it is time for friction period. During this time, the fish do not eat, which means that their condition deteriorates when moving towards the location where their eggs are laid.
