What is salmon?
Sockeye (Oncorhynchus Nerka) is a cold water fish that has adapted to life in the locations of fresh and salt water. Adult salmon spends up to four years in the salt water of the ocean before returning to the Greeks and streams on fresh water to lay eggs or sort out. Sockey's salmon differs from other types of salmon in that the juvenile spends part of his life in the lake associated with the river used for friction.
Determination of cold water ocean for salmon salmon along the Pacific coast of North America from Washington to Alaska. They are also located in the Bering Sea from Alaska via Siberia and south to Japan. These salmon are abundant in the rivers of freshwater and streams of Washington, Alaska and British Columbia.
Mature salmon salmon living in the ocean has silver colors with a slight blue shade. Their silver color, which is also referred to as blueback salmon, allows them to avoid predators. After entering Fresh Water, to change salmon to a bright red color to fitKal friend.
Red salmon woman extends or put eggs in the gravel of fresh water. The eggs are laid in the nests known as Redd and are fertilized soon after male salmon. After fertilization, the woman sweeps the tail over the gravel to cover the eggs. Then the next dose is proceeded and laid. During friction, salmon salmon can lay more than 2,000 eggs.
salmon eggs take two to four months for hatching, during which young salmon survives on the egg yolk inside the egg. After hatching, young salmon enters into the phase of his life cycle known as Alevin. Alevins look like small fish with a yolk bag in the shape of a balloon still attached to their bodies. They remain in the nest for several weeks and survive on food in the yolk bag.
It is when it is in Alevinustage that salmon is taught by the smell of water, plants and rocks of the area. The fragrance is what gives an adult salmon the ability to return to the same habitatSweet water for friction. Together, the odors are unique that salmon will travel thousands of kilometers to return to the river or downstream.
After Alevin's stage, young salmon Sockey will absorb the yolk bag and develop on the screed. As frying, salmon is about a thumb long and is able to finally leave the nest in search of food. At the age of several months, the screed acquires vertical stripes and becomes known as a parr. After one or two years, Parr develops on Smolt.
Smolt is directed to the ocean and his body begins to change so that he can survive in salt water. The groups of Smolts will gather at the mouth of the river and wait until their kidneys and gills develop sufficiently to adapt to the ocean. Adult salmon lives in the ocean about four years before traveling back to the river or stream for friction.
