Salmonid Fish – Beauty of Pacific Ocean

The Kamchatka Peninsula is a 1,250-kilometer long peninsula in the Russian Far East. It lies between the Pacific Ocean to the east and the Sea of Okhotsk to the west.

Kamchatka contains probably the world's greatest diversity of salmonid fish, including all six species of anadromous Pacific salmon (chinook, chum, coho, seema, pink, and sockeye). Biologists estimate that a sixth to a quarter of all Pacific salmon originates in Kamchatka.

Kuril Lake is recognized as the biggest spawning-ground for sockeye in Eurasia. In response to pressure from poaching and to worldwide decreases in salmon stocks, some 24,000 square kilometers (9,300 sq mi) along nine of the more productive salmon rivers are in the process of being set aside as a nature preserve.

Salmon is the common name for several species of the family Salmonidae. Several other fish in the family are called trout; the difference is often said to be that salmon migrate and trout are resident, a distinction that holds true for the Salmo genus. Salmon live along the coasts of both the North Atlantic (one migratory species Salmo salar) and Pacific Oceans (approximately a dozen species of the genus Oncorhynchus), as well as having been introduced into the Great Lakes of North America.

Typically, salmon are anadromous: they are born in fresh water, migrate to the ocean, then return to fresh water to reproduce. However, there are populations of several species that are restricted to fresh water through their life. Folklore has it that the fish return to the exact spot where they were born to spawn; tracking studies have shown this to be true but the nature of how this memory works has long been debated. Salmon are intensively produced in aquaculture in many parts of the world.
