Bears Fishing For Salmon

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.
