Food habits: Salmon are carnivorous fish and mainly feed on zooplankton, shrimps and small fish. While living in the ocean, they are important predators.
Economic value: Salmon is an important commercial fishery resource and is valued by many countries and regions. Its meat is plump and nutritious, making it a favorite ingredient for many people.
To sum up, salmon is a fish that lives in seawater and has important economic and ecological value. They migrate to freshwater areas to lay eggs during their life cycle, but primarily live in the ocean.
