"atlantic salmon" 的定义和意义

What is an "atlantic salmon"?

An Atlantic salmon, scientifically known as Salmo salar, is a species of fish native to the rivers and oceans of the North Atlantic. They are anadromous, meaning they are born in freshwater rivers, migrate to the sea to grow and mature, and then return to their natal rivers to spawn. Atlantic salmon are known for their sleek, silver bodies and powerful swimming abilities. They have a distinct life cycle, with juveniles spending several years in freshwater before migrating to the ocean, where they feed and grow. When ready to reproduce, adult salmon undertake an arduous upstream journey, overcoming obstacles such as waterfalls and rapids to reach their spawning grounds. Atlantic salmon is highly prized for its flavorful, pink-orange flesh and is a popular species for recreational fishing and aquaculture. Conservation efforts are in place to protect and restore populations of this iconic fish.
