"salmon" 的定义和意义

What is a "salmon"?

A salmon is an iconic migratory fish known for its incredible journey from freshwater to the open ocean and back again to spawn. They have streamlined bodies and are typically silvery in color, with a distinctive pattern of dark spots. Salmon are native to the northern Atlantic and Pacific oceans, as well as the rivers and streams connected to them. They are renowned for their remarkable ability to navigate long distances and overcome challenging obstacles, including strong river currents and natural barriers. Salmon are anadromous, meaning they are born in freshwater, migrate to the ocean to mature, and return to their natal rivers to reproduce. They are highly valued for their nutritious flesh and are an important food source for humans and wildlife alike. The life cycle of salmon is a testament to their resilience and their vital role in the ecosystems they inhabit.
