Answer 2

Answer:

Atlantic salmons are born in rivers, and as they grow, they move and migrate to the ocean. Salmons usually migrate during fall. In They spend most of their life in the ocean to gain body mass, and as they mature, they tend to go back to the river after about 2-3 years to spawn. The ultimate goal of the salmons upon returning to the river is to ensure reproduction and survival of their offsprings. This kind of migration became adaptive to other salmons because of their instinct that the salmon's birthplace is a good site of spawning and survival of offspring
