The abundance of seabirds and marine mammals that breed and raise their young on refuge lands is due to the banquet of marine foods in surrounding waters. 

Ocean Migrants

Some of the marine fishes are anadromous. They must return to freshwater to spawn the next generation after growing up faster and fatter in the ocean than they could have in streams or lakes. Salmon are a good example.

Freshwater Residents

On larger islands and on refuge lands along the coast, some of the streams and lakes also have freshwater fish populations that don’t migrate to the ocean.
