Fish and Invertebrates


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

Although most of the waters that provide prey for refuge wildlife are not within the refuge, by establishment mandate the refuge is involved in the conservation of the marine resources upon which the seabirds and marine mammals rely.

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.
