Sep 2, 2021 · Deep beneath Alaska’s cold waters dwell some of the world’s most diverse and abundant sponge communities. These living structures provide essential habitat and refuge for many commercially important fish. Identifying sponge species and where they live is key information for ecosystem-based fisheries management in Alaska.

Commercial species supported by rich sponge habitat include fish such as rockfish, Pacific Ocean perch, flatfish, Atka mackerel, golden king crab, shrimp, Pacific cod, Pollock, greenling, Greenland turbot, and sablefish. Non-commercial species include sea stars, nudibranchs, octopuses, snails, crinoids, basket stars, sponges, and anemones.
