Nine Species of Deep-Sea Sponges Discovered in Alaska

September 11, 2026 — Scientists have discovered nine new species of sponges in the Gulf of Alaska and Aleutian Islands. The specimens were collected during the Alaska Fisheries Science Center’s long-standing annual bottom trawl surveys, which monitor the condition of groundfish and shellfish stocks in Alaskan waters. For these sponge studies, researchers analyzed samples gathered during surveys dating back to 2012.

The new species were described across two recent scientific publications: four in one paper and five in the other. These discoveries raise the total number of known sponge species in Alaska to 232. The findings add to a growing body of knowledge about the richness of marine life in Alaskan waters. They also highlight the Aleutian Islands as a global hotspot for sponge biodiversity.

The studies also mapped sponge genetic codes, which contributes to a marine genetic library. This continues to build a robust catalog that enhances NOAA’s ability to detect species and estimate population abundances using non-invasive environmental DNA sampling.

Sullivan reintroduces sweeping bill targeting bycatch, seafloor impacts

July 8, 2026 — U.S. Senator Dan Sullivan (R-Alaska) has reintroduced the Bycatch Reduction Act, legislation that would expand federal efforts to reduce bycatch, limit seafloor impacts from trawl gear, improve fisheries monitoring and increase transparency in fishery management.

According to Sullivan’s office, the bill builds on recommendations from the Alaska Salmon Task Force, which was created through legislation he authored and signed into law in 2022.

The proposal would establish new standards and monitoring requirements designed to keep both midwater and bottom trawl nets off the seafloor, require proven salmon excluder devices on pollock vessels, invest in salmon tagging and genetic sampling, expand ecosystem research, and create a new flume tank testing facility to evaluate fishing gear under simulated ocean conditions. The bill also would reauthorize NOAA’s Bycatch Reduction Engineering Program and encourage fishermen to test new gear and technologies aimed at reducing bycatch and habitat impacts.

NOAA Launches New Season of Discovery in Alaska’s Deep-Sea Coral and Sponge Ecosystems

June 10, 2022 — In the cold dark depths of the North Pacific Ocean, corals and sponges create living habitat for an abundance of life—including some of Alaska’s valuable commercial fish and shellfish.

This summer, Alaska Fisheries Science Center researchers and partners will embark on three expeditions to explore deep-sea coral and sponge habitats in the Gulf of Alaska. Advanced sampling technologies like stereo cameras, ROVs and environmental DNA (eDNA) will make it possible to survey vast areas in a noninvasive and cost-effective manner. The team will discover where corals and sponges are diverse and abundant. They will also learn about coral and sponge early life stages and growth. This knowledge will fill critical information needs for ecosystem-based management of Alaska’s fisheries in a rapidly changing ocean.

“The overarching goal is to conserve and protect unique habitats,” said project lead Christina Conrath, NOAA Fisheries Alaska Fisheries Science Center. “The first step is learning where important habitats are and how important they are to supporting fish and the ecosystem. That’s what we’re doing now.”

Deep-sea Coral and Sponge Ecosystems

Corals and sponges form complex habitat for a multitude of animals. This structure offers protection, feeding opportunities, and nursery areas for commercial species like rockfish, spot prawns, and golden king crab. Some fish deposit their eggs in sponges where they are not only protected from predators, but may also benefit from the sponge’s natural antifungal and antibacterial activity.
