redtreecoralwithyeyerockfish.jpgThe Alaska Marine Conservation Council works to ensure that fisheries and other uses of the ocean are managed for  long-term health of marine ecosystems. AMCC promotes clean fishing practices and supports measures that protect habitat, minimize waste and prevent overfishing. 

Protecting the health of our marine ecosystems demands that we also address the significant threat of climate change and ocean acidification to the marine environment and our coastal communities.

 

Limit bottom trawling to protect habitat and minimize bycatch

The impacts of bottom trawling include damage to seafloor habitat and high amounts of bycatch. Bottom trawling damages living seafloor habitats by overturning boulders, crushing corals and other habitat-forming structures and altering biological communities.

The large nets catch not only the target fish species, but everything else in the net's path including large amounts of unwanted fish and other marine life. Once hauled aboard the vessel, the unwanted species are discarded dead or dying as bycatch.  In Alaska’s waters, hundreds of millions of pounds of unwanted marine life is thrown back into the sea each year. AMCC supports solutions to minimize bycatch.

AMCC collaborates with the Bering Sea Elders Group on a vision for the northern Bering Sea. 

In the Gulf of Alaska, fishery management plans now under developed include an expansion of bottom trawl groundfish fisheries. An increase in bottom trawling effort will increase pressure on the recovering Kodiak Tanner crab population either through bycatch, unobserved mortality due to rolling trawl gear over crab or by impacting sensitive habitats.

AMCC is working with fishermen to protect Kodiak Island Tanner crab. Kodiak fishermen are mapping habitat areas important to Tanner crab around Kodiak Island to identify places that may need protection from bottom trawl gear.
