![]() ![]() The portion of this fishery in federal waters off the Maine coast is managed under a relatively small catch limit that is separate from the catch limit used to manage the rest of the quahog fishery (described above).The ocean quahog fishery off Maine is managed separately because of differences in biological, fishery, and market characteristics.Fishermen must maintain and submit logbooks of each fishing trip to document catch.Fishermen harvesting ocean quahogs from Georges Bank have additional requirements under the PSP testing protocol.Closed areas due to environmental degradation or to toxins that cause paralytic shellfish poisoning (PSP).These individual quotas can be sold or leased.

Once ocean quahogs have reached a certain size, they have a very low predation rate.Many animals prey on juvenile ocean quahogs, including invertebrates such as rock crabs, sea stars, and other crustaceans, and fish such as longhorn sculpin, ocean pout, haddock, and cod.They bury themselves in the ocean floor and pump oxygen-filled water and food particles in through their siphons, which extend above the surface of the ocean floor. They grow very slowly and do not start to reproduce until around age 6, and do not reach a commercially harvestable size until about age 20.East Coast, where the fishery takes place, ocean quahogs can live for at least 200 years. Ocean quahogs are among the longest-lived marine organisms in the world.The spawning season is sometimes extended over a number of months as quahogs release eggs and sperm a little at a time. Ocean quahogs spawn once a year, either in the summer or fall.Larvae drift with the currents for at least 30 days until they develop into juveniles and settle to the bottom. ![]() Ocean quahogs spawn by releasing eggs and sperm into the water column where the eggs are fertilized.
