Crab Pots
Lost crab pots are destroying (killing) up to 25% of the yearly crab population. CSAS actively supports surveying and pinpointing of these pots for removal by divers. In the above image approximately 30 commercial crab pots are entangled and lost. The below image shows work done for the Jefferson County Marine Resources Council to understand the prevalence of lost crab pots in Discovery Bay. More than 100 were found in the entry to the bay alone.

More than 100 derelict crab pots were identified in a trial pass at the mouth of Discovery Bay Washington. This project has now been funded for clean-up.
Fishing Nets
Lost fishing nets pose an ongoing hazard to all sea life and continue to fish (kill) indefinitely. Nets can be found on most wrecks, rock outcroppings, and, in the below images, an underwater forest.
