| Economic losses: | Hard to quantify but major. Commercial dungeness crab industry had a delayed start then a closure for domoic acid in crab sampled during an open fishery. Major econmic loss and disruption to the industry and market. Loss of market confidence. | |||||||||||
| Management decision: | Razor clamming closed along entire coast for much of the year. Delay and then closure of part of dungeness crab fishery. | |||||||||||
