Description
Summary:We propose to conduct a retrospective analysis of Kodiak red king crabs (Paralithodes camtschaticus), pursuant to the North Pacific Research Board’s (NPRB’s) request for proposals, Component 1, Project Need 3(c). We will analyze historical data from pot and trawl surveys and commercial fishery landings to reconstruct historical Kodiak king crab abundance, potential stock-recruit relationships, and investigate causes of major shifts in stock abundance and geographic distribution over the last 45 years. The decline of this stock and its continued failure to recover after 22 years of fishery closures remains a most perplexing fishery mystery. Kodiak once supported the largest red king crab fishery with peak landings of 94.4 million pounds (43,000 mt) worth $12.2 million ($0.13/lb) in 1965. If recent prices ($4.70/pound) paid for Bristol Bay king crabs are indicative of potential current value, these landings might have been worth $443.8 million in 2004. Not surprisingly, there is considerable interest among many stakeholders for potential crab stock enhancement. Alaska’s coastal communities have suffered in recent years from depressed salmon prices, declines in herring prices and landings, continued shrimp fishery closures, and increasing groundfish fishing restrictions in attempts to stem marine mammal declines. A retrospective analysis of the Kodiak king crab stock is a prerequisite to understanding the conditions surrounding its rise and collapse, failure to rebuild, and the prospects for rebuilding. Our study will analyze the roles of
