Kodiak red king crab |
SCIENTISTS say 16 egg-bearing female crabs will serve as broodstock in a research project they hope will help rebuild Alaska's Kodiak red king crab fishery. In addition, 16 male crabs were captured for pathology and genetic analysis.
For a time during the mid-to late 1970s, Kodiak Island waters teamed with red king crab. Kodiak itself became the centre of a crab fishing bonanza. At its peak in 1980, fishermen harvested more than 130 million pounds of crab worth about $115 million. Fortunes were made, but the boom soon went bust. By 1982, crab stocks had collapsed and the fishery all but disappeared. Decades of fishing restrictions since have failed to return crab populations to anything close to what they were in their heyday.
Brian Allee, director of the Alaska Sea Grant College Program, said the time is right to try something new. Allee is leading the Alaska Sea Grant effort to bring fishermen, state and federal fishery managers, and university scientists together in a collaborative effort to breed king crab in captivity. If it proves successful, Allee said, researchers would seek state permits to conduct a pilot release of juvenile crab to learn whether crab cultured in captivity can survive in the wild.

Should fisheries be closed during breeding time to allow stocks to reach more sustainable levels?
