Lobster Assessment

The lobster program provides information necessary to maintain a fishery in Long Island Sound with large, stable landings, which does not remove so many mature lobsters that the resource is jeopardized. Combining catch of all ages of lobsters from the Marine Resource Survey, plankton net, and commercial harvest, Fisheries staff have calculated mortality rates approximating 90% annually for the last decade. This information has shown that very few lobsters live long enough to molt more than once after reaching legal size. The result is that the abundance of each year's stock of lobsters available for harvest depends almost entirely on the recruitment of sub-legal lobsters molting to legal size that year. Staff are continuing a juvenile and adult sampling program which will provide data for a mathematical model that will accurately describe and predict mortality, growth and recruitment rates for the Sound's lobster population under various management scenarios. This tool will provide the ability to examine the effects of changing the legal length limit, of reducing fishing effort, or of other management options. The Sound's lobster population supports Connecticut's second most valuable commercial fishery (surpassed in dollar value only by oyster landings), as well as a popular recreational fishing opportunity.
