Movement, Growth, and Mortality of American Lobsters, 'Homarus americanus', Tagged Along the Coast of Maine

摘要

During the spring of 1975, 2,982 American lobsters, Homarus americanus, were tagged at three locations off Maine. Four months after release 65% of the lobsters had been returned and by the completion of the study in September 1977, 2,188 (75.9%) lobsters had been recaptured. The majority of lobsters traveled shoreward or along the coast on a west to southwesterly course with minimal easterly movement. Extremely high annual instantaneous fishing mortality rates (4.0-7.3) estimated for each release area confirm the overexploitation of the Maine inshore lobster fishery.
