This book was released on 1977 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: An apparently contiguous stock of American lobsters, Homarus americanus, is concentrated along the outer continental shelf margin and slope from Corsair Canyon westward and southward to the region of Baltimore Canyon. Between April 1968 and May 1971 we captured, tagged, and released a total of 7, 326 lobsters at 52 localities between Corsair Canyon and Baltimore Canyon. As of December 1972, 945 recaptures (12.9% recovery) had been reported, providing a basis for interpretation of seasonal and long-term movements, as well as measurements of growth rate and moult frequency. A classification scheme is developed and applied to distinguish between apparently directed seasonal movements (migrations), localized movements of less than 10 nautical miles (18.5 km), and long-period (>120 days) dispersions of 10 miles or more. This last category includes point to point tracks that cannot be objectively resolved in terms of directionality and may represent random dispersal, a summation of seasonally directed tracks, or both. We conclude from the track analyses that at least 20% of the offshore lobsters annually engage in directed shoalward migrations in spring and summer with return to the shelf margin and slope in fall and winter. This conclusion is reinforced by independent analysis of the time/depth/temperature associations of tagged lobsters at recapture which, of itself, suggests that an even larger proportion of the offshore lobsters annually effect directed migrations in response to seasonal temperature variations.

Available in PDF, EPUB and Kindle. Book excerpt: Crustaceans adapt to a wide variety of habitats and ways of life. They have a complex physiological structure particularly with regard to the processes of growth (molting), metabolic regulation, and reproduction. Crustaceans are ideal as model organisms for the study of endocrine disruption and stress physiology in aquatic invertebrates. This book

This book was released on 1998 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proceedings of a symposium that focused on new, innovative evaluation of the implications and needs for changing management approaches and demands in invertebrate fishery science. Species covered in the presentations include crustaceans, gastropods, echinoderms, and bivalves. Presentations are organized in the following subject areas: assessment of abundance and related parameters; growth, mortality, and yield per recruit; spatial pattern and its implications; the fishing process; population dynamics; the fishery as a selective force; invertebrate fisheries management; and regional perspectives from the north Pacific. The proceedings conclude with a symposium overview.
