This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overarching goal of this thesis was to enhance our understanding of the implications of benthic movements by American lobster Homarus americanus to the species' ecology and demography. The first chapter discusses the use of an ultrasonic telemetry system to track juvenile lobsters in nature for the first time. Juveniles were highly active and mobile, and they behaved as "central place foragers", which kept them on productive but patchy nursery grounds despite the extensive movements they displayed. Juveniles did not display an increase in time spent outside of shelter or average daily home range with increasing body size, as was predicted in the literature. The second chapter discusses the use of two complimentary ultrasonic systems to simultaneously track juvenile, adolescent and adult lobster for the first time. This study confirmed some of the observations made in Chapter 1, such as lobsters being very active, displaying diurnal activity rhythms (more active at night than during the day), and behaving as central place foragers, as well as juveniles not demonstrating an increase in activity with increasing body size. It did, however, reveal ontogenetic changes in behavior over the expanded size range, with daily home range increasing gradually with increasing body size, and study length displacements being markedly greater for adolescents/adults than for juveniles. The third chapter re-analyzed data from an extensive mark-recapture study conducted in the southern Gult of St. Lawrence between 1980-1996 to estimate, for the first time, the relative contribution of benthic movements and larval dispersal to demographic connectivity in lobster. Estimates of pelagic and benthic movements were comparable, when accounting for the fact that adults can disperse over the course of several years while larvae disperse over a single season only. This novel finding, along with the fact that benthic movements are not constrained by currents the way pelagic dispersal is, and that lobsters move relatively little in our study area compared to other parts of the species' range, suggest strongly that more consideration should be given to the contribution of benthic movements to connectivity and stock structure in the management of the American lobster.

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.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examined American lobster (Homarus americanus) habitat and movements within Minas Basin and Minas Passage in advance of turbine installations at the FORCE test facility in Minas Passage, Bay of Fundy. Prior environmental assessment data, modeled current speeds and biogeophysical data from seafloor grab samples and seafloor video footage taken during the CCGS Hudson scientific cruise 2013-13 were used to prepare lobster habitat suitability maps for the Minas Basin, Minas Passage and Minas Channel. Although habitat quality varied spatially, most of the surveyed region represented good lobster habitat; less suitable areas were found with localized harsh conditions, e.g. scoured seafloor or high bottom drag. Vemco acoustic telemetry tags and VR2w receivers were used to track seasonal movements of lobster. Strategically deployed acoustic receivers were used to test the hypothesis that lobster move outward from Minas Basin through the FORCE test area in Minas Passage during late fall and inward in spring. A total of 125 adult lobsters were sourced from commercial catches in 2011 and 2012, fitted with Vemco acoustic transmitters and numbered disc tags, and released in Minas Basin. A total of 40-tagged lobsters (34 from 2011, 6 from 2012) were detected in Minas Passage, including FORCE and/or Minas Basin. More females than males were detected in Minas Passage; within both sexes, movement rates were variable. Although seasonal outward movement was detected for some lobsters, it appears that a portion of the population overwinters in Minas Basin. This conclusion is supported by two years of lobster tracking and interviews with six LFA 35 lobster fishers.

Book Synopsis The Biology and Management of Lobsters by : J. Stanley Cobb
Download or read book The Biology and Management of Lobsters written by J. Stanley Cobb and published by Elsevier. This book was released on 2012-12-02 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume work presents a summary and review of the current state of lobster biology, ecology, physiology, behavior, and management. It emphasizes the biology of clawed lobsters (Nephropidae) and spiny lobsters (Palinuridae), with attention also given to slipper lobsters (Scyllaridae) and coral lobsters (Synaxidae).The first chapter of Volume 1 provides an overview of the general aspects of lobster biology that serves as an introduction for readers of both volumes. Subsequent chapters examine the topics of growth, neurobiology, reproduction, nutrition, pathology, social behavior, and migration patterns.The chapters in Volume II consider the ecology, population dynamics, fishery biology, and aquaculture of spiny and clawed lobsters. The topics selected in both volumes represent areas of current research whose findings have not been previously synthesized into a coherent form.An important feature of these volumes is the emphasis on the interaction between biology and management and culture. Many of the contributors have done research in both applied and basic biology and can articulate both points of view. The interaction between basic and applied research is of fundamental importance in these volumes in which management aspects of the research have been integrated with the basic biology of lobsters.The Biology and Management of Lobsterswill be of interest to crustacean biologists, marine biologists and ecologists, zoologists, physiologists, animal behavior researchers, aquaculturalists, fisheries biologists and managers of fisheries, neurobiologists, pathologists, and food scientists.
