Book excerpt: Ovigerous American lobsters, Homarus americanus, undertake seasonal migrations thought to maximize temperature experienced by their embryos. Using satellite tags, we tracked two ovigerous females from Grand Manan between September 2013 and July 2014. The tags surfaced near Beaver Harbour, NB and Port George, NS, 33 and 123 km from the tagging location, respectively. Recorded depth and temperature for both lobsters were remarkably similar, reflecting shallow-to-deep and deep-to-shallow migrations in the fall and spring, respectively. A change in water temperature appeared to trigger fall movements, but probably not spring movements. An individual-based model indicated that our lobsters experienced higher temperatures than virtual lobsters moving randomly or not at all, but lower than the maximum possible. This study provides novel insights into the nature and function of these seasonal migrations, which represents an essential first step in our ability to predict lobster movements and hatch location in a rapidly changing ocean.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Systems Analysis and Simulation in Wildlife and Fisheries Sciences William E. Grant This hands-on approach provides guidance to the step-by-step applications of systems analysis and simulation to questions about ecological systems. At the same time, it explains general principles without requiring that readers have a strong background in mathematics, statistics, or computer science. Chapter 1 traces the development of systems ecology introducing basic concepts, while Chapters 2 through 5 present the four phases of systems analysis: conceptual model formulation, quantitative specification of the model, model validation, and model use. 1986 (0 471-89236-X) 338 pp. Bioeconomic Modelling and Fisheries Management Colin W. Clark Discusses the management of commercial marine fisheries and the relationship between the economic forces affecting the fishing industry and the biological factors that determine the production and supply of fish in the sea. Topics focus on methods of preventing overfishing and overcapitalization, economically effective and practical forms of regulation, management of developing fisheries, natural fluctuations of fish stocks, and complexities of marine ecosystems. 1985 (0 471-87394-2) 291 pp. Methods in Marine Zooplankton Ecology Makoto Omori and Tsutomu Ikeda Encompassing basic principles, procedures, and research problems, this book serves as a complete guide to current methods used in the study of marine zooplankton. The techniques are equally applicable to small organisms and to the larval stages of larger, commercially important organisms. Chapters start with a brief, but well-summarized introduction to zooplankton, followed by field sampling strategies and laboratory methods, and then conclude with estimates of productivity and analysis of community structure. Each method is described in detail, including a discussion of the problems inherent in using it. 1984 (0 471-80107-0) 322 pp.

This book was released on 2017-09-20 with total page 1048 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first comprehensive review of the current and future effects of climate change on the world’s fisheries and aquaculture operations The first book of its kind, Climate Change Impacts on Fisheries and Aquaculture explores the impacts of climate change on global fisheries resources and on marine aquaculture. It also offers expert suggestions on possible adaptations to reduce those impacts. The world's climate is changing more rapidly than scientists had envisioned just a few years ago, and the potential impact of climate change on world food production is quite alarming. Nowhere is the sense of alarm more keenly felt than among those who study the warming of the world's oceans. Evidence of the dire effects of climate change on fisheries and fish farming has now mounted to such an extent that the need for a book such as this has become urgent. A landmark publication devoted exclusively to how climate change is affecting and is likely to affect commercially vital fisheries and aquaculture operations globally, Climate Change Impacts on Fisheries and Aquaculture provides scientists and fishery managers with a summary of and reference point for information on the subject which has been gathered thus far. Covers an array of critical topics and assesses reviews of climate change impacts on fisheries and aquaculture from many countries, including Japan, Mexico, South Africa, Australia, Chile, US, UK, New Zealand, Pacific Islands, India and others Features chapters on the effects of climate change on pelagic species, cod, lobsters, plankton, macroalgae, seagrasses and coral reefs Reviews the spread of diseases, economic and social impacts, marine aquaculture and adaptation in aquaculture under climate change Includes special reports on the Antarctic Ocean, the Caribbean Sea, the Arctic Ocean and the Mediterranean Sea Extensive references throughout the book make this volume both a comprehensive text for general study and a reference/guide to further research for fisheries scientists, fisheries managers, aquaculture personnel, climate change specialists, aquatic invertebrate and vertebrate biologists, physiologists, marine biologists, economists, environmentalist biologists and planners.
