Book Synopsis The Effect of Temperature on the Supply and Demand for the American Lobster (Homarus Americanus) in the State of Maine by : Gaby E. Carpenter
Download or read book The Effect of Temperature on the Supply and Demand for the American Lobster (Homarus Americanus) in the State of Maine written by Gaby E. Carpenter and published by . This book was released on 2016 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Gulf of Maine (GOM) American lobster (Homarus americanus) stock accounts for 90% of the U.S. American lobster landings. This makes it an extremely valuable and important fishery on a national scale, but also to the state of Maine. In the past decade, the fishery has experienced rapid fluctuation in landings and price due to anthropogenic influences of the water temperature in the GOM. Given the economic importance of the fishery, it is important to understand the future impacts of climate change on the availability of lobster and economic consequences of these shifts. A bio-economic model is used in the analysis of the supply and demand to determine the effect of warmer ocean waters on the American lobster. The current supply and demand for the American lobster is estimated using an ordinary least squares regression. The estimated supply model is simulated under a higher temperature scenario and fed into the demand model to simulate a new lobster price. Overall, it was projected that the higher temperature scenario results in a 9% increase in lobster landings and 8% decrease in the price per pound of lobsters. While this is a preliminary study of an integrated supply and demand model that incorporates the impacts of climate change, the results are robust. This motivates future studies to understand the implications of higher ocean temperature on lobsters and the large economy in the state of Maine that rely on the resource.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Water temperature influences basic life history traits of the American lobster (Homarus americanus) such as survival, growth and reproduction. Yet, relatively little is known about the effects of water temperature on the immune response of H. americanus. White spot syndrome virus (WSSV) is currently one of the largest impediments to the shrimp aquaculture industry worldwide. The World Organization for Animal Health (Office International de Epizootic; OIE) lists WSSV as a notifiable disease with the potential to infect all crustacean decapods. This project investigates the constraints imposed by a range of temperatures (10 oC, 15 oC, 17.5 oC, 20 oC) on the clinical, tissue and molecular immune responses of H. americanus experimentally infected with WSSV. Haemocyte concentration and qPCR testing of haemolymph were used to monitor the host's clinical response over time and to determine presence of viral infection, respectively. A decrease in clinical condition of H. americanus was observed at 17.5 oC and 20 oC but not at 10 oC and 15 oC. WSSV-qPCR revealed viral amplification was associated with higher ambient temperature. A combination of light and electron microscopy, as well as qPCR testing of various tissues was used to elucidate changes within infected H. americanus at the various temperatures. Of the 11 host tissues examined, hypertrophied nuclei (indicative of WSSV infection) were most easily identifiable within the antennal gland and intestine of infected animals at warmer temperatures (17.5 oC and 20 oC). At colder temperatures (10 oC) no WSSV associated histopathological changes were identified in any of the examined tissues. Electron microscopy was used to explore the general ultrastructure of the antennal gland and the confirmed presence of WSSV rod-shaped and enveloped virions. In infected animals the two main regions of the antennal gland, the coelomosac and labyrinth, contained randomly distributed infected nuclei with marginated host chromatin and WSSV virions in various stages of replication. In marine decapods, the antennal gland is involved in osmoregulation and excretion suggesting that the antennal gland may be a preferred site for WSSV viral replication and inclusion within the excretory product. Lastly, a lobster specific microarray was used to monitor transcriptomic changes across 14,592 genes during viral infection at the different temperatures. Using one-way ANOVA analyses, a total of 717 genes were identified as significantly differentially expressed between infected and control H. americanus at the various temperatures. Differentially expressed genes included, ribosomal proteins (L27a, L13, L11, and L39), mitogen-activated protein kinase organizer 1, prolyl-4-hydroxylase-alpha, laminin subunit gamma-3, short-chain dehydrogenase and acute phase serum amyloid A. Microarray results were verified using RT-qPCR. Clinical, tissue and molecular immune results from this study provide a thorough assessment of the impact of temperature and WSSV in H. americanus. The use of a range of approaches and experimental temperatures is critical for broadening our understanding of how temperature influences host pathogen interactions in the economically important American lobster H. americanus.
Book Synopsis Migration and Dispersion of Tagged American Lobsters, Homarus Americanus, on the Southern New England Continental Shelf by : Joseph R. Uzmann
Download or read book Migration and Dispersion of Tagged American Lobsters, Homarus Americanus, on the Southern New England Continental Shelf written by Joseph R. Uzmann and published by . 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 2018-06-18 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change poses many challenges that affect society and the natural world. With these challenges, however, come opportunities to respond. By taking steps to adapt to and mitigate climate change, the risks to society and the impacts of continued climate change can be lessened. The National Climate Assessment, coordinated by the U.S. Global Change Research Program, is a mandated report intended to inform response decisions. Required to be developed every four years, these reports provide the most comprehensive and up-to-date evaluation of climate change impacts available for the United States, making them a unique and important climate change document. The draft Fourth National Climate Assessment (NCA4) report reviewed here addresses a wide range of topics of high importance to the United States and society more broadly, extending from human health and community well-being, to the built environment, to businesses and economies, to ecosystems and natural resources. This report evaluates the draft NCA4 to determine if it meets the requirements of the federal mandate, whether it provides accurate information grounded in the scientific literature, and whether it effectively communicates climate science, impacts, and responses for general audiences including the public, decision makers, and other stakeholders.
