Book excerpt: Caribbean spiny lobster (Panulirus argus) is a heavily exploited seafood throughout its range and supports the primary fishery in The Bahamas. However, its long pelagic larval duration and, thus, potential for long-range dispersal increases the difficulty in determining the origins of local populations and complicates management. In recent years, the Bahamian fishery has transitioned to the use of condos (or casitas) as the primary fishing method. Condos are relatively inexpensive to construct and deploy, and it is estimated there are now over a million deposited throughout the Bahama banks. Collectively, these factors, coupled with an increased level of effort in the form of new fishers and more boats, have contributed to increased levels of competition for an already limited resource, further complicating the development of adequate and sustainable management strategies. The potential for human-induced changes to the ecosystem due to the proliferation of condos highlights the need for an interdisciplinary investigation of the fishery that takes into account both natural and anthropogenic impacts. This project utilizes an interdisciplinary approach that examines the biophysical forces that impact spiny lobster coupled with the chief human activities. Data from a biophysical model, a bioeconomic model, and surveys and interviews are used to help create a robust assessment of the fishery and aid in the proposal of viable management strategies. The integration of interdisciplinary methodologies provides an example of how these merged tools can help understand ecological processes while assisting management decisions. Simulations of larval dispersal for Bahamian spiny lobster populations indicate dispersal distances (or dispersal kernel) of 200-400 km, with a 25% probability of successful settlement. Surveys and semi-structured interviews of Bahamian fishers revealed five popular areas for condo placement. Further connectivity assessments of these locations indicate higher rates of settlement success for 4 sites. Two of these locations demonstrated a narrower dispersal kernel, suggesting self-recruitment. However, the 3 remaining locations appear to depend on subsidies from other spiny lobster populations throughout the Caribbean. These differences in connectivity suggest each location should be evaluated individually to determine spatially-dependent management actions, and to effectively develop and implement condo-related policies that will be supported by local communities. A bioeconomic analysis, completed by incorporating data on condo effort obtained through the surveys and interviews, revealed the fishery is operating beyond Open Access levels. The model revealed that the fishery has the potential to increase its profits if operated at the maximum economic yield. However, survey responses indicate fishers may be more amenable to a fishery managed towards the maximum sustainable yield, particularly if operating at MEY results in a drastic reduction of condo effort. This analysis revealed the necessity for additional management controls within the fishery, as well as filling the gaps that exist in the fishery data. An examination of the increased condo usage, and the implications of this use on how the fishers define, perceive, and adhere to access and property rights is achieved through a political ecology lens. This case is amenable to such an analysis due to the heavy interdependence of ecology and human factors throughout the fishery, allowing for an assessment of how the ecological, social, and economic elements interact to create and define the fishery, including the implications of this convergence on the overall management. Surveys and semi-structured interviews of Bahamian fishers and other stakeholders revealed many conflicting views about the fishery, particularly around ownership of the condos and the lobster within them. A further examination of the data highlighted the emergence of several political ecology themes within the fishery, as well as the importance of considering both internal factors, such as social pressures, local norms, and voluntary agreements, and external ones, including demand and market value defined by a global market, when determining how to sustain and successfully manage the fishery.

Download or read book California Spiny Lobster Panulirus Interruptus Movement Behavior and Habitat Use written by and published by . This book was released on 2010 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine protected areas (MPAs) are widely used to rebuild depleted populations for exploited species, but their effectiveness hinges on adequate knowledge of the factors dictating population dynamics for target organisms. Estimates of connectivity via larval dispersal often are included in MPA design, but movement patterns, habitat associations, and habitat-specific survival rates of juveniles and adults, which often are unknown, also will influence MPA effectiveness. California spiny lobsters (Panulirus interruptus Randall) are the target of intense commercial and recreational fishing in southern California, but we lack basic information about home range and habitat use of lobsters to determine if MPAs planned for the region will enhance abundance. Working within and outside of the La Jolla Ecological Reserve (LJER) in southern California, we (i) quantified lobster movement patterns and home ranges over short (nightly -- weekly) and long (1 -- 14 months) time scales using acoustic telemetry, (ii) surveyed lobsters to determine day and night habitat associations, and (iii) tethered lobsters to assess habitat-specific predation risk. Lobsters exhibited high site fidelity, proclivities for homing, and small home ranges (geometric mean of 651 m2 and 5,912 m2 per week based on 50% and 95% Kernel Utilization Distributions (KUDs), respectively) that encompassed only a fraction of a small MPA, even over periods of several months. Lobsters were strongly associated with rocky habitat during the day (when in shelters) but were associated with the red algae Plocamium cartilagineum at night (when feeding). Lobster relative survival rates were high across vegetated and unvegetated habitats at night, but lobsters were protected from predators by surfgrass (Phyllopsadix torreyi) habitat during the day. Our results highlight the need to consider how movement patterns vary over short and long time scales, and how patterns of habitat use may vary from day to night for nocturnally active species such as spiny lobsters when planning MPAs.

Available in PDF, EPUB and Kindle. Book excerpt: Although the ocean-and the resources within-seem limitless, there is clear evidence that human impacts such as overfishing, habitat destruction, and pollution disrupt marine ecosystems and threaten the long-term productivity of the seas. Declining yields in many fisheries and decay of treasured marine habitats, such as coral reefs, has heightened interest in establishing a comprehensive system of marine protected areas (MPAs)-areas designated for special protection to enhance the management of marine resources. Therefore, there is an urgent need to evaluate how MPAs can be employed in the United States and internationally as tools to support specific conservation needs of marine and coastal waters. Marine Protected Areas compares conventional management of marine resources with proposals to augment these management strategies with a system of protected areas. The volume argues that implementation of MPAs should be incremental and adaptive, through the design of areas not only to conserve resources, but also to help us learn how to manage marine species more effectively.

Available in PDF, EPUB and Kindle. Book excerpt: With the health of the world’s oceans threatened as never before, it is becoming increasingly apparent that Marine Protected Areas (MPAs) play a vitally important role in protecting marine and coastal habitats. Management of Marine Protected Areas: A Network Perspective draws on the results of a major EU-sponsored research project related to the establishment of networks of MPAs in the Mediterranean and Black Seas that transpired from February 2011 to January 2016. Featuring contributions by leading university- and national research institute-based scientists, chapters utilize the latest research data and developments in marine conservation policy to explore issues related to ways in which networks of MPAs may amplify the effectiveness and conservation benefits of individual areas within them. Topics addressed include the broader socio-economic impacts of MPAs in the Mediterranean and Black Seas; the use of Marine Spatial Planning (MSP) to resolve conflicts between marine resource use and protection; special protection measures under the EU’s Marine Strategy Framework Directive (MSFD); ecological value assessments in the Black Sea; the Ecosystem Approach (EA) for managing marine ecosystems; MPAs along Turkey’s Black Sea coast; MPAs and offshore wind farms; and managing and monitoring MPA networks within and between the Black and Mediterranean Seas. Timely and important, Management of Marine Protected Areas: A Network Perspective offers invaluable insights into the role of MPAs in preserving the welfare and long-term viability of our world’s oceans.

Download or read book The Larval Dispersal of California Marine Invertebrates written by Henry S. Carson and published by . This book was released on 2008 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measuring the exchange of larvae is fundamental to understanding the population dynamics of marine organisms and designing effective management and restoration strategies for them. Population connectivity in the sea has been difficult to measure directly due to the small size and high mortality of marine larvae and their vast potential dispersal area. In three separate studies I examined larval dispersal in three groups of invertebrates on the California coast. The first study estimated the dispersal potential of 501 southern California bight polychaete species using known or inferred life-history characteristics, and related this potential to the species' distributions. Increased potential to disperse was related to higher occurrence frequencies in samples collected from soft-sediment habitats on the Channel Island shelves, but not on southern California mainland shelves. Channel Island polychaetes had lower dispersal potentials than their mainland counterparts, which may make Channel Island marine reserves comparatively more effective at maintaining local reproduction and, as a consequence, biodiversity. The second study explored the use of trace-elemental fingerprinting techniques to measure dispersal directly. These techniques have been previously utilized on larvae that retain calcified structures through development, such as fish or molluscs. We explored the use of trace-elemental fingerprinting on larvae that lack such structures. We found fine-scale chemical variation in porcelain crab embryos at 16 sites along 175 kilometers of coastline. This variation could potentially be used as a site- or region-specific fingerprint to assign settled porcelain crab larvae back to their point of origin. The third study employed trace-elemental fingerprinting to track the larvae of the Olympia oyster among four estuaries in southern California. Settled larvae collected at eight sites in 2007 were assigned to one of three source regions by comparing the chemistry of the portion of their shell formed during brooding with brooded shells collected at the same sites. Significant larval exchange occurred among all three regions separated by as many as 75 kilometers of coastline. The majority of recruits to San Diego Bay and two north San Diego County lagoons were self-recruits, and these two regions produced the majority of recruits to Mission Bay
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.
Download or read book Lobsters Biology Fisheries and Aquaculture written by E. V. Radhakrishnan and published by Springer Nature. This book was released on 2019-11-28 with total page 683 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an important addition to the knowledge of lobster research. The book complements other books published on lobster research and management as it focuses on Indian lobster fisheries and aquaculture developments where there have been nearly 350 research papers and reports and 19 PhD awards. The book has 15 chapters written by international experts covering many aspects of the biology of a number of spiny and slipper lobster species occurring in India and world oceans with maps illustrating global distribution of spiny lobster families, genera and species. An updated taxonomy and checklist of marine lobsters, the status and management of lobster fisheries in India and Indian Ocean Rim countries and a review of aquaculture research in India and other major countries have also been presented. The book is timely as the 2nd International Indian Ocean Expedition (IIOE) is currently underway (2015-2020), 50 years after the original IIOE (1959-1965), with some of the original lobster research on the biology and distribution of phyllosoma larvae being undertaken on the plankton samples collected during the first IIOE. Many of the chapters are contributed by the authors from Central Marine Fisheries Research Institute (CMFRI), which has been collecting fishery and biological data on lobsters since 1950 when lobster fishing began on a subsistence scale, followed by some industrial fishing for lobsters in different parts of India. Unfortunately, the development of some of these lobster fisheries was followed by overfishing due to lack of enforcement of regulations. The book provides a valuable addition to our knowledge of the biology, fisheries and aquaculture of spiny and slipper lobsters.

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.
