Download or read book Sharks in Danger written by Rachel Cunningham-Day and published by Dissertation.com. This book was released on 2001 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the current status of, and threats to, shark populations globally with special reference to the basking shark and the great white shark. This book outlines why sharks are a valuable resource, identifies threats to sharks and where they occur and reviews what we need to know about sharks in order to protect them. Fisheries management procedures are investigated to target areas requiring future research and implementation. Conservation initiatives, legislation, and international agreements are reviewed and future measures suggested. Case histories on the basking shark and the great white shark detail threats specific to these species and identify research and management requirements. Sharks are a valuable resource both directly through shark watching trips, medical research and commercial and recreational fisheries, and indirectly through the selection pressure they exert on our teleost fisheries, the part they play in maintaining the ecology of the ocean and their intrinsic scientific value. Identifiable threats to sharks are recreational and commercial overfishing and environmental degradation rendered by man such as development of nursery and mating zones and disturbance of the marine environment through netting and trawling. Particular threats to sharks worldwide are the exploitative fin and cartilage trades. Information required for the sustainable management of sharks include life history episodes such as reproductive rates, vulnerable life stages, population dynamics and spatial and temporal distribution. An indepth analysis of white sharks and basking sharks reveal similarities in their reproductive strategies such that both species will follow similar management practices. In reviewing fishery management practises it was found that sustainable management plans must be based upon reproductive rates requiring knowledge of life histories. Life history information is often required for legislative protection such that extremely rare species cannot be considered. Protective legislation should be targeted towards individual species and vulnerable life stages, particularly nursery and mating zones. Further legislation should be enacted to improve current knowledge through data collection.

Download or read book Rays of the World written by Peter Last and published by CSIRO PUBLISHING. This book was released on 2016-12 with total page 801 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rays are among the largest fishes and evolved from shark-like ancestors nearly 200 million years ago. They share with sharks many life history traits: all species are carnivores or scavengers; all reproduce by internal fertilisation; and all have similar morphological and anatomical characteristics, such as skeletons built of cartilage. Rays of the World is the first complete pictorial atlas of the world’s ray fauna and includes information on many species only recently discovered by scientists while undertaking research for the book. It includes all 26 families and 633 valid named species of rays, but additional undescribed species exist for many groups. Rays of the World features a unique collection of paintings of all living species by Australian natural history artist Lindsay Marshall, compiled as part of a multinational research initiative, the Chondrichthyan Tree of Life Project. Images sourced from around the planet were used by the artist to illustrate the fauna. This comprehensive overview of the world’s ray fauna summarises information such as general identifying features and distributional information about these iconic, but surprisingly poorly known, fishes. It will enable readers to gain a better understanding of the rich diversity of rays and promote wider public interest in the group. Rays of the World is an ideal reference for a wide range of readers, including conservationists, fishery managers, scientists, fishers, divers, students and book collectors.

Available in PDF, EPUB and Kindle. Book excerpt: The Darwin Elasmobranch Biodiversity Conservation and Management project in Sabah held a three-day international seminar that included a one-day workshop in order to highlight freshwater and coastal elasmobranch conservation issues in the region and worldwide, to disseminate the result of the project to other Malaysian states and countries, and to raise awareness of the importance of considering aspects of elasmobranch biodiversity in the context of nature conservation, commercial fisheries management, and for subsistence fishing communities. These proceedings contain numerous peer-reviewed papers originally presented at the seminar, which cover a wide range of topics, with particular reference to species from freshwater and estuarine habitats. The workshop served to develop recommendations concerning the future prospects of elasmobranch fisheries, biodiversity, conservation and management. This paper records those conclusions, which highlight the importance of elasmobranchs as top marine predators and keystone species, noting that permanent damage to shark and ray populations are likely to have serious and unexpected negative consequences for commercial and subsistence yields of other important fish stocks.

This book was released on 2011-10-01 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sulu-Sulawesi Marine Ecoregion (SSME), as the apex of the Coral Triangle, is considered the center of the center of marine biodiversity where the highest number of colorful reef and marine fishes, various sizes of corals and shells, myriad shapes of algae, and protective mangrove forests are found. The SSME's marine aquarium is not only a delightful lure for tourists but is also the source of food and a natural capital for livelihoods among coastal communities. To address threats to SSME's diversity and productivity, an ecoregion conservation plan was forged collaboratively by Indonesia, Malaysia, and the Philippines in 2004. As the management framework to address threats to its diversity and productivity, the SSME Ecoregion Conservation Plan has spurred the development of three comprehensive action plans for 2010-2012. These plans are implemented by the subcommittees on Migratory and Threatened Species, Marine Protected Areas and Networks, and Sustainable Fisheries, and guided by the SSME's Tri-National Committee. This publication includes business plans and cost estimates to implement the three action plans---providing useful guide on costs and activities for governments, prospective donors, and investors; valuable information from cost-benefit analyses; and lessons learned from past conservation efforts.

Download or read book Sharks and Their Relatives written by Merry Camhi and published by IUCN. This book was released on 1998 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sharks and their relatives, the rays and chimaeras, are the diverse group of cartilaginous fishes that have evolved over 400 million years. Historically considered of low economic value to large-scale fisheries, today many of these fishes have become the target of directed commercial and recreational fisheries around the world, and they are increasingly taken in the by-catch of fisheries targeting other species. This report emphasizes the widely-acknowledged need to improve shark fishery monitoring, expand biological research and take management action. It serves as an introduction to the ecology, status and conservation of the sharks and their relatives for a general audience. Shark fisheries can only be managed sustainably, and shark populations remain viable, with the introduction of new conservation and management initiatives.

Download or read book Sharks: Conservation, Governance and Management written by Erika J. Techera and published by Routledge. This book was released on 2014-06-05 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: The key aim of this book is to explore the global conservation and management of sharks. There has been a rapid decline in populations of many shark species, while new science has emerged of the critical role they play in marine ecosystems. However, the authors show that conservation law and policy have been slow to develop, with only a small number of iconic species being protected worldwide. The increase in fishing impact – primarily through shark finning and by-catch - has led to shark conservation receiving greater international attention in recent years. The book explores our current knowledge and status of the law and science in relation to sharks with a particular focus on improving frameworks for their conservation and management. Recent trends are analysed, including shark finning bans that have been put in place in several countries, the widening number of nations establishing shark sanctuaries and the growth of shark-based tourism. The efficacy of current listing processes for endangered species and fisheries regulations is also examined. Tourism is explored as an alternative to fishing and the risks and impacts associated with this industry are analysed. Contributors include leading authorities from universities and conservation organizations in North America, Europe and Australia. A common theme is to emphasise the importance of collaborative governance between various interest groups and the need for inter-disciplinary research and management approaches that are necessary to address the decline in sharks.

Download or read book Incidental catch of vulnerable species in Mediterranean and Black Sea fisheries – A review written by Carpentieri, P., Nastasi, A., Sessa, M., Srour, A. (eds.) and published by Food & Agriculture Org.. This book was released on 2021-06-28 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bycatch – a term widely used to refer to part of the catch unintentionally caught during a fishing operation, in addition to target species, and consisting of the discards and incidental catch of vulnerable species – is considered one of the most important threats to the profitability and sustainability of fisheries, as well as to the conservation of the marine environment and ecosystems. Understanding the bycatch issue and adopting effective measures in order to reduce bycatch rates are essential steps towards minimizing the impacts on vulnerable species and ensuring both a sustainable fisheries sector and healthy seas. In the Mediterranean and the Black Sea, the incidental catch of vulnerable species – namely seabirds, sea turtles, elasmobranchs, marine mammals and macrobenthic invertebrates – represents one of several challenges for the industrial, semi-industrial and small-scale fisheries that coexist in the region, as well as for the diverse and sensitive ecosystems impacted. Typically, data on this issue have been collected in an opportunistic manner and in ways that make comparisons difficult. The annual absolute values of incidental catch of vulnerable species are not available: studies cover only a small portion of the total fishing activity and often present important knowledge gaps for many types of fishing gear, countries and/or subregions, as well as on temporal scales, for example, to establish reliable baselines. The result is that little is known of the scope of the problem, despite incidental catch being a significant pressure on the populations of vulnerable species, as well as a concern for fishers.This regional review is an attempt to compile, in one single document, all available data and historical records on the incidental catch of vulnerable species in the Mediterranean and Black Sea fisheries, obtained from existing literature, databases and other grey sources, and collated in a standardized and comparable way. The main objective is to provide comprehensive baseline information, earmark the main data gaps, as well as identify the most impacting types of fishing gear by taxonomic group. This work is a reminder of the importance of standardized data collection and the need to have baseline information in order to support decision-making in the identification of appropriate bycatch mitigation techniques, thus enabling analysis of their effectiveness and comparison over time and space, as well as facilitating the implementation of relevant conservation and/or management measures at the national, subregional and regional levels.
