Book Synopsis Incidental catch of vulnerable species in Mediterranean and Black Sea fisheries – A review by : Carpentieri, P., Nastasi, A., Sessa, M., Srour, A. (eds.)
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.

This book was released on 2020-12-14 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This third edition of the State of Mediterranean and Black Sea Fisheries provides a comprehensive overview of the status of fisheries in the region, looking at their main features and trends, in order to better inform their management and better examine current and future challenges that they will face in the near future. The aim of this report is to produce a document that could provide useful analysis and direction for decision-making and future action. In this respect, this publication also represents a convenient source of information for the FAO Committee on Fisheries and offers a practical complement to the data provided in the State of World Fisheries and Aquaculture published by the FAO Fisheries and Aquaculture Department. This volume includes seven chapters divided into two sections: a first part on the status and trends of different aspects of Mediterranean and Black Sea fisheries, including fleet, catches, socio-economic variables and bycatch, and a second part that focuses on the management of Mediterranean and Black Sea fisheries, including an overview on small-scale fisheries. This report is based to a large extent on the most up-to-date data available submitted by GFCM contracting and cooperating non-contracting parties, including information on stock status, national catches, fleet and socio-economic information up to 2018. It is also complemented with information from other sources.

Book Synopsis The State of Mediterranean and Black Sea Fisheries 2018 by : Food and Agriculture Organization of the United Nations
Download or read book The State of Mediterranean and Black Sea Fisheries 2018 written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-01-17 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2018 edition of The State of Mediterranean and Black Sea Fisheries (SoMFi 2018), the flagship publication of the GFCM, provides a comprehensive overview of regional and subregional trends in Mediterranean and Black Sea fisheries. Bringing together data and indicators submitted by GFCM contracting parties and cooperating non- contracting parties on stock status, national catches, fleet and socio-economic aspects as well as information obtained from other sources, SoMFi 2018 aims to provide objective, reliable and up-to-date information to a wide audience and support decision-making in fisheries. SoMFi 2018 is divided into eight chapters. The first analyses the current composition of the fishing fleet, including information on fleet capacity, vessel types and age classes. Next comes a detailed breakdown of overall capture fishery production with comparisons of the latest figures to data from previous years, highlighting significant changes and trends. The report then looks at what this means for regional economies and for the livelihoods of the people who depend on the fisheries sector. As small-scale fisheries make up a large majority of Mediterranean and Black Sea fisheries, they receive special focus. SoMFi 2018 also provides the most detailed assessment yet of the state of fishery resources in the region. It shows the current status of the stocks, including those most at risk from overfishing, and looks at related issues like discards and incidental catches of vulnerable species. The report then highlights GFCM’s strategic efforts to build long-term sustainability, as it works with its stakeholders to sustainably manage fisheries and improve coastal livelihoods across the region. Finally, SoMFi 2018 concludes with an overview of the important role fisheries have to play in achieving the United Nations Sustainable Development Goals, maintaining healthy ecosystems and productive fisheries.

Book Synopsis Monitoring discards in Mediterranean and Black Sea fisheries: methodology for data collection by : Food and Agriculture Organization of the United Nations
Download or read book Monitoring discards in Mediterranean and Black Sea fisheries: methodology for data collection written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-09-03 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discards – the part of the catch that is not retained on board, which may include target species or any other (commercial and non-commercial) species that are returned at sea dead or alive – usually result in a reduction of harvesting opportunities and may have negative consequences on the stocks, ecosystems and the marine environment. In the Mediterranean and the Black Sea, studies on discards only cover a small portion of the total fishing activities and discard rates are often poorly estimated or totally unknown. Information is lacking for many types of fishing gear, countries and GFCM subregions, and most available studies only cover relatively short periods and small areas. Discards therefore represent a major source of uncertainty about the actual fishing mortality rates of stocks. These knowledge gaps highlight the need to expand discard monitoring programmes and standardize practices, so to assess discards appropriately and address their important impacts. This publication and the methodology discussed herein aim to provide a framework for the development and implementation of an efficient, standardized data collection and monitoring system for discards through on-board observations, questionnaires at landing sites and self-sampling activities. It ensures minimum common standards for the collection of discards data and allows for repeatability and comparisons among fisheries across the region, thus offering a harmonized basis of knowledge, information and evidence for decision-making.

This book was released on 2019-09-03 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bycatch – a term widely used to refer to the part of catch unintentionally captured during a fishing operation, in addition to target species, and consisting of discards and incidental catches 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. In the Mediterranean, studies on the incidental catch of vulnerable species cover only a small portion of the total fishing activity. In addition, there are several important knowledge gaps for many types of fishing gear, and several countries and/or subregions, as well as on temporal scales, and only a few measures are in place that address the protection of vulnerable species. Monitoring programmes and surveys on incidental catches, which follow a harmonized methodology allowing for results to be compared across subregions, are necessary to improve knowledge on the issue and to subsequently support the identification of potential mitigation methods and tools, and relevant management measures. This publication and the methodology contained herein aim to provide a framework for the development and implementation of an efficient, standardized data collection and monitoring system for all vulnerable species encountered in the Mediterranean and the Black Sea, namely elasmobranchs, marine mammals, seabirds, sea turtles, and macrobenthic invertebrates.

Book Synopsis Chondrichthyes by : Luis Fernando Rodrigues-Filho
Download or read book Chondrichthyes written by Luis Fernando Rodrigues-Filho and published by BoD – Books on Demand. This book was released on 2017-12-20 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chondrichthyes are a group of cartilaginous fish, where we have sharks, rays, and chimeras as members. This group plays an important role in aquatic ecology, as they act as predators throughout the food chain (e.g., sharks). However, many populations of Chondrichthyes are threatened by several factors (increased direct fishing, high mortality rate as accompanying fauna, marine pollution, habitat destruction, etc.). These declines are evident in many parts of the world and have come to the attention of scientists, conservation organizations, the media, and the general public. Fisheries legislation regulating international fisheries markets has been amended to provide greater protection for this group along with other species of fish. However, little is known about these species, which reinforces the importance of studies in order to have a better understanding of the elasmobranch stocks, as well as to identify the influences of the anthropic action of fishing. In response to knowledge on the low sustainability of cartilaginous fish fisheries on a global scale, FAO has developed an international plan of action for the management and conservation of these fish, with the aim of developing and implementing national plans of action to ensure management and conservation of these stocks, having as main recommendation the collection of information about the Chondrichthyes, especially the sharks. Even so, this group is little known in terms of biodiversity, ecology, behavior, and a host of other characteristics relevant to this taxon, which is very worrying. Chondrichthyes - Multidisciplinary Approach attempts to portray to the readers up-to-date information on Chondrichthyes to promote an overview of the current taxon, serving as an indispensable source of access to more accurate and detailed information on shark rays and chimeras.
Book Synopsis Elasmobranch Biodiversity, Conservation and Management by : Sarah L. Fowler
Download or read book Elasmobranch Biodiversity, Conservation and Management written by Sarah L. Fowler and published by IUCN. This book was released on 2002 with total page 282 pages. 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.
