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.
Download or read book Technical guidelines for scientific surveys in the Mediterranean and the Black Sea written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2020-05-01 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Mediterranean and the Black Sea, the assessment of demersal stocks mainly relies on scientific surveys (bottom and beam trawl) while the assessment of pelagic stocks is essentially based on acoustic surveys using acoustic techniques with mid-water trawling. These routine surveys-at-sea provide essential information, which in turn are crucial to fine-tune the assessments of the status of resources and to estimate more precisely indicators at the population and fish community levels. However, survey practices differ from one subregion to another, each approach having its own strengths and limitations. In addition, there is still a lack of large-scale standardized surveys aimed at analysing the diversity and distribution of the main demersal and pelagic species across the Mediterranean and the Black Sea. One way of tackling this issue is to carry out international scientific surveys covering the main demersal and pelagic stocks based on a common methodology. The methodology presented in this publication aims at supporting the planning and implementation of regional demersal (bottom and beam) trawl and pelagic acoustic surveys. It can be useful for the implementation of new surveys-at-sea in areas where demersal trawl and pelagic acoustic surveys are not regularly carried out. It can also contribute to increasing comparability between existing surveys thanks to the standardization of methods, sampling of catches and data recording and analysis. Finally, it represents a valuable tool to define minimum requirements towards sustainability and management objectives at the regional and subregional level.

Book excerpt: The forty-third session of the General Fisheries Commission for the Mediterranean (GFCM) and the tenth session of the Committee on Administration and Finance were attended by delegates of 19 contracting parties, as well as of three cooperating non-contracting parties and two non-contracting parties. Representatives from 13 intergovernmental and non-governmental organizations, the Food and Agriculture Organization of the United Nations and its regional projects, as well as the Bureaus of the Commission and its subsidiary bodies, were also in attendance. During the session, progress in activities related to fisheries, aquaculture, compliance and other strategic activities was reviewed. Moreover, the outcomes of the second GFCM performance review were commented. In relation to the management of fisheries and aquaculture in the GFCM area of application, eight binding recommendations were adopted, dealing with the following issues: the use of anchored fish aggregating devices in common dolphinfish fisheries in the Mediterranean Sea, information on access agreements in the GFCM area of application, the establishment of a list of vessels presumed to have carried out illegal, unreported and unregulated fishing in the GFCM area of application, the sustainable exploitation of blackspot seabream in the Alboran Sea and red coral in the Mediterranean Sea, multiannual management plans for turbot fisheries in the Black Sea and sustainable demersal fisheries in the Adriatic Sea, and management measures for sustainable trawl fisheries targeting giant red shrimp and blue and red shrimp in the Strait of Sicily. Furthermore, the Commission discussed issues related to the mandate of the GFCM Executive Secretary.

Download or read book Handbook on fish age determination a Mediterranean experience written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-05-31 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook provides guidance on methods for use in fish ageing studies. Fish age, among other biological parameters, is one of the most relevant pieces of data to attain sustainable exploitation levels of fishery resources. Indeed, most analytical methods used in stock assessment require knowledge of demographic structure according to age of stocks, as well as to recruitment, growth, maturity, natural mortality, etc., which are strictly linked to information on age and age structure. The handbook was put together to deal with identified gaps – which affect both the precision and the accuracy of estimations – regarding ageing schemes, criteria and methodologies used in preparing calcified structures. It focuses on the general principles that underpin age analysis (assignment of birth date, preparation methods, aging scheme reading and identification of true and false rings). Crucially, it aims to contribute to the establishment of common analysis methods, which can enable better calibration across the diverse institutes involved, thereby improving the quality and reliability of results.

Marine Resources Service and published by Food & Agriculture Org.. This book was released on 1994 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document provides a review, commentary and tabulations of the main trends that have occurred in exploitation of fisheries resources since the 1970s, largely as they are reflected in the FAO database on fishery landings, supplemented with selected information from the fishery literature. Reviews were prepared separately for the 15 main areas into which FAO divides the world's oceans for statistical purposes. They are then compared from a global perspective to reveal relative trends by species and areas, which are highlighted. Several special topics are reviewed, including tuna and tuna-like species, whales and dolphins, and environmental issues in fisheries.
Download or read book The living marine resources of the Eastern Central Atlantic Volume 4 Bony fishes part 2 Perciformes written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-11-15 with total page 820 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multivolume field guide covers the species of interest to fisheries of the major marine resource groups exploited in the Eastern Central Atlantic. The area of coverage includes FAO fishing area 34 and part of 47. The marine resource groups included are bivalves, gastropods, chitons, cephalopods, stomatopods, shrimps, lobsters, crabs, hagfishes, sharks, batoid fishes, chimaeras, bony fishes and sea turtles. The introductory chapter outlines the environmental, ecological, and biogeographical factors influencing the marine biota, and the basic components of the fisheries in the Eastern Central Atlantic. Within the field guide, the sections on the re source groups are arranged phylogenetically according to higher taxonomic levels such as class, order, and family. Each resource group is introduced by general re marks on the group, an illustrated section on technical terms and measurements, and a key or guide to orders or families. Each family generally has an account summarizing family diagnostic characters, bi o logical and fisheries in formation, notes on similar families occur ring in the area, a key to species, a check list of species, and a short list of relevant literature. Families that are less important to fisheries include an abbreviated family account and no de tailed species in formation. Species in the important families are treated in detail (arranged alphabetically by genus and species) and include the species name, frequent synonyms and names of similar specie s, an illustration, FAO common name(s), diagnostic characters, biology and fisheries in formation, notes on geo graphical distribution, and a distribution map. For less important species, abbreviated accounts are used. Generally, this includes the species name, FAO common name(s), an illustration, a distribution map, and notes on biology, fisheries, and distribution. Each volume concludes with its own index of scientific and common names.

Download or read book Fish atlas of the Celtic Sea North Sea and Baltic Sea written by Henk J.L. Heessen and published by BRILL. This book was released on 2023-09-14 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: The atlas presents a unique set of abundance data to describe the spatial, depth, size, and temporal distribution of demersal and pelagic fish species over an extensive marine area, together with accounts of their biology. A large number of pictures, graphs and distribution maps illustrate the text. By largely avoiding - or at least explaining - scientific terms and providing extensive references, the book should be useful for both laymen and scientists. The quantitative information on some 200 fish taxa is derived from 72,000 stations fished by research vessels during the period 1977-2013. The area covers the northwest European shelf from west of Ireland to the central Baltic Sea and from Brittany to the Shetlands. Although the surveys extend beyond the shelf edge, only taxa reported at least once in waters less than 200 m are included. Typical deep-water species and typical fresh-water species are excluded. We hope this publication will contribute to gaining a better understanding of the ocean ecosystems.
