Book (series)Monitoring discards in Mediterranean and Black Sea fisheries: methodology for data collection 2019
Also available in:
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. -
Brochure, flyer, fact-sheetBrief - Collecting data on the incidental catch of vulnerable species in Mediterranean and Black Sea fisheries 2021
Also available in:
No results found.This brief aims at providing policy makers and other interested parties with an overview of data collection for the monitoring of the incidental catch of vulnerable species (sharks and rays, seabirds, sea turtles and marine mammals) in fisheries. It higlights and summarizes the key aspects illustrated in the protocol developed by the General Fisheries Commission for the Mediterranean on Monitoring the incidental catch of vulnerable species in the Mediterranean and the Black Sea - Methodology for data collection. 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 therefore necessary to improve knowledge on the issue and to subsequently support the identification of potential mitigation methods and tools, and relevant management measures. This leaftlet provides information to facilitate the development and implementation of an efficient, standardized data collection and monitoring system for vulnerable species encountered in the region. -
BookletThe State of Mediterranean and Black Sea Fisheries 2020 - At a glance 2020The State of Mediterranean and Black Sea Fisheries – At a glance is based on the GFCM flagship biennial report The State of Mediterranean and Black Sea Fisheries. The full-length publication is the most comprehensive overview of regional and subregional trends in fisheries currently available, and the 2020 edition contains more data and information than ever before. The State of Mediterranean and Black Sea Fisheries – At a glance offers a summary of this material, giving the general reader a swift and simple overview of its main themes and findings. The report takes a deep dive into the composition of the regional fishing fleet, capture fisheries production statistics and the current state of fishery resources, including bycatch and vulnerable species. Notably, it provides the most detailed picture yet of the vital small-scale sector, both in terms of its activities at sea and in the broader socioeconomic context of coastal communities across the region. Long-term management measures are also investigated, highlighting the ways in which the GFCM is working to make key fisheries in the region sustainable for the future. The State of Mediterranean and Black Sea Fisheries – At a glance examines findings on all these subjects, summarizing important data and explaining notable developments. When looking for the latest and most reliable information on Mediterranean and Black Sea fisheries and the communities they support, this is the place to start.
