Available in PDF, EPUB and Kindle. Book excerpt: "Maturity is one of the most relevant biological parameters used in stock assessment programmes. Indeed, the macroscopic stage of gonadal development is an essential feature in estimating the maturity ogive and spawning stock biomass (SSB). It is also useful for determining the spawning season of a species and for monitoring long-term changes in the spawning cycle, as well as for many other research needs related to the biology of fish. In current data collection programmes carried out in the Mediterranean which cover extensive samplings of maturity stages, some specific technical aspects have not always been taken into consideration, and collected data cannot reach the required precision levels. Also, the coding schemes in use and the uncertainty in the interpretation of particular stages can give rise to misinterpretations of the actual maturity stage leading to inaccurate spawning stock biomass estimations. Several stock assessments are therefore based on time-invariant maturity ogives and only partially cover the spatial distribution of the stocks. Hence, on several occasions, the need has been expressed to improve the identification of the macroscopic maturity stages through a standardization of operational procedures and terminology. One of the solutions for overcoming these problems was to formalize an atlas of the macroscopic and histological maturity stages of the main species of commercial interest in the Mediterranean. In this context, this atlas aims to develop sound approaches to maturity sampling for a wide range of species, based on an accurate and precise determination of the different maturity stages. It includes macroscopic photos of gonads belonging to the main species, and for some of them, a validation-based histological analysis is also presented. The systematic categories investigated in the atlas are bony fish, cartilaginous fish, both oviparous and viviparous, crustaceans and cephalopods."--Publisher's description

This book was released on 2019-02-19 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume includes all the abstracts of the keynotes, oral contributions and posters presented by participants on the occasion of the Forum on Fisheries Science in the Mediterranean and the Black Sea (Fish Forum 2018). Organized by the GFCM at FAO headquarters, Rome, Italy, from 10 to 14 December 2018, in collaboration with technical partners, the Fish Forum 2018 is a first-of-the-kind event gathering scientists, researchers, engineers, academics, practitioners, managers and decision-makers from around the world to discuss and share knowledge on the latest developments in fisheries science. The material contained in this book of abstracts stems from the contributions received from participants and selected by an international scientific committee based on their technical quality and relevance. The abstracts are subdivided according to the three main themes of the Fish Forum 2018: Better science for better advice; Healthy seas and sustainable fisheries; and Economic analysis and technology for societal benefit. Each theme is introduced by a keynote presentation, followed by oral presentations and posters. These documents form the basis of the discussions held during parallel sessions and poster sessions of the Fish Forum 2018.

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.

Book Synopsis Technical guidelines for scientific surveys in the Mediterranean and the Black Sea by : Food and Agriculture Organization of the United Nations
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 Synopsis Fish atlas of the Celtic Sea, North Sea, and Baltic Sea by : Henk J.L. Heessen
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.

Download or read book Fish Reproductive Biology written by Tore Jakobsen and published by John Wiley & Sons. This book was released on 2016-03-21 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish recruitment is a key process for maintaining sustainable fish populations. In the marine environment, fish recruitment is carried out in many different ways, all of which have different life history strategies. The objective of this book is to argue for greater linkages between basic and applied research on fisheries recruitment, and assessment and management of exploited fish stocks. Following an introductory chapter, this second edition of Fish Reproductive Biology is organized into 3 main sections: Biology, Population Dynamics and Recruitment Information Critical to Successful Assessment and Management Incorporation of Reproductive Biology and Recruitment Considerations into Management Advice and Strategies The authors collectively bring a wide range of diverse experience in areas of reproductive biology, fisheries oceanography, stock assessment, and management. Fully updated throughout, the book will be of great interest to a wide audience. It is useful as a textbook in graduate and undergraduate courses in fisheries biology, fisheries science, and fisheries resource management and will provide vital information for fish biologists, fisheries scientists and managers.

Book Synopsis Non-indigenous species in the Mediterranean and the Black Sea by : Food and Agriculture Organization of the United Nations
Download or read book Non-indigenous species 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 2021-07-29 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent decades have seen significant changes in the biota of the Mediterranean and the Black Sea due to the introduction of non-indigenous species. Reliable scientific data on the dynamics of their distribution and abundance are essential to understand their ecological and economic effects. This review – in addition to providing images and descriptions of relevant species to aid in identification – presents a unique historical and regional perspective on these species’ impacts, based on many years’ worth of research. The Black Sea’s primary invaders come from the Mediterranean. Species like the comb jelly Mnemiopsis leidyi have caused major declines in biodiversity in the region by crippling key segments of the food chain. Similar results have been noted in the Marmara Sea, a crucial water exchange point located between the Aegean Sea and the Black Sea. Infiltration into the Mediterranean comes from both the east and west – with Lessepsian species passing through the Suez Canal and fish and invertebrate species originating from the Atlantic expanding their ranges. As of the publication of this review, over 900 non-indigenous species have been reported in the Mediterranean and almost 300 in the Black Sea, with these numbers expected to rise in the future. Numerous Lessepsian fishes are commercially relevant and have been absorbed into local markets, particularly in the eastern Mediterranean region. While these species are targeted through various fishing techniques, many others are simply discarded due to a lack of value and there are even some, such as lionfishes, pufferfishes and several species of jellyfishes, that present immediate dangers to human health. Stewardship of native species, regional cooperation on the enforcement of legal measures, increased public awareness and the creation of marine protected areas are thus essential to minimize and reduce the impacts of non-indigenous species both in the Mediterranean and the Black Sea.
