This book was released on 2022-04-21 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine recreational fishing is a popular activity enjoyed by more than 9 million Americans annually and is a driver of the American ocean-or blue-economy. To ensure that fish populations are not overexploited, the NOAA Fisheries' Marine Recreational Information Program (MRIP) monitors recreational catch through a variety of in-person, telephone, mail-in, and other surveys. NOAA Fisheries' management of recreational catch also must take into account annual catch limits (ACLs) established to prevent overfishing for all managed species in federal waters. While MRIP has worked to improve recreational catch surveys over the past decade, the surveys were never designed to meet the demands of in-season management of ACLs. In some cases, estimates of harvest have triggered accountability measures such as early season closures and reductions in future recreational ACLs, which have been a source of contention with the recreational fishing community. This report presents approaches for optimizing MRIP data and complementary data for in-season management and considers alternatives for managing recreational fisheries with ACLs to better serve both social and economic management objectives.

Book Synopsis Guidelines for the Routine Collection of Capture Fishery Data by : Food and Agriculture Organization of the United Nations
Download or read book Guidelines for the Routine Collection of Capture Fishery Data written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 1999 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: "These guidelines aim to help those who design routine data collection programmes, focusing on the relationship between typical questions asked by policy-makers and managers, and the data required for providing reliable answers. Fisheries policy and management objectives, particularly under the precautionary approach, need to be based upon analyses of reliable data. Data are needed to make rational decisions, evaluate the fisheries performance in relation to management activities and fulfil regional requirements. These objectives are achieved using fishery performance indicators. Indicators are used to measure the state of the resource, the performance of fishing controls, economic efficiency, socio-economic performance and social continuity. The primary factor in choosing what data to collect is the link between the necessary operational, biological, economic and socio-cultural indicators and their associated variables. The way in which different data variables are collected needs tobe tailored to the structure of the fishery. The strategy will be strongly influenced by the budget and personnel available, and the degree to which fishers and others co-operate. The programme must identify which variables should be collected through complete enumeration and which can be sampled. Collection methods are influenced by the variable itself, the strategy, collection point and the skill of the enumerator. Once collected, fishery data must be stored securely, but made easily available for analysis, which is achieved through a computer-based data management system, following the basic data processing principles. The implementation of a data collection programme should follow a normal project cycle, developing a new legal and institutional framework as appropriate"--Abstract.
Book Synopsis Manual on Sample-based Data Collection for Fisheries Assessment by : Per Sparre
Download or read book Manual on Sample-based Data Collection for Fisheries Assessment written by Per Sparre and published by Food & Agriculture Org.. This book was released on 2000 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual deals with the practical implementation of a routine data collection programme. The data collection programme is developed through a top-down approach, from the identification of the objectives down to the practical recording and management of data obtained from the fishery. The issues are dealth with both through detailed discussion and by using simple examples. The examples are mostly based on situations in tropical fisheries, and in particular, experience has been drawn from developing a data collection programme in Viet Nam. The main questions addressed i n the manual are which fisheries data to collect, where and when to collect them. Only data from commercial marine capture fisheries are considered. The methodologies used are mainly appropriate for a tropical, developing county, with many small (artisanal) vessels and a few large (industrial) vessels. The methodology is the "sample-based approach". The data collection methodology presented attempts to utilize whatever information can be obtained in practice in a developing country.
Book Synopsis Improving Fish Stock Assessments by : National Research Council
Download or read book Improving Fish Stock Assessments written by National Research Council and published by National Academies Press. This book was released on 1998-02-27 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean harvests have plateaued worldwide and many important commercial stocks have been depleted. This has caused great concern among scientists, fishery managers, the fishing community, and the public. This book evaluates the major models used for estimating the size and structure of marine fish populations (stock assessments) and changes in populations over time. It demonstrates how problems that may occur in fisheries dataâ€"for example underreporting or changes in the likelihood that fish can be caught with a given type of gearâ€"can seriously degrade the quality of stock assessments. The volume makes recommendations for means to improve stock assessments and their use in fishery management.

Prytherch and published by . This book was released on 1980 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a result of the Fishery Conservation and Management Act of 1976 and the planning and imposition of Fishery Management Plans in the U.S., the number of requests and demands for historical, current, and new kinds of fishery data has increased dramatically. These demands are often well beyond the ability of present staff to respond, well beyond the limitations of available and anticipated economic resources, and well beyond the limitations of data collection systems presently in use. In such a climate, there is an understandable and reasonable desire to maximize the informational return. However, as noted by Wenk (1972), "the federal role at sea has not been continuous or well planned but has grown in a random succession of separate legislative assignments." For example, the National Marine Fisheries is authorized to collect biological, economic, social, and other data many different statutes (see page. 2). The resulting potential for duplicative effort and inefficiency has been great. In order to fulfill their obligations under such a diversity of authorizations, data collection and management systems often subscribe unnecessarily to a variety of recording, storage, and reporting formats. More importantly, computer technology now makes much of the human time and effort involved in current collection and analysis methodology unnecessary. This report is part of an effort to describe and evaluate the present data collection systems now operating within the SEFC of the NMFS in order 1) to facilitate the flow of information in a more timely and continuous manner, 2) to identify and eliminate unnecessary duplication, 3) to determine those components of the collection and analysis process which may more easily and accurately be accomplished by computers and 4) to recommend for implementation those procedures which seem likely to contribute to a better data collection system.

This book was released on 2018-07-10 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2018 edition of The State of World Fisheries and Aquaculture emphasizes the sector’s role in achieving the 2030 Agenda for Sustainable Development and the Sustainable Development Goals, and measurement of progress towards these goals. It notes the particular contributions of inland and small-scale fisheries, and highlights the importance of rights-based governance for equitable and inclusive development. As in past editions, the publication begins with a global analysis of trends in fisheries and aquaculture production, stocks, processing and use, trade and consumption, based on the latest official statistics, along with a review of the status of the world’s fishing fleets and human engagement and governance in the sector. Topics explored in Parts 2 to 4 include aquatic biodiversity; the ecosystem approach to fisheries and to aquaculture; climate change impacts and responses; the sector’s contribution to food security and human nutrition; and issues related to international trade, consumer protection and sustainable value chains. Global developments in combating illegal, unreported and unregulated fishing, selected ocean pollution concerns and FAO’s efforts to improve capture fishery data are also discussed. The issue concludes with the outlook for the sector, including projections to 2030. As always, The State of World Fisheries and Aquaculture aims to provide objective, reliable and up-to- date information to a wide audience, including policy-makers, managers, scientists, stakeholders and indeed all those interested in the fisheries and aquaculture sector.

Book Synopsis Sustainable Fishery Systems by : Anthony Charles
Download or read book Sustainable Fishery Systems written by Anthony Charles and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive attempt to adopt an 'integrated' interdisciplinary approach to the study of fisheries. Fisheries are discussed as holistic 'systems', with emphasis on their structure, operation and dynamics. The book's interdisciplinary approach is applied to an analysis of problems faced in pursuing 'sustainable fisheries', with emphasis on six dominant themes: sustainability, uncertainty, complexity, conflict, fishing rights and the nature of management. Within this discussion, several major directions in current fishery thinking are explored, notably the precautionary approach, the ecosystem approach, co-management, and robust management for resilient fisheries.
