This book was released on 2021-07-06 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine recreational fisheries are an integral part of Mediterranean and Black Sea coastal life and are commonly practiced throughout the region. Recreational fisheries also represent an important driver of coastal tourism, which constitutes one of the region’s most important maritime sectors in terms of gross value added and employment. However, despite their ubiquity and potential socio-economic contribution, recreational fisheries are a data-poor sector and can vary widely from one country to another, thus impairing proper consideration of the recreational fisheries sector in policy-making and undermining efforts towards sustainable fisheries management at the regional level. The main goal of this handbook is therefore to provide a clear methodological framework to allow Mediterranean and Black Sea countries to implement suitably harmonized sampling and survey monitoring schemes for recreational fisheries. This handbook establishes a minimum set of necessary information for monitoring recreational fisheries, while, at the same time, allowing for flexibility to accommodate national specificities and data collection needs. It also provide guidance on the data analysis process as well as advice to successfully engage stakeholders in the data collection process.

Book Synopsis Strait of Georgia Chinook and Coho Fishery by : A. W. Argue
Download or read book Strait of Georgia Chinook and Coho Fishery written by A. W. Argue and published by . This book was released on 1983 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chinook (Oncorhynchus tshawytscha) and coho (O. kisutch) salmon fishery in the Strait of Georgia, between Vancouver Island and the mainland of British Columbia, is a valuble sport and commercial resource. In an effort to evaluate proposed regulations on sport and commercial fishermen (season closures, size limits, bag limits, etc.), a computer simulation model was developed. The model calculates the abundance and size of the natural and enhanced stocks of chinook and coho for each age-class and evaluates regulatory options by simulating the life history of these fish in half-monthly intervals. Cohorts enter the model as smolts and are followed through natural mortality, emigration out of the Strait of Georgia, fishing mortality, shaking mortality, maturation, and spawning. The major effect of any regulation that reduces catch to one user increases the catch to other users of the resource. Any attempt to increase spawning escapement without regulation of several users simultaneously is destined to failure, and even quite harsh regulations do not double the critical chinook escapement. Finally, it is found that "enhancement" of chinook and coho will lead to a more rapid decline of natural stocks unless regulations are found to reduce overall exploitation rates on these stocks.

Book excerpt: Computation and Interpretation of Biological Statistics of Fish Populations, first published in 1975, deals with the general field of biological statistics of fish populations. It is a compilation of the more important procedures used to estimate abundance, age composition, rate of growth, and mortality rates in fish populations, with working examples of all the computations. Computation and Interpretation of Biological Statistics of Fish Populations is one of the most highly cited scientific references in the field of fisheries.
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.
