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.

Available in PDF, EPUB and Kindle. Book excerpt: Research on the large array of tropical estuarine fishes has increased markedly in recent years and hence scientific knowledge about most aspects of these important fishes' biology and ecology is now catching up with that of their temperate equivalents. This landmark book draws together a vast wealth of information on tropical estuarine fishes and provides a vital reference point for all aspects of their study. The book's comprehensive contents include thorough coverage of the types and distribution of these fishes, their diversity and the environmental conditions and communities in which they live. Full details of their biology and ecology are an integral part of this book, as are details of these fishes' dependence on estuaries, man's interaction with the estuarine fish community and the conservation of estuarine species and the often threatened habitats upon which they depend. The author, Stephen Blaber, has a vast wealth of experience in the subject areas covered by this book and has produced a stimulating and extremely valuable volume that will be of huge importance for all those concerned with these fishes. He is based at CSIRO Marine Research, Cleveland, Queensland, Australia. Readership should include: fish biologists; fisheries scientists; aquatic scientists including those concerned with brackish, marine and freshwater environments; ecologists; environmental scientists and population biologists. Students studying for qualifications in fish biology and fisheries, particularly where there is a tropical element to their course will find this book of great value as a reference. Copies of the book should be available on the shelves of all libraries in research establishments and universities where biological sciences, fish biology, fisheries science or aquatic sciences are studied and taught.

Available in PDF, EPUB and Kindle. Book excerpt: The fields of fish population dynamics and stock assessment have seen major advances in the 1980s and 1990s, creating the need for a new synthesis. This text attempts that synthesis by presenting a contemporary approach for quantitative fisheries science that incorporates modern statistical and mathematical techniques. It emphasizes the link between biology and theory by explaining the assumptions inherent in the quantitative methods and models. The book covers key topics that are often overlooked in other texts, such as optimal harvesting, migratory stocks, and complex age and size-structured models. Quantitative Fish Dynamics is an ideal textbook for graduate and undergraduate courses in fish population dynamics and stock assessment. It is an indispensable reference work for fisheries scientists and others interested in conservation biology, fish and wildlife management, population ecology, and statistical applications.

This book was released on 1995-01-01 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fishing selectivity can be defined as the ability to target and capture fish by species, size, or sex (or a combination of these) during harvesting operations, allowing all incidental by-catch to be released unharmed. This manual outlines the steps and processes necessary to monitor selectivity demonstrations, collect data on selectivity, and validate scientific research on selectivity under normal fishing operations. Some mathematical and statistical examples are shown to clarify the methodologies and to facilitate understanding and application. The manual is intended to provide assistance to technicians and senior fishing crew in the planning, execution, and reporting of size and species trials and demonstrations with mobile and fixed gears. Sections of the manual cover measurement of selectivity, experiment design, experimental methods, data analysis, and the reporting of results. Case studies of experiments using both fixed and mobile gear are included.

This book was released on 2012-12-06 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the fishes, a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes, ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts, in the deep sea, in the cold antarctic, and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specializations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins, sailfish and warm-blooded tunas, air-breathing in catfish and lungfish, parental care in the mouth-brooding cichlids, and viviparity in many sharks and toothcarps. Moreover, fish are of considerable importance to the survival of the human species in the form of nutritious, delicious and diverse food. Rational exploitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman & Hall Fish and Fisheries Series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology, zoology, ecology and physiology but an additional aim is for the books to be accessible to a wide spectrum of non-specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of fish and fisheries.

Available in PDF, EPUB and Kindle. Book excerpt: The fisheries of China generate the largest catch in the world. However, these fisheries are in generally bad shape, notably due to lack of management systems based on rigorous studies on the dynamics of major stocks exploited by the fisheries of China and neighboring countries. This could be mitigated, at least in part, by the systematic application of newly developed methods for evaluating the status of exploited fish stocks for use in data-sparse situations, focusing on methods for estimating maximum sustainable yield (MSY) from catch informed by a combination of biological knowledge on the species (intrinsic rate of population increase, r, and carrying capacity, k) and what is known about the stock, for instance relative abundance indicators, e.g., catch per unit of effort. The aim of this Research Topic is to create an outlet for the studies that will result from the application of these modern methods to exploited stocks of East Asian marine fish, encouraging the rigorous evaluation of these stocks and providing a basis for their rebuilding, as required especially for Chinese stocks. This would lead to the creation of a cadre of fishery scientists knowledgeable in using the methods in question and interested in collaborating with colleagues in other regions with similar issues. Focusing on East Asia will reinforce to readers in `the West' that these fisheries are not a sideshow to the more interesting fisheries in Europe or North America, but a major source of seafood for people in East Asia. Indeed, the failure of these domestic fisheries would increase the impacts of distant-water fisheries from East Asia in other parts of the world.
