This book was released on 1991 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The techniques for using otoliths for annual age determinations in fish are well established (Williams and Bedford 1974). The roughly seasonally alternating pattern of opaque material deposition during fast growth and hyaline material deposition during slow growth, allows researchers to assign an annual age to the fish. pannella (1971, 1974) discovered finer increments in the otoliths and suggested they represented the daily growth. Brothers et ale (1976) later confirmed the daily periodicity of the increments and using SEM showed that these increments were the smallest cyclical units found in the otolith of Engraulismordax. These increments are composed of incremental and discontinuous units. The discontinuous unit is relatively less calcified and is mostly composed of the protein otolin while the incremental unit is mostly composed of aragonite (Campana and Neilson 1985)"--Introduction, paragraph 1.

Corvino and published by . This book was released on 1994 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Southeast Fisheries Science Center (SEFSC) is one of five regional fishery research centers of the National Marine Fisheries Service (NMFS). In 1970, the NMFS was organized as a component of the National Oceanic and Atmospheric Administration (NOAA) in the U.S. Department of Commerce. The Fisheries Science Centers provide scientific information required for decisions relating to the conservation and management of fishery resources, and the protection of fishery habitats, endangered and threatened species. In 1972, the NOAA Technical Memorandum series was established and the Southeast Fisheries Science Center began the publication of research reports. The purpose of this series is timely dissemination of the results of scientific research. The series also affords the SEFSC a means of publishing research results in greater depth and detail than is normally allowed by scientific journals, which usually have stringent length restrictions. To address the difficulties of identification and location of these publications, we present the following listing of SEFSC Technical Memoranda from number 1 (1972) to number 340 (1993). They are available from their originating laboratories or from the National Technical Information Service. A directory of these sources is provided on page 2"--Introduction

Download or read book Tropical Fish Otoliths Information for Assessment Management and Ecology written by Bridget S. Green and published by Springer Science & Business Media. This book was released on 2009-08-07 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Techniques and theory for processing otoliths from tropical marine fish have developed only recently due to an historic misconception that these organisms could not be aged. Otoliths are the most commonly used structures from which daily, seasonal or annual records of a fish’s environmental history are inferred, and are also used as indicators of migration patterns, home range, spatial distribution, stock structure and life history events. A large proportion of projects undertaken on tropical marine organisms involve removal and processing of calcified structures such as otoliths, statoliths or vertebrae to retrieve biological, biochemical or genetic information. Current techniques and principles have evolved rapidly and are under constant modification and these differ among laboratories, and more particularly among species and within life history stages. Tropical fish otoliths: Information for assessment, management and ecology is a comprehensive description of the current status of knowledge about otoliths in the tropics. This book has contributions from leading experts in the field, encompassing a tropical perspective on daily and annual ageing in fish and invertebrates, microchemistry, interpreting otolith microstructure and using it to back-calculate life history events, and includes a treatise on the significance of validating periodicity in otoliths.
Download or read book Fish Energetics written by Peter Tytler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review this literature compre hensively, but, assuming an informed readership, to focus attention on topics in which new knowledge and theory are beginning to be applied in practice. Most emphasis has been placed on food; feeding; production (growth and reproduction) and energy budgeting, as these have most influence on the development of fish culture. Some chapters offer practical advice for the selection of methods, and warn of pitfalls in previous approaches. In others the influence of new theory on the interpretation of studies in fish energetics is discussed in the context of resource allocation and adaptation. We hope that the scope of material presented here will have sufficient interest and value to help significantly to fulfil Winberg's original objectives.
