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 Ecology of Teleost Fishes written by Robert J. Wootton and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 415 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 and delicious food of numerous kinds. Rational expoitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman and 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.
Download or read book Predicting Year class Strength from the Abundance of Age 0 Rockfish written by James R. Bence and published by . This book was released on 1990 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Groundfish Analysis Investigation of the Tiburon Laboratory conducts an annual survey of age-0 rockfish (Genus Sebastes). A major long-term goal of these surveys is to estimate the strength of a year class based on their abundance at age 0. This requires that a positive relationship between recruitment to the fishery and age-0 abundance be established. In this report we examine the statistical power for establishing such a relationship."--p.ii
Download or read book Stock Assessment written by Vincent F. Gallucci and published by CRC Press. This book was released on 2023-05-31 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stock Assessment: Quantitative Methods and Applications for Small Scale Fisheries is a book about stock assessment as it is practiced. It focuses on applications for small scale or artisanal fisheries in developing countries, however it is not limited in applicability to tropical waters and should also be considered a resource for students of temperate fishery management problems. It incorporates a careful sample design, various mathematical models as a basis for predicting consequences for stock exploitation, and discusses the impact of exploitation on non-targeted species. This was a unique concept involving a collaborative effort between U.S. and host country scientists to address issues of regional and global concern through innovative research. Unlike other books on stock assessment that show mathematical models, this is the only book of its kind that discusses how an assessment is carried out. It looks at the field as a whole and includes sampling, age determination and acoustics. The book represents the culmination of a nine-year program financed by the United States Agency for International Development to provide new or improved methods of stock assessment for artisanal fisheries.

This book was released on 1992 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of otolith microstructure research has experienced phenomenal growth since the early 1970s and now forms the basis for hundreds of studies in early life history, age, growth, recruitment, migration, mortality and stock structure. This book represents the first effort to compile and summarize the many techniques and procedures associated with studies of otolith microstructure. The complete sequence of events, from sample collection to data analysis, is covered comprehensively, so as to be applicable to most species and situations. The various chapters include both published and unpublished procedures.
Download or read book A Universal Method for Preparing Sectioning and Polishing Fish Otoliths for Daily Ageing written by Sheryan Patricia Epperly and published by . 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.
