Presentation Of Recent Data On Fish Catches (Year-Wise In Most Cases) Has Enhanced The Quality Of Book.Matters, On Several Specific Topics Like Hilsa Culture, Trout Culture, Live-Fish Culture, Cage Culture, Paddy-Cum-Fish Culture, Integrated Fish Culture, Brackish Water Fish Culture, Prawn Culture, Shrimp Culture, Molluscan Fisheries, Recent Aquaculture Practices And Useful Seaweeds And Algal Products, Have Been Beautifully Described In The Book. Trade And Commerce Prospects With The Inclusion Of Accounts Of Fish Processing, Fish Preservation, Various Kinds Of Fish By-Products And Scope Of Marketing Of Fish Have Been Made Highly Explicit.A Fine Attempt Has Been Made To Provide As Many As Fifty One Aspects Of Applied Fishery Science, Merging Together In One Book In Order To Meet The Requirements Of Sylabi Of Universities, Technical/Professional Institutions, Advanced Centres Of Fisheries Education And Research. It Is Hoped That The Academicians, Researchers/Fishery Scientists, Graduate And Post-Graduate Students Of Fishery Science Will Cherish The Author S Endeavour In Finding Appreciable Utility Of The Book.
In this 1994 book, Tim Smith examines the economic and political pressures which have affected fisheries science, and the problems that still face it. This is a fascinating resource for all those interested in the way fisheries science has developed in the last 150 years.
It is now clear that data based on the studies of fish eggs and larvae make a number of unique contributions to fishery science that are crucial for accurate assessment and management of fish populations, including those of commercially important fisheries. This valuable book demonstrates why fish eggs and larvae are important, how the characteristics of early life stages require a somewhat different research approach and how information on early life stages can be applied and interpreted to yield unique insights into fish populations. The editors of Fishery Science have drawn together an extremely useful and well-written book with contributions from internationally respected researchers from North America, Asia and Europe. Chapters include a discussion of the unique nature of early life stages, age and growth, mortality, recruitment, populations analysis, habitats, human impacts and management. A carefully selected set of case studies demonstrates several specific applications of early life history information to a number of fishery problems. Fishery Science was designed to complement existing textbooks and is an essential purchase for all fisheries students and professionals, and for biologists working on the early life stages of fish. This exciting book is also of great value to ecologists, marine, freshwater and environmental scientists, populations biologists and oceanographers. All libraries in universities and research establishments where biological and fishery science are studied and taught should have copies of this book available on their shelves.
Marine and fisheries scientists are increasingly using advanced tools to better understand and model their systems to bridge the gap in knowledge of fish behavior and distribution. This book describes the advances in fishery sciences technology which are leading to assessing fish reproductive potential and dispersal in land and marine fishes for economic and ecological advancement.
Introduction to the Fishery Sciences provides a broad introduction into the study of aquatic organisms and ecology of fisheries and some of the legal, social, and political aspects of their use. The book is intended to be used by students and those who want to broaden their knowledge on the science of fishery. The text provides discussions on a wide range of topics such as trends in foodfish production; managing of fishery aquatic environment; identification and classification of fishery resources; and fishery resource management. Limnologists, freshwater biologists, ecologists, fisheries managers, and students in fisheries science will find the book a good reference material.
Stock Identification Methods, 2e, continues to provide a comprehensive review of the various disciplines used to study the population structure of fishery resources. It represents the worldwide experience and perspectives of experts on each method, assembled through a working group of the International Council for the Exploration of the Sea. The book is organized to foster interdisciplinary analyses and conclusions about stock structure, a crucial topic for fishery science and management. Technological advances have promoted the development of stock identification methods in many directions, resulting in a confusing variety of approaches. Based on central tenets of population biology and management needs, this valuable resource offers a unified framework for understanding stock structure by promoting an understanding of the relative merits and sensitivities of each approach. Describes 18 distinct approaches to stock identification grouped into sections on life history traits, environmental signals, genetic analyses, and applied marks Features experts' reviews of benchmark case studies, general protocols, and the strengths and weaknesses of each identification method Reviews statistical techniques for exploring stock patterns, testing for differences among putative stocks, stock discrimination, and stock composition analysis Focuses on the challenges of interpreting data and managing mixed-stock fisheries
Drawing on a number of case studies from around the world, this publication considers how the local knowledge and practices of indigenous fishing communities are being used in collaboration with scientists, government managers and non-governmental organisations to establish effective frameworks for sustainable fisheries science and management. It seeks to contribute towards achieving the goal of establishing international responsibility for the ethical collection, preservation, dissemination and application of fishers' knowledge.
Introduction to the Practice of Fishery Science covers the role of fishery science in various social affairs. This book is divided into three parts encompassing 15 chapters. Part I is about the profession, what is embodied in a professional career and the expanding challenges to the profession, with a summary of the work of organizations that employ fishery scientists. Part II deals with the traditional sciences that apply to the aquatic environment and its organisms. This part also tackles their biology, ecology, populations, and culture. Part III presents an overall qualitative concept of the activity of fishery scientists. This part also provides a perspective on fishery problems in several major areas and the ways in which the many kinds of scientists are attacking them. This book will prove useful to fishery scientists, researchers, and students.
Summarizes a growing body of information on applications of geographic information systems (GIS) in fisheries research and management.
The main objective of this manual is to present the basic and standard concepts of sampling methods applied to fisheries science. In order to ensure sound fisheries research, it is essential to have reliable data from landing ports, fishery stocks and research surveys. A rational management of fishing resources can then be established to ensure a sustainable exploitation rate and responsible fisheries management, providing long-term benefits for all. This document provides an introduction to sampling theory and introduces the theory of the three worlds (population, sample and sampling), as well as a short revision of probability concepts. It also provides an overview of the simple random, random stratified, cluster and two-stage sampling methods. The expressions for estimating the mean and total of the populations, their sampling distributions, the expected values, the sampling variances and their estimates are included and justified for each of the sampling designs. The document also contains a case study of biological sampling from landing ports and exercises that should be used to further understanding of the objectives of sampling and its advantages for fishery resource studies.
