about

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.

Table of Contents

Series foreword; A.J. Pitcher. Foreword; D. Pauly. Part One: Fundamentals of the theory of fishing, illustrated by analysis of a trawl factoy. Introduction:- theoretical methods in the study of fishery dynamics. The basis of a theoretical model of an exploited fish population and definition of the primary factors. Mathematical representation of the four primary factors. Recruitment. Natural mortality. Fishing mortality. Growth. A simple model giving the annual yield in weight from a fishery in a steady state. Adaptation of the simple model to give other characteristics of the catch and population. Part Two: Some extensions of the simple theory of fishing. Recruitment and egg-production. Natural mortality. Fishing mortality and effort. Growth and feeding. Spatial variation in the values of parameters; movement of fish within the exploited area. Mixed populations:- the analysis of community dynamics. Part Three: Estimation of parameters. Relative fishing power of vessels and standardisation of commercial statistics of fishing effort. Estimation of the total mortality coefficient (F + M), and the maximum age, t*. Seperate estimation of fishing and natural mortality coefficients. Recruitment and egg-production. Growth and feeding. Part Four: The use of theoretical models in a study of the dynamics and reaction to exploitation of fish populations. Application of population models of part one. Application of population models of part two. Principles and methods of fishery regulation. Requirements for the regulation of the North Sea Demersal fisheries. Appendices.
