Fish Population Dynamics, Volume 1J. A. Gulland This book describes how the dynamics of fish populations can be analysed in terms of the factors affecting their rates of growth, mortality and reproduction, with particular emphasis on the effects of fishing. Chapters on individual species or families of fish describe how the methods have been applied to some of the major fisheries of the world. The book gives an understanding of some of the changes that have taken place in the fisheries and provides guidance on the proper conservation an management of these important resources. This book is the first attempt to bring together in a single volume both theoretical methods and practical experience in a wide range of fisheries. |
