    schema:description "There is a general impression that changes in fish stocks are mainly caused by intensive fishing. Scarcely publicized are the multitude of causes of fish stock fluctuations. This book attempts to summarize the available knowledge on the subject and includes original work of the authors on a matter vital to the fisheries industries of the world. The influence of catches on the age composition of exploitable stocks is explained with quantitative examples, and it is shown that the influence of heavy fishing on stocks is, in many cases, smaller than previous theories suggest. The effects of fishing are compared to those of natural factors influencing stock fluctuations. This quantitative knowledge of the effects of fishing will help to promote better fisheries management and emphasize its importance. This book summarizes and evaluates conventional methods of fishery resource assessment and factors affecting recruitment fluctuations, as well as the effect of ocean environmental factors and behaviour of fish to fishing gear."@en ;
