"This book is concerned with the ecology of exploited fish populations. It differs from existing texts in its broad view of the subject, including a consideration of fish as elements in a delicately-balanced ecosystem, features of their adaptive physiology and behaviour, and the economics of fisheries in terms of a throughput of both energy and finance. The treatment is worldwide, and includes reference to freshwater fisheries as well as marine". Chapters include: Fish design plans and fish communities; World fisheries; The structure of fish populations in space and time; Fish nutrition, growth and production; Evolutionary effects of mortality; Recruitment; Prediction of fishery yields - surplus yield models; Dynamic pool models and fishery management; Fishery economics; Fish farming; Fisheries and the ecology of man. The appendix explains cohort analysis.
