- catalog abstract "This book relates some fundamental aspects of biological oceanography and freshwater biology to global aspects of the future protein nutrition of man and to our understanding of the processes of evolution. Seasonal and other factors controlling organic productivity in temperate oceans are outlined, and more unusual trophic features are considered. Methods for future exploitation of the oceans--particularly through sea-farming--are discussed and critically assessed. The finite nature of the oceans' resources is stressed. Energetics of food chains, the dynamics of exploited fish stocks, and the biogeochemistry of organic cycles are clearly explained and examined.-- From publisher's description.".
