The early life history of fish is of vital interest to biologists working with fish and fisheries. A full understanding of the developmental stages and processes involved is necessary to help avoid potential commercial losses in aquaculture systems, for example. This book brings together current knowledge of the growth of fish gonads, the endogenous feeding period and larval life, much of this work appearing here in the English language for the first time. Special attention is given to the effects of internal and external factors on growth rate and subsequent offspring quality with its effcts on aquaculture systems. As well as reviewing present information, the author also points out the relevance of our current knowledge to problems which will require further study in the future. "Early Life History of Fish" is aimed at all those with an interest in and working in the areas of fish biology, fisheries, aquaculture, physiology and developmental biology.

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 ofconsiderable importance to the survival ofthe human species in the form of nutritious and delicious food of numerous kinds. Rational exploitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman and 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 ofnon specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of fish and fisheries.
