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.
