The rocky reefs and coral communities reefs of Hong Kong shelter a rich and beautiful fish fauna largely unknown to those who have never ventured underwater. This book documents the first comprehensive survey of reef fishes ever undertaken in Hong Kong. It includes descriptions and colour photographs of over 320 fish species, a third of which have never before been recorded here. The book will be of value to divers, fishermen, biologists and other professionals who wish, or need, to identify locally occurring fishes and to learn about their biology and distribution in the northern sector of the South China Sea.
