This book is the definitive account of all the fish in the salmon and trout family which are renowned for their sporting qualities and succulence. The author aims to appeal to both the angler and naturalist as he contends that angling as a recreation should not be concerned just with the hunting of fish but should be approached also with an interest in the natural environment. In his view, sport fishermen play an important part in the conservation of fish with the current unprecedented threats to fresh water habitats. Their entire life-cycle and world-wide status is described.
