Description

Diadromy is a phenomenon involving migration of fishes between freshwater and the sea, and is widely represented amongst diverse groups, particularly the salmons and trouts, but also the sturgeons, lampreys and others. It is of considerable interest to fish biologists as the fish must show physiological adaptability to cope with the different environments. It is also of wide relevance to fisheries scientists, particularly those concerned with salmon and trout. This book is probably the first specifically to review this topic. It describes the fish which exhibit diadromy, their life history strategies and the implications for fisheries.
