Freshwater fish - Malcolm Greenhalgh

European lakes, rivers, reservoirs and canals are home to a huge number of fish species. In this book, Malcolm Greenhalgh explores over 160 species, from primitive lamprey to the Atlantic salmon and from the massive sturgeon to the tiny guppy. Understanding fish is the key to finding them, and the author therefore explains the appearance, range, habitat, courtship, breeding, life-cycle and feeding behaviour of each species. The book is organized by fish family and closely related species are grouped together, so that minor differences in appearance or behaviour can be easily recognized. The author also explores the conservation issues that threaten fish throughout Europe, including the effects of introducing fish to areas where they would not occur naturally, as well as pollution and over-fishing.
