FRESHWATER FISHES OF THE BRITISH ISLES (NN 75)

Today fish are no longer seen as simply prey to man's obsession with catching things, but have become important indicators to the health of any water body, as well as a fascinating area of our fauna. In this treatise on freshwater fish, the authors analyze the reasons for the paucity of British fish species as well as identifying reasons for a particular species' distribution. They discuss the biology and its effect on the ecology of each species, including methods of investigation, distribution, habitats, conservation, rare and endangered species and identification.
