Mark Everard 
Know Your Freshwater Fishes 

The fresh waters of the British Isles are diverse, ranging from torrential hill streams to powerful rivers and wide, meandering lowland channels. Canals and drainage channels, ranging in size from ditches to the large Fenland drains of eastern England also hold fish, as do reservoirs, lakes, ponds and other still water bodies. The fish themselves are correspondingly varied. This pocket-sized book provides information about the 54 native, invasive and naturalised species found in the UK today, and includes a photograph of each to allow easy identification
