Despite being among the most widespread and common fish in the UK there is still a lack of knowledge about the small freshwater fish species that inhabit our rivers and waterways. Often neglected but endlessly charming, these small fish are, for many, their first childhood encounter with the underwater world and inspire a lifelong interest and enduring fascination. As threats to biodiversity grow and conservation efforts intensify, it is important to remember that fishes are wildlife and that common yet overlooked species require respect and wider consideration. Providing details of their biology, the wider angling interest and many other social dimensions, this book celebrates Britain's small freshwater fishes and recognises their importance to both the academic and general fish enthusiast. The value of this book includes: * Providing detailed systematic descriptions of some well-known but less well understood UK small fish species. * Written by a popular and knowledgeable broadcaster (BBC Springwatch) and author adept at crafting works that are valued by joint audiences (academics, general fishermen and beginner anglers). * Illustrated with photographs from acclaimed underwater photographer, Jack Perks. * Recognising that small freshwater fish species are important wildlife and that there are great stories to be told about our littlest fishes. This book shines a light on the range of familiar but less studied UK small freshwater fish species for academic use but it is also written for the accessibility of a general readership. It is an engaging, factual and beautifully illustrated account of these wonderful, tiny creatures and brings their stories to life.
