This illustrated guide describes the many ways that coarse fish species depend upon the diversity of habitats in river systems and considers how this dependence changes throughout the stages of their lives – from spawning and eggs, through to the juvenile and adult stages- and with changing seasons and river conditions. This knowledge is important if we are to understand the many population bottlenecks and the variety of coarse fish species that have resulted from historic changes to our rivers. It is also important if we are to manage rivers positively to protect and improve the vitality of coarse fisheries – a process that will also benefit the wider wildlife community with which coarse fish are interdependent.
