Effects of stream regulation on atlantic salmon, Salmo salar L., and brown trout, Salmo trutta l., in the upper severn catchment, U.K.

Abstract Data for three rivers in the upper Severn catchment are examined to assess the influence of regulation strategies on the Atlantic salmon and brown trout populations. In the regulated Afon Clywedog, juvenile recruitment of both species declined steadily following increased utilization of the...
