The results of a series of experimental stocking programmes designed to assess the effects of fin‐clipping, fin‐damage and floy tags on the survival and growth of brown trout ( Salmo trutta L.) are presented. Data indicate that even a single fin clip can seriously reduce survival and also retard the growth of fish. Trout released with extensive fin‐damage also exhibited poorer survival and growth patterns than their unmarked counterparts. The growth and survival of trout (≥ 18 cm) does not appear to have been altered by floy‐tagging.
