Název v původním jazyce

Recapture rate and growth of hatchery-reared brown trout (Salmo trutta v. fario, L.) in Blanice River and the effect of stocking on wild brown trout and grayling (Thymallus thymallus, L.)

Popis výsledku v původním jazyce

Hatchery-reared adult brown trout, Salmo trutta v. fario L., [215-335 mm standard length (LS), n = 82] were individually tagged and released into three sections of the Blanice River in May 2007. Wild populations of brown trout and grayling, Thymallus thymallus, L., in these sections and in three unstocked control sections were also tagged. The recapture rate of hatchery-reared adult brown trout after six months (18%, n = 15) was comparable to that of wild adult brown trout in stocked (15%, n = 14) and control (14%, n = 11) sections. The recapture rates of wild brown trout and grayling after six months were higher in control sections than in stocked sections, but differences were not significant. The movement of recaptured large juvenile wild brown trout from stocked sections was significantly higher (36%) than from control sections (9%). The growth of wild brown trout and grayling was unaffected by stocking with adult hatchery-reared brown trout.
