Reproductive parameters of wild and hatchery‐reared sea trout (Salmo trutta m. trutta L.) females from the Łeba River (southern Baltic Sea)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Sea trout Salmo trutta m. trutta L. has high socioeconomic and ecological importance in the Atlantic region; therefore, stocking hatchery‐reared fish is widely practiced for stock enhancement and recovery of wild populations. In this study, fecundity of wild and stocked hatchery‐reared sea trout sampled from the Łeba River (southern Baltic Sea
