Plasticity in the reproductive biology of Yellowstone cutthroat trout Oncorhynchus virginalis bouvieri in Yellowstone Lake following lake trout Salvelinus namaycush invasion

Journal of Fish Biology, EarlyView.
Abstract Yellowstone cutthroat trout Oncorhynchus virginalis bouvieri in Yellowstone Lake are the focus of intensive conservation efforts due to the threat of predation by invasive lake trout Salvelinus namaycush. Suppression gillnetting has reduced the abundance of predatory lake trout, and the Yellowstone cutthroat trout population is recovering ...

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

Journal 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
