Journal of Fish Biology, EarlyView.Abstract Resource pulses are infrequent, ephemeral events of resource hyperabundance that can represent important feeding opportunities for consumers. To capitalize on pulsed resources, consumers can exhibit behavioural and physiological traits including binge‐feeding and phenotypic plasticity of digestive physiology, although expression of these ...

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

Ontogeny of escape response and body shape in threespine stickleback (Gasterosteus aculeatus L.)
Journal of Fish Biology, EarlyView.Abstract Escape responses in fishes provide insight into accelerative motions and behavioural response times of these animals, linking numerous fitness‐related traits. We sought to connect escape response performance to genotype and phenotype across ontogenetic stages within a single population of threespine stickleback (Gasterosteus aculeatus L.) to ...

Journal of Fish Biology, EarlyView.Abstract Anadromous Arctic char (Salvelinus alpinus) and northern form Dolly Varden (Salvelinus malma malma) are highly valued by Indigenous communities in northern Canada. Rapid, ongoing environmental changes are affecting populations of both of these iteroparous species, and understanding variability in life‐history tactics is essential for ...
