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

Ontogeny of escape response and body shape in threespine stickleback (Gasterosteus aculeatus L.)

open access: yesJournal 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 ...

Deciphering the complex life cycle and partial migration of an ecological engineer and critical Neotropical fishery species, Prochilodus costatus

open access: yesJournal of Fish Biology, EarlyView.
Abstract Understanding complex migration patterns, including drivers of partial migration and habitat use, is challenging but essential for conservation, as it determines a species' adaptative capacity in the face of environmental change and anthropogenic threats.

Return migration to fresh water and overwintering locations used by sympatric anadromous populations of Arctic char (Salvelinus alpinus) and Dolly Varden (Salvelinus malma malma)

open access: yesJournal 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 ...

Surgical tagging of Atlantic mackerel (Scomber scombrus): electroanaesthesia and survival in captivity and the field

open access: yesJournal of Fish Biology, EarlyView.
Abstract Electroanaesthesia using electric fish handling gloves induced rapid and reversible sedation of Atlantic mackerel (Scomber scombrus) during surgical tagging without observable adverse effects on behaviour or tag retention. In the laboratory, survival analyses revealed that longer handling times and smaller body sizes significantly reduced ...

Genetics of Central Valley, O. mykiss, Populations: Drainage and Watershed-scale Analyses

open access: yesSan Francisco Estuary and Watershed Science, 2005
Genetic variation at 11 microsatellite loci described population genetic structure for Oncorhynchus mykiss in the Central Valley, California. Spatial and temporal variation was examined as well as relationships between hatchery and putative natural ...

Etiology of Ulcerative Dermal Necrosis (UDN) in Brown Trout (Salmo trutta Morpha trutta)—Preliminary Results

open access: yesPathogens
Every year, ulcerative dermal necrosis (UDN) affects salmonids that spend most of their lives in the sea during their migration to the rivers of northern Poland to spawn. The clinical form of the disease manifests itself in ulcerative skin lesions, which

The lake sink in Atlantic salmon smolt downstream migration

open access: yesJournal of Fish Biology, EarlyView.
Abstract The objective was to estimate the movements and survival of Atlantic salmon smolts migrating downstream through a river–lake system consisting of two large, interconnected lakes (areas 58.2 and 13.2 km2, minimum crossing distance 29 and 16 km).
