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 ...

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 Movement patterns and habitat use of yellow‐phase American eels Anguilla rostrata in the Wolastoq/Saint John River were examined using acoustic telemetry. Tracking 72 tagged yellow‐phase eels from late summer 2021 to autumn 2023 revealed overall restricted longitudinal movements (mean linear range ± standard deviation [SD] 6.4 ± 10.9 km) and ...

A Bioeconomic Analysis of a Wild Atlantic Salmon (Salmo salar) Recreational Fishery [PDF]
A biomass model of a wild salmon (Salmo salar) river recreational fishery is formulated, and the ways in which economic and biological conditions influence harvesting, stock size, profitability, and the benefit of the anglers are studied.

Journal of Fish Biology, EarlyView.Abstract Life‐history data are often lacking for exploited elasmobranchs, jeopardizing proper management and conservation measures for this vulnerable group. Herein, we provided age and growth estimates for the groovebelly stingray (Dasyatis hypostigma), a medium‐sized, heavily exploited batoid endemic to the southwestern Atlantic Ocean.

Journal of Fish Biology, EarlyView.Abstract Characidium tupi, a new species from rivers draining the southern portion of the Northeastern Mata Atlantica Freshwater Ecoregion, is described. The new species can be distinguished from all congeners by its colour pattern, including 7–14 dark bars enlarged and more conspicuous on their ventralmost portion, resulting in a longitudinal series ...

Journal 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 ...

Journal of Fish Biology, EarlyView.Abstract Four new species of the small‐sized armoured catfish genus Pareiorhina are described from mountain ranges in the Grande River drainage, upper Paraná River basin, based on morphological and molecular species delimitation methods. Molecular analyses based on the cytochrome oxidase subunit I (COI) marker recovered Pareiorhina as polyphyletic ...
