Points vs. passes: A comparison between electric fishing techniques for sampling fish populations in upland headwater streams

Journal of Fish Biology, EarlyView.
Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.

Contrasting population genetic structures of congeneric coastal flounders associated with different early life histories

Journal of Fish Biology, EarlyView.
Abstract Marine fish species are likely to exhibit little genetic differentiation among populations due to their high dispersal potential during early life stages and migratory nature. However, recent studies have increasingly reported intraspecific genetic differentiation resulting from species‐specific ecological traits, environmental factors, and ...

Conservation genomics of Pecos pupfish (Cyprinodon pecosensis)

Journal of Fish Biology, EarlyView.
Abstract The Pecos pupfish, Cyprinodon pecosensis, is an imperilled freshwater fish found in arid regions of Texas and New Mexico (USA). The species faces multiple challenges to persistence including reductions in suitable habitat, water shortages, as well as hybridization and competition with an introduced congener (sheepshead minnow, C.

Marine heatwaves shape size‐dependent thermal exposure, habitat use and marine residency in Arctic char (Salvelinus alpinus)

Journal of Fish Biology, EarlyView.
Abstract Marine heatwaves (MHWs) are increasing in high‐latitude oceans, yet behavioural responses of anadromous fishes to these potential stressors during short marine feeding seasons remain poorly understood. We combined acoustic telemetry (internal temperature and depth) with satellite‐derived sea surface temperature data to quantify Arctic char ...

Impacts of predator odours and conspecific disturbance cues on minnow thermal tolerance

Journal of Fish Biology, EarlyView.
Abstract Warming waters can affect fish community dynamics, potentially exacerbating predator–prey asymmetries in behavioural and physiological metrics of thermal tolerance. Further, differing responses of prey fish species to concurrent predation risk and warming highlight the need to understand these impacts in various contexts, especially with at ...
