Heat exchange rates between adult sockeye salmon (Oncorhynchus nerka) and the environment

Journal of Fish Biology, EarlyView.
Abstract Body temperatures of salmon do not always match the temperatures of their immediate environment. We investigated the relationship between varying ambient water temperatures and body temperatures of adult sockeye salmon Oncorhynchus nerka using Newton's law of cooling and non‐linear mixed models.

Genetic composition of facultatively anadromous brown trout Salmo trutta L. in a freshwater‐lake system

Journal of Fish Biology, EarlyView.
Abstract Brown trout (Salmo trutta) has adapted to a wide range of habitats and displays a variety of life‐history strategies. Being facultatively anadromous, populations without migration barriers to the sea consist of both resident and anadromous individuals in different proportions.

Take my breath away: Defining the oxygen saturation threshold for fish cortisol stress response

Journal of Fish Biology, EarlyView.
Abstract Human activities are affecting the number, size and severity of hypoxic zones in aquatic ecosystems. As oxygen is one of the most important abiotic factors affecting fish biology, exposure to low levels of dissolved oxygen may lead to a reduction in fitness.

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 ...

Modelling relationships between juvenile brown trout (Salmo trutta L.) density and landscape characteristics: Integration of electrofishing data and spatial data to assess population status

Journal of Fish Biology, EarlyView.
Abstract Brown trout (Salmo trutta L.) are ecologically and economically important, but like many salmonids their populations are declining. Trout exhibit a high level of phenotypic plasticity, ranging from freshwater residency to anadromy. This complexity causes problems for assessment and constrains application of adult catch‐based assessment methods
