The ichthyofauna of the upper Neretva River

open access: yesNatura Sloveniae, 2023
Fish were sampled at nine locations of the upper Neretva River, upstream of Glavatičevo. Evidence of the endangered softmouth trout (Salmo obtusirostris) was obtained as well as the presence of other native and non-native salmonids.

Effects of introduced trout predation on non-diadromous galaxiid fish populations across invaded riverscapes [PDF]

open access: yes, 2013
We assessed the landscape-scale effect of predation pressure from trout on the population integrity and distributions of non-diadromous galaxiids in high-country streams of the South Island, New Zealand.

Impact of Environmental Conditions on the Spawning Migration of Sea Trout (Salmo trutta L.) in Two Large, Sub‐Arctic River Systems

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT The global decline in salmonid stocks has increased the need for knowledge of local adaptations and life history strategies of salmonids. In this study, we used radio‐telemetry tracking data from sea trout populations in two large high‐latitude rivers to model upstream spawning migration speed of trout in response to prevailing environmental ...

Use and Trust of Digital and Traditional Media Among Recreational Anglers in Germany: Findings From a Nationwide Survey

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Data on recreational fisheries are often limited, and scientists increasingly use digital platforms to collect information otherwise difficult to obtain. Using telephone‐diary survey data, this study examines angling‐related media use (face‐to‐face communication, angling magazines, TV or radio, YouTube, messenger services, social media, other ...

Predicting presence and absence of trout (Salmo trutta) in Iran

open access: yesLimnologica, 2014
Species distribution modelling, as a central issue in freshwater ecology, is an important tool for conservation and management of aquatic ecosystems. The brown trout (Salmo trutta) is a sensitive species which reacts to habitat changes induced by human impacts. Therefore, the identification of suitable habitats is essential.

Variability in Fecundity–Body Size Relationships for Atlantic Salmon Associated With Body Condition and Life History

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT While body size is the primary driver of fecundity, other factors may contribute to variation in these relationships. Anadromous populations of Atlantic salmon (Salmo salar) have diverse life histories, and fisheries management relies on accurate fecundity estimates.
