Fish are particularly sensitive to connectivity loss as their ability to reach spawning grounds is seriously affected. The most common way to circumvent a barrier to longitudinal connectivity, and to mitigate its impacts, is to implement a fish passage device. However, these structures are often non-effective for species with different morphological and ecological characteristics so there is a ...

Previous research indicated that high predictive performance in species distribution modelling can be obtained by combining both biotic and abiotic habitat variables. However, models developed for fish often only address physical habitat characteristics, thus omitting potentially important biotic factors. Therefore, we assessed the impact of biotic variables on fish habitat preferences in four ...

We evaluated the individual and combined effects of salinity and alkalinity on gill Na+/K+-ATPase enzyme activity, plasma ion concentration, and osmotic pressure in Luciobarbus capito. Increasing salinity concentrations (5, 8, 11, and 14 g/L) were associated with an initial increase and then decrease in L. capito gill Na+/K+-ATPase activity. Activity was affected by the difference between inter...

Human pressures on water resources have been suggested as a driver of biological traits that induce changes in native fish populations. This study highlighted the interplay between environmental stress factors, mostly related to flow regulation, and longitudinal river gradient such growth, size structure somatic condition sentinel fish, Luciobarbus sclateri. We found an increase size-related me...

Cadmium (Cd) poses a great threat to the breeding of aquatic economic animals. The present study aimed explain antagonistic effects selenium-enriched Lactobacillus plantarum (SL) on Cd toxicity through expression oxidative and inflammatory factors. A total 225 Bulatmai barbel Luciobarbus capito (L. capito) were divided into 3 groups, namely, control group, group (Cd, 0.05 mg·L−1), SL + mg·L−1; ...
