The accumulation of some heavy metals such as Pb, Cd, Cu and Ni was determined in water sediment and fish samples (Albumus escherichii, Cyprinus carpio and Silurus glanis) collected from Nallihan Bird Paradise (NBP) and its vicinity (Sariyar Dam). The results showed that these metals are found widespread throughout the study area, but metal concentrations in the water samples are below the dete...

During the last decades, non-native predatory fish species have been largely introduced in European lakes and rivers, calling for detailed information on the trophic ecology of co-existing native and non-native predators. The present study describes the trophic ecology of the introduced pikeperch (Sander lucioperca) in two southwestern French rivers, using stable isotope analysis. Pikeperch cou...

Abstract The aim of this research is to compare the average individual weight four most important fish species in fisheries ( Cyprinus carpio, Silurus glanis, Esox lucius and Sander lucioperca ), caught by angling different parts Sava River catchment Croatia. Significant differences were expressed between counties along catchment, with smallest specimens (p˂0.05) Vukovar-Sirmium county. Artisan...

An acute infectious disease of northern sheatfish (Silurus soldatovi) was found in a commercial aquaculture pond Tianjin, China. Herein, two dominant bacterial strains were isolated from naturally diseased and identified as Aeromonas veronii Vibrio cholerae. Seven healthy seven fish that collected the used for gut microbiota analysis by high-throughput 16S rRNA gene sequencing. The α-diversity ...
