The main objective of this study was to collect new data on the occurrence, levels of priority and emerging organic compounds in freshwater fish sampled in the Rhone River. The 34 studied contaminants included alkylphenols, bisphenol A, polybromodiphenylethers (PBDE), perfluorinated compounds, hexabromocyclododecanes (HBCD), hexachlorobenzene and hexachlorobutadiene (HCBD). About 50 fish sample...
The distribution and reproductive success of fish were examined in Dutch soft waters of varying pH. In total, 20 fish species were encoun tered. The lowest pH-values at which fish species were observed varied remarkably. Umbra pygmaea and Tinea tinea appeared to be extremely acid tolerant and occurred in waters with pH-values below 4.0. Abramis brarna, Cyprinus carpio, E’sox iucius, Misgumus f...
Fish-habitat associations are poorly known in offshore areas of very large rivers. We examined physical habitat structure and its effect on use assemblage formation benthic fishes the main channel Danube River, Hungary. Principal component analysis variables showed that sample unit (i.e., 500 m long reaches) cross-channel transect-level data corresponding reaches were highly correlated. found c...
