Abstract The aim of this study was to compare the susceptibility body deformities in juveniles 13 common European cypriniform fish, caused by intensive feeding with same commercial dry diet administered at 25°C according a similar schedule. final share individuals malformations differed considerably among species and 0.0-87.0%. Unaffected were only Barbus barbus (L.), Chondrostoma nasus Cyprinu...

Pathogenic Vibrio cholerae non-O1/non-O139 was isolated from the fry of the Cardinal tetra, Paracheirodon axelrodi and in adult Raphael catfish, Platydoras costatus kept in aquarium conditions. Further, an outbreak of vibriosis occurred in the wild populations of common nase, Chondrostoma nasus; chub, Squalius cephalus; gudgeon, Gobio gobio; stone loach, Barbatula barbatula; barbel, Barbus barb...

Benthic grazing strongly controls periphyton biomass. The question therefore arises whether benthic grazing could be used as a tool to reduce excessive growth of periphyton in nutrient-enriched rivers. Although benthic invertebrate grazers reduce the growth of periphyton, this is highly context dependent. Here we assessed whether the only obligate herbivorous fish in European rivers, the common...

Hydropower use of rivers can exert multiple effects on aquatic species and habitats. Due to limitations conservation projects in the main channels hydropower-affected rivers, there has been an increasing focus tributaries, side channels, fish passes as target areas for restoration. However, some these require frequent dewatering their maintenance, ecological such measures remain largely unknown...
