Trophic ecology of the pikeperch (Sander lucioperca) in its introduced areas: a stable isotope approach in southwestern France.
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...
متن کاملAnalysis of diet of piscivorous fishes in Bovan, Gruža and Šumarice reservoir, Serbia
Diet of adult pikeperch Sander lucioperca, Eurasian perch Perca fluviatilis, northern pike Esox lucius and European catfish Silurus glanis as top predators in aquatic ecosystems in Serbia was investigated during 2011, in order to understand their relationship to their prey and to investigate their food consumption, feeding and assimilation rate, cannibalism, and habitat segregation. Northern pi...

متن کاملArsenic and Other Trace Elements in Five Edible Fish Species in Relation to Fish Size and Weight and Potential Health Risks for Human Consumption
The main objectives of study were to determine the concentrations of As and other trace elements (Al, Co, Fe, Ni, Sn, Se) in the muscle, liver, and gills of pikeperch (Sander lucioperca), catfish (Silurus glanis), and pike (Esox lucius), and in the muscle of Prussian carp (Carassius gibelio) and freshwater bream (Abramis brama), to identify relationships between element concentrations and total...
متن کاملIs European catfish Silurus glanis really becoming more abundant in the River Thames?
An increased number of reports (by anglers, in the angling press) of European (wels) catfish Silurus glanis occurrences in the River Thames (England) has led to the perception that the species has become more abundant in that river. If proved true, then this would have ramifications for non-native species policy and practice. To assess catfish density, a total of 256 rod hours of specialized an...
