Concentrations of Cu, Zn, Fe, Mn, Pb, Cd, As, and Hg were analyzed in the surface water muscle seven fish species (Carassius auratus, Cyprinus carpio, Hemiculter leucisculus, Pelteobagrus fulvidraco, Silurus meriaionalis, Ctenopharyngodon idellus, Parabramis pekinensis) from Wujiangdu reservoir, China. All metal concen-trations lower than grade one quality values. Mean concentrations decreased ...

Hypoxic events have always naturally occurred in freshwater ecosystems but are worsening due to anthropogenic activities. Hypoxia tolerance greatly varies among fish species and is difficult quantify nature large species. We analysed the movements of 40 subadult adult European catfish Silurus glanis [(727; 2150) mm] exposed a natural summer hypoxic event shallow lake southeastern France. Catfis...

The ecological features of invasive alien species are crucial for their effective management. However, they often lacking in newly invaded ecosystems. This is the case European catfish Silurus glanis L. Lake Maggiore, where present since 1990, but no scientific information available on its ecology. To start filling this knowledge gap, 236 (67 cm to 150 total length) were collected, measured, an...

Fish are among the main target groups when conducting biomonitoring and ecological assessment of aquatic environments. Environmental DNA (eDNA) metabarcoding provides a unique opportunity to enhance throughput, precision, standardization. However, few fish monitoring studies based on eDNA have been conducted at basin scale. Taking Dianchi Lake three inflowing rivers (Panlong River, Baoxiang Cha...
