Pelagic distribution and night foraging of early juvenile <scp>European</scp> catfish ( <i>Silurus glanis</i> <scp>L</scp> .)
This study provides evidence of pelagic occurrence and night feeding in early juvenile European catfish that contributed 0.2% to the early juvenile pelagic community at night in Klíčava, 0.3% in Římov, and 3.3% in Žlutice Reservoirs in the Czech Republic. The catfish occurred mostly at a depth of 2-4 m. Their abundance was 5.5 inds.1000 m<sup>-3</sup> in Klíčava Reservoir (2018), 0.3 inds.1000 m<sup>-3</sup> in Římov Reservoir (2018), and 88.8 inds.1000 m<sup>-3</sup> in Žlutice Reservoir (2019). Catfish fed on phantom midges (Chaoborus sp.).
