摘要：
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 Kl & iacute;& ccaron;ava, 0.3% in & Rcaron;& iacute;mov, and 3.3% in & Zcaron;lutice Reservoirs in the Czech Republic. The catfish occurred mostly at a depth of 2-4 m. Their abundance was 5.5 inds.1000 m-3 in Kl & iacute;& ccaron;ava Reservoir (2018), 0.3 inds.1000 m-3 in & Rcaron;& iacute;mov Reservoir (2018), and 88.8 inds.1000 m-3 in & Zcaron;lutice Reservoir (2019). Catfish fed on phantom midges (Chaoborus sp.).
