Pelagic distribution and night foraging of early juvenile European catfish ( Silurus glanis L .)

Year: 2025

Type: article

Abstract: 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 −3 in Klíčava Reservoir (2018), 0.3 inds.1000 m −3 in Římov Reservoir (2018), and 88.8 inds.1000 m −3 in Žlutice Reservoir (2019). Catfish fed on phantom midges ( Chaoborus sp.).
