dc.description.abstract
Knowledge of the movements and diel behaviour of the
European catfish (Silurus glanis), the largest European freshwater fish, is
limited to anecdotal information. In a preliminary telemetry study of
European catfish, the spring diel movement patterns of five adult catfish
were examined. After intraperitoneal insertion of the acoustic tags, the
positions of the fish were recorded automatically in the Flix Reservoir
(River Ebro, NE Spain). A marked nocturnal mobility pattern was
observed throughout the study. During daytime, the catfish were
consistently located in the littoral zone and spent extended periods of the
day hidden in concealed habitats. Catfish movements were in a radial
pattern, with upstream and downstream excursions followed by returns to a
previously occupied location. Significant individual variations in
movement pattern were observed among the tagged fish and within the
24 h cycle for each fish. Mean instantaneous swimming speed was
0.17 body lengths per second (BLÆs)1) at night but 0.09 BLÆs)1 during the
daytime
