Resumo: The rhythm of movements and feeding activity of juveniles of Loricariichthys anus (Valenciennes, 1840) in the Quadros lake, South Brazil, are investigated. Between October 1997 and August 1998, 236 specimens were captured during six bimonthly 24 hour gillnet surveys. Significantly elevated levels of movement and feeding activity during the day are registered. The patterns of movement and feeding activity displayed no significant difference, suggesting that high movement activity levels can be attributed to feeding activity. The mean of the intestinal quotient was 1,89, indicating omnivorous feeding habits.
