Description:	This study investigated the effects of diets supplemented with levamisole on monogeneans on the gills of Colossoma macropomum. Fish were fed with diets containing levamisole at concentrations of 0, 300, 600, 900 and 1200 mg kg-1 for 24, 96 and 240 h and the infection by Anacanthorus spatulatus, Notozothecium janauachensis and Mymarothecium boegeri were evaluated. None of the levamisole concentrations caused either mortality or behavioral alterations in fishes during 240 h of feeding. After 24 h of feeding with 1200 mg kg-1 of levamisole, the abundance of N. janauachensis decreased in comparison with treatments of 0, 300, 600 and 900 mg kg-1, as did the abundance of M. boegeri after 240 h of feeding with 1200 mg kg-1 of levamisole. The efficacy of 900 mg kg-1 of levamisole was only 55.7% after 96 h of feeding, but it was 84.6% after 240 h of feeding with 1200 mg kg-1. Our results show that 1200 mg kg-1 of levamisole for 10 days has good anthelmintic efficacy against monogeneans of C. macropomum. Since monogeneans elicit some of the worst problems in C. macropomum, this study has provided evidence of an effective control method that may be used in fish farms.
