The experiment consisted of three treatments in triplicates, i.e. catfish monoculture as the control (treatment A); catfish-prawn co-culture at a prawn density of 20prawn/m2 (treatment B) and catfish-prawn co-culture at a prawn density of 40prawn/m2 (treatment C). Catfish was reared in a bamboo cage inside experimental concrete ponds at an initial density of 100/m2. Commercial feed pellets were only offered to the fish. In treatments B and C, organic carbon was added at an estimated C/N ratio of 10 to stimulate biofloc growth as the food source for the prawn juveniles. There was no significant difference in catfish growth among treatments. Dissolved inorganic nitrogen concentrations in B and C were generally lower than in the control. Although significantly affected by the initial stocking density, prawn growth was comparable to that fed with formulated feed. Catfish co-culture with prawn with C organic addition resulted in significantly higher feed nitrogen utilization. Overall results suggest that catfish-prawn co-culture with C organic addition may improve total food conversion ratio, reduce nitrogen waste and generate additional income for catfish farmers.
