Stable carbon isotope ratios (∂3C) and stomach contents were used to determine the diet of channel catfish (Ictalurus punctatus) and freshwater Malaysian prawns (Macrobrachium rosen-bergii) in polyculture. Catfish stomach contents were dominated by formulated rations. Macrophyte fragments and catfish ration were predominate in prawn stomachs. Catfish ∂13C ratios became lighter from June to October, which paralleled the change in ∂13C ratio of the formulated feeds fed to the fish. Prawn ∂13C… CONTINUE READING
