Past beneficiaries of research and extension projects in aquaculture in the USA have been large farmers using pond culture systems. Additional studies, based on sound knowledge of empirical behaviour, are needed to identify alternative technologies and aid in the management decisions of small‐scale farms. A mixed integer, multiperiod linear programming model and survey data were used to analyse the profitability of caged channel catfish, Ictalurus punctatus (Rafinesque), culture. Results suggest that only a limited number of farmers may be able to adopt cage culture as an alternative farm enterprise. Profitability was sensitive to assumed product prices.
