A decision support system to assist cage aquaculture managers is presented. The system enables managers to perform four essential tasks: (i) site classification, (ii) site selection, (iii) holding capacity determination, and (iv) economic appraisal of an aquaculture farm at a given site. Based on measurements of water and substrate qualities, hydrometeorology and socioeconomic factors, a cage a...

Results: The study showed wide variation across different farm sizes with respect to total economic cost and net return per 100 lb (45.4 kg) of live hog produced. The total economic cost was negatively correlated (r = -.318, P = .016) and net return was positively correlated (r = .336, P = .011) with farm size. The average net return for large herds (> 75 sows) was higher (P =.003) than for sma...
