The nature of resources available and how they are combined and utilized in aquaculture largely determine its economic viability and social profitability. Using a novel Resource Cost Ratio (RCR), this study analyzes resource use efficiency and social profitability of an integrated aqua farm located in Tripura, India. RCR, a variant of the Domestic Resource Cost Ratio (DRCR), is the ratio of the net cost of non-marketable resources and the net value addition by using marketable resources. The RCR for the integrated farm was found to be -0.24. The negative value of RCR shows positive profitability for the integrated farm. The corresponding value for a specialized farm was found to be 0.52. The difference is the greater resource use efficiency of the integrated approach. Private and social profits per unit cost for the integrated farm (0.26 and 0.08, respectively) were higher than for the specialized farm (0.11 and 0.04, respectively). [ABSTRACT FROM AUTHOR]
