Inland low saline shrimp culture in Andhra Pradesh: profitability and resource use efficiency.

The study focused on investment, profitability, and input–output specific technical and scale efficiencies and suggested appropriately for its sustainable development in Andhra Pradesh. Farmers (n = 60) were interviewed, and data were analyzed using descriptive statistics, B-C ratio, C-D production function, and DEA techniques. The results depicted that majority of the farmers' primary occupation was aquaculture and 53% of them were farming on leased land. Yield (kg/ha) was highest for large farmers (5247 kg) followed by medium (5200 kg) and small farmers (4800 kg) which resulted the net incomes of $8771 for large farmers, medium ($7377), and small farmers ($6186). The share of feed cost and medicine cost was higher for large farmers, while feed and other costs were highest for medium and small farmers. Net returns were found to be proportional to the land holdings, while labor days have a negative effect. Inefficiency scores given by the DEA model suggest farmers were able to produce the same level of output with combination of inputs corresponding to the minimum cost of production. Adoption of scientific farming practices and CAA guidelines may ensure sustainable farm income. The DoF, AP has to frame policies for the promotion and monitoring of inland low-saline shrimp culture for the mutual benefit of all stakeholders. [ABSTRACT FROM AUTHOR]
