Introduction: India is rich in freshwater aquaculture resources that includes 2.35 million hectare of ponds and tanks, 1.3 million hectare of oxbow lakes and derelict waters, 0.19 million km of rivers and canals, 3.15 million hectare of reservoirs that could be utilized for aquaculture. Ponds and tanks are the prime resources for aquaculture, however only about 0.8 – 0.9 million ha is used for aquaculture currently. The total aquaculture production of 2.47 million tones that constitutes 4.2% of global production was valued at US$ 2.9 billion [1]. If aquaculture is to play a vital role in ensuring future fish availability for food security and nutrition in India, this sector has to develop and grow in an economically viable and environmentally sustainable fashion.
Abstract
A stochastic frontier production function model was utilized to estimate the technical efficiency of carp farms operating in Kolleru Lake area that is the largest freshwater wetland ecosystem with shallow water area covering 955 sq. km upto 10.7’ contour located in between Krishna and Godavari delta of southern India. Analysis was based on sample of 221 carp farms. The estimated mean technical efficiency (TE) was found to be 0.7260. The highest significant elasticity of coefficient was observed for feed (0.2001) followed by organic manure (0.1411) justifying the importance of these two inputs in yield of carps. The empirical results suggest that there are significant possibilities to increase efficiency levels by increasing pond size, provision for regular supply of fresh water, right method of application of drugs, employing labour on regular basis and leasing out the water bodies to farmers whose primary occupation is fish farming and educating the farmers to procure seed from reliable sources, to follow proper harvesting technique and avoiding periodical netting. Analysis of potential TE improvement of aquaculture farms reveals that if the average farmer in the sample was to achieve the TE level of its most efficient counterpart then the average farmer would realize an 26.7 percent cost saving. A similar calculation for the most technically inefficient farmer revealed a cost saving of 48.9 percent. Differences in efficiency levels are identified and explained with respect to various farm specific variables having impact on TE through estimating a model for technical inefficiency effects. The study suggests that with the same level of input, there is potential to enhance the yield to the the extent of 27.40 percent through efficient use of resources.
