of inputs. The use of stochastic frontier analysis enables ranking of the carp
culture farms based on efficiency of yield of fish, enabling identification of the
most efficient and inefficient farms across various carp farming system operating
in the Kolleru lake area. The efficient farms may serve as a model farm for
improving the efficiency of carp production, 'in the kolleru lake area as well as
throughout the whole country where the mean technical efficiency is reported to
be lower (Sharma and Leung, 2000b). The empirical results suggest that there
are significant possibilities to increase efficiency levels by extending culture
operation in large size ponds, provision for supply of fresh water, application of
drugs aRer diluting in water, employing labour on a permanent basis, leasing out
the water bodies to farmers whose primary occupation is fish farming, educating
the farmers to procure seed from reliable sources, proper harvesting techniques
and avoiding periodical netting. From the policy point of view, the above farm
specific variables were found to be most promising areas for action, suggesting
that policy makers should consider those factors for possible programs at
enhancing the productivity without any additional input use. Further studies
involving allocation of resources, cost efficiencies are needed.
