Abstract
Shrimp farming is a key subsector of Indian aquaculture which has seen a remarkable growth in the past decades and has a tremendous potential in future. The present study analyzes the technical efficiency of the shrimp famers of East Godavari district of Andhra Pradesh using the Stochastic Production Frontier Function with the technical inefficiency effects. The estimates mean technical efficiency of the farmers was 93.06 % which means the farmers operate at 6.94 % below the production frontier production. Age, education, experience of the farmers and their membership status in farmers associations and societies were found to have a significant effect on the technical efficiency. The variation in the technical efficiency also confirms the differences in the extent of adoption of the shrimp farming technology among the farmers. Proper technical training opportunities could facilitate the farmers to adopt the improved technologies to increase their farm productivity.
Highlights
Coastal shrimp aquaculture in a traditional form existed in Indian sub-continent for many centuries
The amount of labour used for production was expressed in terms of salaries and wages paid for permanent labour as well as hired labour utilized for specific activities such as pond preparation and other regular activities
From the study it is clearly evident that farmers were technically efficient and they could achieve 93.06 % of the potential yield in East Godavari
Summary
Coastal shrimp aquaculture in a traditional form existed in Indian sub-continent for many centuries. During eighties the shrimp farming enterprise picked momentum and became a popular farming practice among coastal farmers. It was in the 1990s, the economic liberalization process widened the scope of the commercial shrimp farming since it was arosean export oriented activity. The government schemes and programmes fueled the growth in subsequent years and the shrimp farming become a very important sub-sector of the fisheries domain. Shrimp farming is dependent on various factors like quality of the physical characteristics of the system, climatic conditions and essentially the quality of all the input resources that areused in the production process. The shrimp yield is a function of different factors. The variation in the yield and the factors responsible for the inefficiencies has to be studied in detail to improve the production and productivity of the farms and our farming systems can achieve maximumefficiency
