This study employed stochastic frontier production function approach to investigate the technical efficiency and factors affecting the technical efficiency of shrimp farmers. With the aid of questionnaire, data were collected on farmers’ cost of major inputs (labour, seed, feed and lime), socio-economic activities, age, education, experience, household size and farm size, and on environmental hazards, flood and drought experience. The data was analysed using a stochastic production frontier. The result obtained revealed a mean technical efficiency of approximately 58%, reflecting that there exists a great potential for improving the efficiency of the shrimp production. The input variables considered in the model (feed, seed, labour and lime) were all found to be important factors for shrimp production in the area. In the inefficiency model, age, education, experience, drought experience and farm size were found to be positively related to technical efficiency. While flood experience was found to be positively related to technical inefficiency, drought experience was found to be negatively related to technical inefficiency. This study suggests a huge impact of pond adjustment on farmers’ cost of production, as 98% of the farmers reported to be adopting frequent pond adjustment and maintenance as an adaptation to frequent flood events. On the other hand, number of drought experience a farmer has was found to enhance his technical efficiency. Since all the inputs considered in this study were found to be positively related to the technical efficiency, this study therefore suggests the farmers be encouraged to increase their output by providing them the …
