Comparative Technical Efficiency Of Concrete And Earthen Pond In Oyo State-Nigeria

Abstract

The study analysed the technical efficiency of earthen and concrete ponds in Oyo State from a sample of 80 earthen fish farmers and 120 concrete fish farmers selected from two Agricultural zones in Oyo state given a grand total of 200 fish farmers using Data Envelopment Analysis (DEA) approach to analyse the technical efficiency of earthen and concrete ponds under the Constant Return to Scale (CRS) and Variable Return to Scale (VRS) specifications. In order to identify the derterminants of earthen and concrete ponds inefficeinecy, a tobit analysis was conducted on the efficiency indices and suspected correlates of inefficiency. The average overall technical efficiency estimates obtained under the CRS and VRS specifications for earthen pond fish farmers are respectively 0.91 and 0.94. The mean overall technical efficiency estimates obtained under the CRS and VRS specifications for concrete pond fish farmers are 0.93 and 0.97. The study concluded that substantial inefficiency in earthen and concrete ponds occurred in the area.
