This study investigates production and cost efficiency as well as economic efficiency of fish farming. The study is based on primary cross sectional data collected from 6 Local Government Area (LGAs) selected from the 6 states that make up the of South-Western zone of Nigeria, on a representative basis of one local government per state. The farmer’s economic efficiencies are estimated as the product of TE and AE. The production technology of the farmers is assumed to be specified by the Cobb-Douglas frontier production function. Findings from the results indicate that a unit increase in use of feed, high stock density, quantity of lime and organic fertilizer used will increase fish output by 3.37, 0.75, 0.06 and 0.69%, respectively. The study reveals that fish farming operation in the study area is yet to achieve the maximum possible efficiency level. The results indicate that involvement in fish farming under high level of productive efficiency will increase fish supply in Nigeria, thereby reducing fish importation with an attendant improvement in the value of Foreign reserve and by extension stability in the Foreign exchange value.

This study investigates the supply response and elasticity of selected staple food crop in Nigeria: evidence from FAO, 1995-2017. The study is based on secondary data source from Food and Agricultural Organization (FAO). The time series data was sourced from 1970-2015. Supply response in agriculture presents the agricultural output response to changes in agricultural price and all agricultural incentives, therefore, this study investigated the yield response of maize to price change for over 20 years. The highest production of maize was recorded in Kaduna, Niger and Taraba State of Nigeria while the lowest acreage cultivated to maize was found in Lagos and Bayelsa. The results shows that the relationship between the short run and long run elasticity for output response of maize is negatively inelastic. This shows that it is not price responsive.
