This study explored the relationship between Industrial Policy on Fish Farming and Economic Growth in Nigeria (1990-2016). Specifically, it determined the type of relationship between Nigeria Federal Government subsidies on fish farming and real gross domestic product. Ordinary least square technique of regression was used for analysis of time series data generated from Federal Government statistical Bulletin and Bureau of Statistics. The study applied econometric model for estimating hypothesized relationship through causality and co-integration procedures. Findings revealed that there is a significant positive relationship between subsidies on fish farming and real gross domestic product. It is concluded that robust industrial policy on fish farming will enhance sustainable economic growth in Nigeria. Therefore, it is advocated that industrial policy on fish farming should consider in detail the long run nexus between fish farming subsector and other sectors of the Nigeria Economy.
