Uttar Pradesh is India’s most populous state with enough fisheries resources in the form of community ponds, tanks with dominance of rivers and manmade reservoirs. Fish production in the state was only 0.62 million tonnes (2016-17). In this study fisheries resources of the state, trend of fish seed and fish production and their inter relationship were analysed. The study revealed that out of total available aquaculture resources of the state, only 48.97 percent were utilized for fish production and remaining 41.03% were unutilized. It indicates possibility of horizontal expansion in fish production. Further during 2001-02 to 2016-17 Average Annual Growth Rate (AAGR) in fish seed production and fish production was 7.67 % and 7.56 % respectively. The variability in production was about 32 %. The second order polynomial function in fish seed production (y = 6.524x2 - 42.87x + 1041) and fish production (y = 0.937x2 + 5.212x + 219.5) were best fit. Linear regression line of fish production on seed production (y = 0.249x + 29.88) indicates the fact that with increase of one million fry, fish production increases @ 0.249 thousand tonnes. A strong significant relation between two variables (r= 0.9223) justifying the advocacy of quality seed production for enhanced sustainable fish production in the state.
