Impact of technology intervention on fish productivity and profitability of fish farming in South Tripura

Impact of fisheries technology intervention by Krishi Vigyan Kendra (KVK), South Tripura was assessed in terms of fish productivity and profitability in the intervened villages of the district. The study prepared the model of ‘Difference in differences’ (DiD) estimator in a regression framework to estimate the changes in dependent variables. Non-random longitudinal data collected from 68 farmers (categorized as beneficiary: 33 nos. and non-beneficiary: 35 nos.) were used to estimate the DiD model for both fish productivity and profitability within the time passage of 2014 to 2018. Regression model framework estimated the non-standardized DiD coefficients as 124 and 5460 for productivity and profitability model respectively. It implies that the expected mean change in the fish production and profitability of beneficiary farmers (treatment group) was 124 kg/ acre/ yr and Rs. 5460 per acre/ year respectively due to technological intervention over the mentioned time passage after due consideration towards the same among nonbeneficiary farmers (control group). Overall, the study concluded a positive impact of fisheries technology intervention of KVK, south Tripura on fish productivity and profitability in the district during 2014 to 2018.
