Abstract : A study was undertaken to ascertain constraints faced by fish farmers in adoption of scientific aquaculture practices in East Champaran and West Champaran districts of Bihar. Information from 144 respondents was collected and analysed by calculating the Rank Based Quotient (RBQ) values. RBQ value for constraint faced by farmers were extreme climatic conditions (84.03), less extension programs and technical support (78.47), lack of contact with extension personnel’s (71.33), lack of awareness about scientific culture practices (65.28), inadequate credit facility (60.42), labour scarcity (57.64) and higher cost of material input (52.08).These constraints could be categorised under five heads namely extension constraints, financial constraints, production constraints, marketing constraints and social constraints. Average RBQ value for constraints related to extension was found to be 71.76 and ranked first. This was followed by financial constraint with RBQ value of 52.78. Production related constraint ranked third with an average RBQ value of 49.3 followed by marketing (32.87) and social constraints(27.08). Hypothesis that there is no significant difference with reference to rankings of constraints was tested by single factor ANOVA. Null hypothesis was rejected as Ftab=3.48>FNcal=2.61 with df=4 at 5% level of significance. There was a significant difference with reference to rankings of constraints. As the extension related constraints had the highest average RBQ value, it is clear that there is an urgent need of making effective strategy, engaging more fisheries extension professionals in this field along with capacity development of the existing extension professionals..
