Understanding the constraints and its related factors in tilapia (Oreochromis sp.) fish culture at farm level: A case from Bangladesh

Despite the enormous potential of tilapia farming in Bangladesh, its culture has yet to become established due to socio-economic, technical and marketing constraints. Tilapia culture is mostly concentrated in the Mymensingh region where a considerable number of fish farmers are involved in production. This study was conducted in Trishal sub-district under Mymensingh district to understand and analyze the constraints and its related factors in tilapia fish culture. Interviews were used to survey 100 households during October and November of 2017. Data were analyzed using descriptive statistics, rank order, coefficient of correlation, multiple linear regression and stepwise regression. Among seventeen constraints, lack of capital to invest in tilapia farming was identified as the most critical one, followed by high feed prices. The least important constraint faced by the farmers was the site selection for tilapia pond preparation. It was revealed that education, credit received, experience in fish farming, training experience and extension media contact of the farmers were significantly associated with the constraints in tilapia culture. Moreover, education, farm size and experience in fish farming were identified as significant determinants to the degree of constraints in tilapia farming. The study indicated some opportunities for the policymakers to address the influential factors (education, farm size and experiences in fish farming) of establishing tilapia farming. Additionally, credit facilities, proper training and suitable extension services could play a significant role in minimizing constraints in tilapia farming.
