This study examined the factors affecting productivity and constraints of commercial tilapia farms in the Dangme West District of the Greater Accra Region of Ghana. Primary data was obtained from 41 tilapia farms using multistage sampling. The data was then analyzed using descriptive statistics and regression analysis, and the agreements within ranked constraints was assessed. The empirical results revealed that the tilapia farmers in the three towns from which the data were collected, namely Achavanya, Kajanya and Dormeliam, produced a mean output of 74 kg per cage (6 m × 6 m × 3 m) as a productivity measure. Productivity of the cage farms were found to be positively affected by quantity of seed, feed and education level of managers; and negatively affected by cage size, labour and year of experience. Furthermore, the major constraints identified were high cost of inputs, lack of access to feed and credits and in adequate extension services and stealing of fish. The study suggests the need for supporting policies on inputs such as fingerlings and feed, and also providing education i.e. training to tilapia farmers. Efforts should also be made by financial institutions and NGOs to make credit easily available and accessible to commercial fish farmers so that they could cope with high cost of inputs. © 2016 Kasetsart University
