Abstract: Productivity of Tilapia farmers in northern Nigeria was studied among small-scale fish farmers in Kano State, Nigeria. Data were collected from 14 farmers using purposive sampling technique, which include only Tilapia farmers. Data were analyzed using descriptive statistics, budgeting technique and production function analysis. Results showed that Tilapia farmers make a Net Income of 140,000 ($1,000) ha ¹ of Tilapia-catfish production. For every kg of feed, farmers realized 5.5 kg of fish for Tilapia-Catfish. Total numbers of seed/fry and pond size were the major determinants (1% significance level) of the quantity of fish realized on the farm. Farmers were observed to still be making positive profits even with a 100% increase in critical input prices. The major limiting factors towards profitable Tilapia production in the area include lack of proper infrastructure, limited market, lack of effective extension service and shortage of good quality of cultivable fry. In order for farmers to increase their profit margin and thus alleviate their poverty, they have to increase the quantity of feed, fertilizer and lime use.
