This study assessed the fish production, culture facilities, operations, water resource management and profitability of fish farming in Katsina State, Nigeria, with a view of understanding the status of aquaculture development in Katsina State. Data were collected using structured questionnaire administered to 35 out of the active 42 farms in Katsina State at the period and the data obtained were analyzed using descriptive statistics and linear regression. Among the respondents, 37.1% used concrete tank alone and another 37.2% used concrete tank with other types of culture facilities, 57.1% practised mono-culture techniques and 77.1% used stagnant renewal system as culture system. Management of water quality was done by majority (82.9%) with mere visual evaluation, while 68.6% did not use any forms of water treatment. Most of the farms (80%) depended on imported feed for feeding their fish and gross profits of?7.29±1.81 and ?157.83±118.08 were obtained on fingerlings and adult fish, respectively. The tested explanatory variables were responsible for 45.4% change in profitability and profitability was found to be dependent on feeding cost (t=–3.38 and p=0.002) and size of fish at harvest (t=2.70 and p=0.011). The research findings established that fish farming in Katsina State was under developed.
