A multistage random sampling technique was used to select 256 catfish farmers in order to evaluate the technical efficiency of catfich production by large and small scale farms in Anambra State, Nigeria. The translog stochastic frontier production function approach was used to analyse data collected from 204 questionnaires. The technical efficiency scores were 0.89 and 0.94 for large and small scale farms, respectively. It means that the small scale farms are technically more efficient than the large scale ones, but the large scale farms possess higher capacity (11%) for expansion than the small scale farms (6%).
