Summary Automatic recording of the frequency of feeding ‘bites’ was used to evaluate the effects of several organic acids (citric, metacectonic, lactic, acetic, and oxalic) on the stimulatory feeding behavior of Tilapia nilotica . Some of these acids are added to food stocks to retard spoilage. The results showed that citric acid at a concentration of 10 −2 to 10 −6 m , metacetonic acid at 10 −4 to 10 −6 m , and lactic acid at 10 −2 to 10 −5 m stimulated feeding. Fish tended to avoid metacetonic acid at 10 −3 m and acetic acid at 10 −3 m . Acetic acid at 10 −5 m and oxalic acid at 10 −6 m had no significant effects on fish feeding.
