This study was conducted to evaluate the effect of feeding methods by hand and by using self feeder, respectively, on the feed efficiency and production of common carp (Cyprinus carpio) in runing water ponds. Carp fingerlings with an average individual weigth of 68.18 g were stocked at a rate of 75 kg per pond with a surface area of (3x5) m2 and depth of 0.8 m. The water was allowed to flow continuously at a rate of 10 l/second. The fish were fed with pellet at daily rate of 4; 3,5 and 3 percent of total body weight for the first, second and third month respectively. They were fed for a period of 12 weeks. Fish which were fed by hand broadcasting were fed three times daily. For those fed by self-feeder, the total daily allowances was offered only once at 08.00 a.m. The results showed that the average weight of fish fed by broadcasting (288.38 g) was significantly higher (P0.05) than that fed by self-feeder (257.33 g). Likewise, the average net production per pond was significantly higher (P0.05) in the former (237.52 kg) than in the latter (206.00 kg). The feed conversion values were also significantly different (P0.05) and were 1.70 for the former and 1.87 for the latter.
