Effect of feeding frequency on the growth and survival of Himri Barbel Barbus luteus (Heckel, 1843), fry under laboratory conditions

Abstract

The effect of feeding frequency on the growth performance, feed conversion ratio and survival of Himri Barbel, Barbus luteus, was investigated. Thirty fry (0.26±0.03 g) were stocked in 12 (80-L) (80×40×40 cm) aquaria and fed 3, 4, 5 and 6 times a day respectively for 60 days. Final body weights and SGR were measured significantly lower at D (6 times/day) and C (5 times/day) than B (4 times/day) and A (3 times/day) treatments (p<0.05). There were no significant differences for the FCR and survival rates (p>0.05). The results showed that weight gain and growth performance of Himri Barbel, B. luteus, fry were decreased with increased feeding frequency. © Asian Network for Scientific Information, 2008.
