Abstract: This study (at 90 days) was carried out to evaluate the effect of feeding frequency on growth performance and survival rate Texas cichlid larvae (Herichthys cyanoguttatus). Four groups of texas cichlid larvae (average weight 0.5±0.11 g) designed with 4 feeding frequencies every other day (S1), 1 meal a day (S2), 2 meals a day (S3) and 4 meals a day (S4) with 3 replicates of each treatment combination were applied in this study. The Texas cichlid larvae in experimental treatments were fed by commercial food (Biomar) with 5% of body weight. Feeding frequencies had positive effect on growth performance (p<0.05). Final live weight and Specific Growth Rate (SGR) values of group S4 were significantly higher than those of the other groups (p<0.05). Similar responses were observed for Body Weight Increased (BWI) and Daily Growth Rate (DGR) and the best BWI and DGR were obtained in the S4 that showed significantly different to other groups (p<0.05). The best Feed Conversion Ratio (FCR) was obtained from four daily feeding (S4), however there were not significantly different between S4 and S3 (p>0.05). Also feeding frequencies had positive affect fish survival rate but it had not showed any significantly different between treatments. The best results in growth performance and survival rate were obtained by feeding 4 meals a day (S4) and some what in S3.
