Effects of Synbiotic (Biomin Imbo) on Growth Performance, Survival Rate, Reproductive Parameters of Angelfish (Pterophyllum scalare)

Abstract

This study was carried out to evaluate the effect of synbiotic ( Biomin imbo ) on growth performance, survival rate and reproductive parameters of Angelfish ( Pterophyllum scalare ) via supplementation with Biomar. Four levels of Biomar experimental diets (54 % protein and 14 % lipid) were prepared by adding synbiotic (0.15, 0.5, 0.75, 1 g/Kg) at a basal diet (Biomar) and the Angelfish larvae in experimental treatments were fed four levels of synbiotic with 5 percent body weight (3 times a day). The larvae in the control treatment were fed without supplemented Biomar. The results showed that larvae fed on the synbiotic had significantly increased final body weight in comparison with the control treatment. After 90 days, 5 adult female and male Angelfish were divided from each treatment. The results showed that fecundity in experimental treatments increased in comparison with the control treatment. The synbiotic also had positive effects on hatching rate in comparison with those in the control treatment but, there were no significant differences (P > 0.05) among treatments. The synbiotic also had significant positive effects on the specific growth rate (SGR) and feed conversation efficiency (FCE) in comparison to those fed the control treatment, however treatment T3 was more than T4 (T3 > T4 > T2 > T1 > control treatment).
