Influence of Dietary Organic Acids Supplementation on Reproductive Performance of Freshwater Angelfish ( Pterophyllum scalare )

摘要

A 2-month feeding trial was carried out with angelfish (3.45±0.05 g) by application of four dietsincluding commercial diet (control), commercial diet with 0.1% organic acids (T1), commercial diet with0.2% organic acids (T2) and commercial diet with 0.4% organic acids (T3) to investigate the proper dose andstudy the effect of organic acids on reproductive parameters. Experiment was conducted in a completelyrandomized design and data analysis was done by Excel and SPSS software packages. A significant difference(p0.05). There is no remarkable differencein hatchability among experimental treatments. Larval survival until yolk-sac absorption was higher in T1 thanother groups, significantly. To sum up, results indicate that it will be efficient to add 0.1% of organic acidssupplement to the angelfish diet because of promotion in reproductive parameters and increasing in larvalsurvival.
