Abstract

Aloe vera is a rich resource of antioxidants, vitamins, minerals, mineral acids and enzymes. Studies showed that Aloe vera can affect the physiology of reproduction in animals. The aim of this trial was to evaluate the effect of different levels of the ethanol extract of the Aloe vera plant on reproduction and growth performance in Xiphophorus helleri. Powder extract was added to the diet in 4 levels: 200, 400, 800 and 1600 mg/Kg and control group without any extract. At the end of the experiment the results showed that there were significant differences in final weight, final length, weight gain, weight gain percentage and SGR in fish fed 800 mg/Kg compare to control group. Also, there were remarkable differences in the gonadosomatic index in treatment 4 and 5 than 1, 2 and 3. In conclusion, Aloe vera extract can improve the growth performance, fecundity and gonadosomatic index in Xiphophorus helleri.
