Effects of Vitex agnus-castus extract on reproductive performance, growth and survival in Xiphophorus helleri

The present research studied the effect of different levels of ethanolic extract of Vitex agnus-castus on reproductive performance of Xiphophorus helleri. Productive fish fed diets containing different levels of Vitex agnus-castus extract, 0 (control or treatment 1), 750 (treatment 2), 1000 (treatment 3) and 1250 (treatment 4) mg/kg diet for 2 months. Fish fed diet containing of 1250 mg of Vitex agnus-castus extract significantly showed higher final weight, final length, weight gain index, weight gain and specific growth rate in comparison with control group (P
