Abstract
The effect of unilateral eyestalk ablation in freshwater prawn Macrobrachium lamarrei lamarrei was studied. The removal of the eyestalk has promotted the gonad development. In the present study an increase in the testicular and ovarian index in both sexes were observed in eyestalk ablated prawns as compared to normal animals. Thus our study indicates a positively co-related effect, of unilateral eyestalk ablation and is sufficient to induce gonadal development in Macrobrachium lamarrei lamarrei.
