Abstract: The study was done in laboratory for a period of 30 days to know the effect of unilateral eyestalk ablation (ULEA) on the ovaries of female freshwater prawn,
M. lamarrei lamarrei. Morphologically good looking and apparent healthy specimens of
M. lamarrei lamarrei (28- 35 mm) were selected for experimental work. ULEA was done by cutting one eyestalk (left) away at their bases with sterilized scissors. The result of study indicated positive effects of ULEA on ovarian maturation of female freshwater prawn,
M. lamarrei lamarrei. The microscopic examination of different sections of ovary of female prawn which were ablated showed post vitellogenic oocytes while as females with both eyestalks intact never developed beyond pre vitellogenic oocytes during the experimentation. G.S.I. also shows that much ovarian indices develop better and rapidly as compared to control and on the basis of these facts, it is concluded that eyestalk of
M. lamarrei lamarrei containing ovary inhibiting factor results in acceleration of ovarian maturation.
