Effects of bilateral eyestalk ablation on gonadal maturity, moultingand biochemical changes in the hemolymph of femalecrabs (Decapoda, Brachyura, Potamidae)Potamon

The gonadal and hepatic indices of the ablated crabs were significantly increased and decreased, respectively, at the end of the second week compared to the control groups (p < 0.05). The mean body weight of the ablated crabs was increased significantly at the end of the second and fourth weeks compared to the control group (p < 0.05). No significant change was observed in the mean carapace length of the ablated crabs at the end of the second week, but it had increased significantly by the end of the fourth week compared to the control group (p < 0.05). The ablated crabs moulted four weeks after the removal of their eyestalks, but no precocious moulting was observed in the control group
