Eyestalk ablation is the most common procedure used to induce crustacean reproduction in commercial hatcheries. However, other physiological and metabolic processes are affected by the removal of the X-organ sinus gland complex located in the eyestalk. In this study, the effect of unilateral eyestalk ablation on the concentration of several hemolymph metabolites, reproduction and immune function in female Macrobrachium americanum was investigated. Molting cycle time was not significantly (P=0.17) shortened in eyestalk-ablated females. However, an increased number of molts was observed in the eyestalk-ablated group because survival was significantly higher due to increased passivity and lowered aggression. As M. americanum has closed thelyca, reproduction was not accelerated after eyestalk ablation compared to control prawns. Food intake (P=0.007) and oxygen consumptio.. View More»
