Effects of Eyestalk Ablations on Growth and Ovarian Maturation of the Freshwater Prawn Macrobrachium lanchesteri (de Man)
Abstract
The effects of unilateral and bilateral eyestalk ablations on growth, ovarian maturation, carbohydrate, protein and energy contents were investigated in Macrobrachium lanchesteri (de Man). Daily growth as well as ovarian maturation were accelerated by eyestalk ablation in these prawns. The mortality in ablated prawns was more than that of intact ones. The biochemical components like carbohydrate and protein were altered by eyestalk ablations. The energy content of the different tissues were also showing some variations due to the absence of eyestalk hormones. Eyestalk ablation, especially unilateral eyestalk ablation could be used for inducing rapid growth and spawning in this particular species of freshwater prawns.
