Growth and Survival of Bilateral Eyestalk Ablated Small Male Freshwater Prawn Macrobrachium rosenbergii (DeMan)

Effects of bilateral eyestalk ablation on molting and ovarian development in the giant freshwater prawn, Macrobrachium rosenbergii

In the present study, the effects of bilateral eyestalk ablation on molt interval, ovarian development, and hemolymph levels of ecdysteroid and vitellogenin were investigated in the giant freshwater prawn, Macrobrachium rosenbergii in order to examine the roles of the eyestalk hormones. In destalked males and females, ecdysteroid levels increased rapidly, and molt intervals were significantly s...

Genetic Inheritance of Female and Male Morphotypes in Giant Freshwater Prawn Macrobrachium rosenbergii

Giant freshwater prawn (GFP) Macrobrachium rosenbergii is unique with males categorized in five different morphotypes (small claw, orange claw, blue claw, old blue claw and no claw males) and females in three reproductive statuses (mature ovary, berried and spawned females). In the present study we examined genetic inheritance of female and male morphotypes, their body weights and genetic assoc...

Growth Promoting Potential of Garlic, Ginger, Turmeric and Fenugreek on the Freshwater Prawn Macrobrachium Rosenbergii

A 60 day feeding trial was conducted to determine the growth performance of Macrobrachium rosenbergii post larvae (PL) on Allium sativum (Garlic), Zingiber officinale (Ginger), Curcuma longa (Turmeric) and Trigonella foenum-graecum (Fenugreek) incorporated diets. Survival rate (SR) ranged from 69.0-80.0% in experimental diets fed PL groups were recorded against 66.0% in control. The elevation i...
