Larval Rearing and Post larval Production of Ganga River Shell Fishes Macrobrachium gangeticum and Macrobrachium malcolmsonii

Effects of larval stocking density and feeding ratio on larval rearing of giant freshwater prawn, Macrobrachium rosenbergii

Complete larval development of the Monkey River Prawn Macrobrachium lar (Palaemonidae) using a novel greenwater technique

This study documents the complete larval development of the Monkey River Prawn Macrobrachium lar using a new greenwater rearing technique. Approximately 6,000 larvae were reared for 110 days at an initial stocking density of 1 ind./6 L. Salinity at hatch was 10 ± 2 ppt and progressively increased to 30 ± 2 ppt until decapodids had metamorphosed. Temperature was maintained at 28 ± 0.5°C, pH at 7...

From lecithotrophy to planktotrophy: ontogeny of larval feeding in the Amazon River prawn Macrobrachium amazonicum

During downstream transport from rivers to estuaries, early larval stages of the Amazon River prawn Macrobrachium amazonicum (Heller 1862) are likely exposed to planktonic food limitation. In the laboratory, we studied the effects of presence or absence of food on larval survival, moulting and biomass (dry mass, and content of carbon, hydrogen and nitrogen). Unfed larvae developed successfully ...

Improved Post-larval Production in Giant Prawn, Macrobrachium rosenbergii, through Modulation of Antioxidant Defence System by Dietary Vitamin-E

Giant freshwater prawn, Macrobrachium rosenbergii (deMan) (Crustacea-Decapoda) is an economically important species widely cultured in both freshwater and low saline water (brackish water) aquaculture. The experiments were conducted to study the effects of dietary supplementation of vitamin-E on the post-larval production (seed production), lipid peroxidation (LPX) and antioxidant defence syste...

Role of algal mixture in Food intake of Macrobrachium rosenbergii during larval development

Possible roles of algae (i.e. “green water”) in facilitating Macrobrachium rosenbergii larviculture have been investigated in the present study. Three types of algae were mixted with shrimp larval feed. Algal members were belonging to the family like Cyanophyceae, Chlorophyceae and Charophyceae respectively. Algal mixture was applied with control feed, showed better result in shrimp larval deve...
