A simple device for the separation of weak larvae of Macrobrachium rosenbergii (De Man)
Larvae of Macrobrachium rosenbergii (De Man) are photopositive (Ling 1969a.b) and negatively rheotactic. While investigating larval diseases of M, rosenbergii it was observed that weak larvae failed to show both these responses. It was felt that this lack of response could be used to develop a device for separating the weak larvae from the apparently healthy ones. Such a device would be a valua...
متن کاملIsolation of a pathogenic strain of Vibrio alginolyticus from necrotic larvae of Macrobrachium rosenbergii (de Man).
Giant freshwater prawn, Macrobrachium rosenbergii (de Man), is an important commercial species with considerable export value, ideal for cultivation under low saline conditions and in freshwater zones (Kurup 1994). However, despite more than a decade of research on its larval production systems, vibriosis still hampers seed production resulting in high mortality rates. Among the different speci...
متن کاملUse of Brewer’s Yeast Saccharomyces cerevisiae as Growth Promoter in Giant Freshwater Prawn (Macrobrachium rosenbergii de Man) Post Larvae
A feeding trial was conducted for 75 days to study the effects of live brewer’s yeast (Saccharomyces cerevisiae) on growth and body composition in post larvae of the giant freshwater prawn, Macrobrachium rosenbergii (de Man). Five diets were formulated containing optimum protein level of 35.24±0.04. These experimental feeds were supplemented with 0.0% (control diet), 0.1%, 0.2%, 0.5% and 1.0% l...
متن کاملThe effect of abiotic factors on the hatching of Moina micrura Kurz, 1874 (Crustacea: Cladocera) ephippial eggs.
The roles of some abiotic factors in controlling the hatching rates of Moina micrura ephippial eggs were investigated. Determination of optimum hatching conditions would be important in developing the use of this species as a food for fish larvae in aquaculture. Ephippia were exposed to different treatments in the laboratory, and monitored for hatching over a period of seven days. Optimum hatch...
متن کاملChitosan Nanoparticles for Gene Delivery in Macrobrachium Rosenbergii (de Man 1879)
The present study demonstrates non viral gene delivery using chitosan nanoparticles in Macrobrachium rosenbergii as model organism. Chitosan nanoparticles were synthesized by ionic gelation method. The mean particle size of chitosan nanoparticles was 27.6nm. The Polydispersity index was found to be 0.448 and zeta potential was +24.79mV. Green fluorescent protein encoding plasmid (PDB-402) was u...
