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 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...
متن کاملVitellogenesis during the ovarian development in freshwater female prawn Macrobrachium rosenbergii (De Man)
In the present investigation, vitellogenesis during ovarian development in the freshwater prawn Macrobrachium rosenbergii was assessed. Ovarian development was classified into five stages based on size, colour and texture of ovary. Interestingly, histological results clearly indicate that the oocyte development gradually increased from stages I to V based on the yolk material accumulation. Besi...
متن کاملTolerance of Macrobrachium rosenbergii to white spot syndrome virus
The susceptibility of Macrobrachium idella, M. lamerrae and M. rosenbergii to white spot Ž . syndrome virus WSSV was tested by immersion challenge, oral route and intramuscular injection. Their susceptibility to WSSV was compared with that of Penaeus indicus and P. monodon. The WSSV caused 43.3% and 53.3% mortality in M. lamerrae and M. idella, respectively, by immersion method and 53.3% and 66...
