Macrobrachium rosenbergii popularly known as 'scampi' has been expanding in India recent years. Scampi farming gained momentum after the set-back in shrimp farming due to disease outbreaks and other factors. The infrastructure available to produce shrimp seed and process the shrimp was helpful in providing support to scampi farming. The existing culture system includes both monoculture and poly...

Phylogenetic analysis of representatives from 18 wild populations of the giant freshwater prawn, Macrobrachium rosenbergii, utilising a fragment of the 16S rRNA mitochondrial gene, identified two major reciprocally monophyletic clades either side of a well-known biogeographic barrier, Huxley's line. The level of divergence between the two clades (maximum 6.2%) far exceeds divergence levels with...

Lectins play important role in innate immunity of animals. The affinity of the natural haemagglutinin of the giant freshwater prawn Macrobrachium rosenbergii towards vertebrate erythrocytes and its level with relation to sex, size and moult stages were studied. The strongest agglutinating titres in haemolymph of prawns were marked against guinea pig, chicken, Clarias batrachus, and rabbit eryth...

The present study was conducted during June to December, 2010 with a view developing nursery technology respect stocking density optimization and survivability of prawn PL in earthen ponds. Hatchery obtained were reared commercial feed monitoring water quality for 14 weeks 12 ponds (1.25dec each) at Khulna University. Four densities viz., 958, 500, 800 1000 PL/dec used three replicates each. ra...

Aeromonas infections are becoming a major risk factor in commercial aquaculture and it has been reported that a wide variety of fish and shellfish species are susceptible to this infection. In this study, 3 isolates of Aeromonas hydrophila were isolated from giant freshwater prawn (Macrobrachium rosenbergii) cultured in Kuala Pilah Simbilan Nigri in East Malaysia. Conventional and rapid identif...

The decline of the freshwater prawn, Macrobrachium spp. in rivers can be attributed to overfishing, habitat loss and pollution. In order offset pressure, a community-based stock enhancement project was initiated by Borneo Marine Research Institute (BMRI), University Malaysia Sabah, increase number Petagas River, Putatan, Sabah. This study conducted determine distribution abundance different lif...

Behavioural toxicity is a very applicable area in the vast field of ecotoxicology where, assessment alteration behaviour an effective tool to evaluate neural activity organism. In our present study, we have shown that arsenic trioxide exposure can stimulate repetitive grooming freshwater prawn, Macrobrachium lamarrei; however, over time organism modulate performances less. We predict repetition...
