Effect of dietary astaxanthin on growth and immune response of Giant freshwater prawn Macrobrachium rosenbergii (de man)

Use 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...

Effects of an organophosphorus insecticide, trichlorfon, on hematological parameters of the giant freshwater prawn, Macrobrachium rosenbergii (de Man)

Hemolymph osmolality, ion concentration, acid–base balance, and immune parameters in Macrobrachium rosenbergii (15–20 g) were measured after 8 days of exposure to 0–0.3 mg l 1 trichlorfon. A significant depression in hemolymph osmolality and Cl 1 contents were observed with exposure to 0.3 mg l 1 trichlorfon. Similarly, hemolymph pH, HCO3 , and TCO2 decreased significantly when prawns were expo...

Transcriptomics of a Giant Freshwater Prawn (Macrobrachium rosenbergii): De Novo Assembly, Annotation and Marker Discovery

BACKGROUND Giant freshwater prawn (Macrobrachium rosenbergii or GFP), is the most economically important freshwater crustacean species. However, as little is known about its genome, 454 pyrosequencing of cDNA was undertaken to characterise its transcriptome and identify genes important for growth. METHODOLOGY AND PRINCIPAL FINDINGS A collection of 787,731 sequence reads (244.37 Mb) obtained f...

Pathogenicity of Aeromonas hydrophila in giant freshwater prawn Macrobrachium rosenbergii, cultured in East Malaysia

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...
