A field survey through questionnaire was conducted in rice-prawn (Macrobrachium rosenbergii)-fish culture ghers six villages of Khulna, Satkhira and Bagerhat districts south-west Bangladesh during March to December, 2008 assess present practices. About 10-25% the total area land converted for building canals dikes remaining were used rice cultivation. Boro with prawn fish appeared have positive...

macrobrachium rosenbergii lifecycle is unique so that the adults thrive in freshwater and larval development requires brackish water environments near to estuaries as close as possible to larval body isosmotic for minimum na/k-atpase activity and maximum atp storage. osmoregulation system at early larval stages is not formed and larval osmoregulation is mainly attributed to na/k-atpase activity...

The chemical composition and microbial burden of freshwater prawn was determined at different storage temperatures (00C, 4±10C, 28±20C) for 5 days using standard microbiological techniques. Microbial isolates found in samples include: Staphylococcus aureus, Bacillus spp., Proteus mirabilis, Escherichia coli, Pseudomonas aeruginosa, Salmonella spp. Aspergillus flavus. proximate analysis carbohyd...

The fresh water prawn, Macrobrachium rosenbergii, has proven potential for use as an aquaculture species (Hanson & Goodwin, 1997; Kurup, 1984). In India alone, culture of this species of prawn in low saline areas requires about 200 million seed per year (Kurup, 1984). In hatcheries poor survival rate has been associated with vibriosis at different stages of the larval cycle. Members of the fami...

Udang galah (Macrobrachium rosenbergii) merupakan komoditas perikanan yang potensial untuk dibudidayakan karena pertumbuhannya cepat, berukuran besar, serta tingkat prevelansi penyakit rendah. Faktor utama perlu diperhatikan dalam pembenihan Galah adalah pemilihan induk, pemeliharaan calon metode pemijahan, manajemen pakan, pengendalian hama dan penyakit, kualitas air. Dengan demikian, kegiatan...

Shrimp aquaculture environments are a natural reservoir of multiple antibiotic resistance genes (ARGs) due to the overuse antibiotics. Nowadays, prevalence these kinds emerging contaminants in shrimp is still unclear. In this study, high-throughput sequencing techniques were used analyze distribution ARGs and mobile genetic elements (MGEs), bacterial communities, their correlations water sedime...
