There currently is more and more interest in the use of natural products, such as tea polyphenols, as therapeutic agents. The polyphenol compound pyrogallol has been reported before to inhibit quorum-sensing-regulated bioluminescence in Vibrio harveyi. Here, we report that the addition of 10 mg · liter(-1) pyrogallol protects both brine shrimp (Artemia franciscana) and giant river prawn (Macrob...

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...

MicroRNAs (miRNAs) have important roles in post-transcriptional regulation of gene expression. During viral infection, viruses utilize hosts to enhance their replication by altering cellular miRNAs. The Janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathway plays crucial roles in the antiviral responses. In this study, two miRNAs (miR-9041 and miR-9850) from Macrobra...

Giant freshwater prawn, Macrobrachium rosenbergii (deMan) (Crustacea-Decapoda) is an economically important species widely cultured in both freshwater and low saline water (brackish water) aquaculture. The experiments were conducted to study the effects of dietary supplementation of vitamin-E on the post-larval production (seed production), lipid peroxidation (LPX) and antioxidant defence syste...

Effect of stocking density on growth, biomass increase and survival of postlarvae of Macrobrachium rosenbergii were evaluated in cages fixed inside an earthen pond. In the primary Ž . nursery phase, newly metamorphosed postlarvae PL were stocked for 20 days at densities of 2, y1 Ž . 4, 6, 8 and 10 PLs l . In the secondary phase 60 days , the densities tested were 100, 200, 300, 400, 600 and 800...

The growth rate and mortality of giant prawns (Macrobrachium rosenbergii) in the Kuala Cenaku River, Indragiri Hulu Regency, Riau Province were carried out based on carapace length frequency data collected from May to July 2020. This study aims at River. For estimating dynamic population, analysed by using FiSAT II. parameter tiger shrimp was 0,78/year with asymptotic (L) 84,8 mm, total (Z), na...
