As white spot syndrome virus (WSSV) can be highly pathogenic in penaeid shrimp, various feed supplements have been tested to help to protect farmed shrimp against WSSV disease. Here a polysaccharide extract from Halophila ovalis (HO) seagrass was added to feeds at concentrations of 0.25, 0.5, and 1.0 g[a1] /kg to assess its ability to protect Black Tiger shrimp (Penaeus monodon) against WSSV ch...
In this study, trypsin-like protease activity and expression of serine encoding genes (PmPPAE1, PmPPAE2 - clip-serine proteases PmTLP1, PmTLP2 proteases) in the different tissues black tiger shrimp were determined. The level PmPPAE1 was highest hemolymph; meanwhile that PmTLP1 hepatopancreas. hemolymph white spot syndrome virus (WSSV)-injected shrimp, PmPPAE1, upregulated by 2.32, 2.57 4.56-fol...
With regard to the importance of polychaete Perinereis nuntia in diet of shrimp broodstock, achieving its breeding and culture bio technique is an important goal in shrimp industry. For this purpose, usage of diets inducing the highest growth and the lowest mortality is of importance. The effect of four different dietary treatments including commercial shrimp diet- Biomar, Lansy shrimp diet con...
A comparative study regarding prevalence and antimicrobial susceptibility of Vibrio species in the black tiger shrimp (Penaeus monodon Fabricius) culture environment as well as market samples were analyzed. Total Vibrio counts were found to range up to 2.5 × 10 cfu/gm and 60 cfu/gm in shrimp and Gher water samples, respectively. Results revealed that the total vibrio count were found to be high...
The total haemocyte count (THC), phenoloxidase (PO) activity, respiratory bursts (release of superoxide anions), and superoxide dismutase (SOD) activity, as well as expressions of beta-1,3-glucan-binding protein (betaGBP), prophenoloxidase (proPO), peroxinectin (PE), cytosolic SOD (cyt-SOD), penaeidin-5 (PA-5), and a single whey acidic protein (WAP) domain protein (SWDP) gene were determined in...
White spot disease (WSD) which is caused by white spot syndrome virus (WSSV) creates severe epizootics in captured and cultured black tiger shrimp, resulting a huge loss in the economic output of the aquaculture industry worldwide. Performing selective breeding using DNA markers would prove to be a potential cost effective strategy for long term disease control in shrimps. In the present invest...
The protective efficacy of oral delivery of a DNA construct containing the VP28 gene of WSSV encapsulated in chitosan nanoparticles was investigated in black tiger shrimp (Penaeus monodon). The results showed that significant survival was obtained in WSSV-challenged shrimp at 7, 15 and 30 days post-treatment (relative survival, 85%, 65% and 50%, respectively) whereas 100% mortality was observed...
Onfarm trial were conducted to evaluate the effects of feeding on pellets with different protein levels in the presence and absence of the bioflocs on water quality, survival and growth of the green tiger shrimp (Penaeus semisulcatus) in intensive types of shrimp culture systems. Five different feeds were formulated. Four biofloc treatments (BFT) and one control were managed in 10 greenhouses e...
