Yellow head virus (YHV) is an invertebrate nidovirus which causes a severe mortality in cultured Penaeus monodon. The mortality may be prevented by prior treatment of shrimps with YHV-protease dsRNA. Whether the YHV infected shrimp might be cured by the dsRNA remains to be investigated. P. monodon injected with 10(-6) YHV showed a high virus replication and mortality within 2 days. Injection of...

Hemocyanin sequences allineament shows the presence of highly invariant regions especially in the active site and in the tight intersubunits interaction sites. Comparing the aminoacids in contact regions between monomers is possible to interpret the stability of hexamers.

This study presents updated information on six exotic aquatic species (five crustaceans and one fish): Macrobrachium rosenbergii, Penaeus monodon, Charybdis hellerii, Balanus trigonus, Amphibalanus improvisus, Pterois volitans. The research is based bibliographic available in scientific articles published by the Research Group Fishing Evaluation of Tropical Fishery Resources Biological Photogra...

A study was carried out to evaluate polymerase chain reaction (PCR) for the detection of white spot syndrome virus (WSSV) in postlarvae and broodstock of Penaeus monodon and in potential crustacean carriers from India. Primer pairs designed for WSSV affecting Penaeus japonicus (WSSV PJ) and P. monodon (WSSV PM) were used. Both the primer pairs gave positive assay results for crustaceans showing...

During the present study average annual catch of Penaeus monodon during 2011 - 2013 was 281.29±9.67 ton, which contributed 0.41 % to total trawl net catches at Digha coast. The rate 43.41 kg/h. percentage P. shrimp 1.91% in landings Monthly mean were 28.13±0.97 t from nets. Peak observed June November with a maximum 56.46±1.97 September and lean December March minimum 6.12±0.21 t.

Two epizootics of cultured shrimp occurred in India in 1994. The first case of mass mortalities of tiger shrimp Penaeus monodon in July 1994 was very similar to that caused by yellowhead virus (YHV) infection with regard to gross clinical signs, host species and size of shrimp affected, but it was histologically atypical. Very interestingly, intranuclear inclusions typical of a white spot syndr...

Coastal aquaculture in Bangladesh consists mainly of two shrimp species (Penaeus monodon and Macrobrachium rosenbergii). Currently, there are about 16,237 marine shrimp (P. monodon) farms covering 148,093 ha and 36,109 fresh water shrimp (M. rosenbergii) farms covering 17,638 ha coastal area. More than 0.7 million people are employed in the farmed shrimp sector and in 2005-2006 the export value...

Viral pathogens appear to exert the most significant constraints on the growth and survival of crustaceans under culture conditions. The prevalence of viral pathogens White Spot Syndrome Virus (WSSV), Hepatopancreatic Parvo Virus (HPV), Monodon Baculo Virus (MBV) and Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV) in Penaeus monodon post-larvae was studied. Samples collected from ...

BACKGROUND Length-weight relationships and condition factors of giant tiger shrimp Penaeus monodon (Fabricius, 1798) from four breeding families (family S: South China seas family, family A: African family, family SA: ♂ South China seas family × ♀ Africa family, family AS: ♂ Africa family × ♀ South China seas family) were evaluated in this study. FINDINGS AND CONCLUSION Length-weight relation...
