MAT1 (ménage à trois 1), an assembly factor and targeting subunit of the CDK-dependent kinase (CAK), can regulate the cell cycle, transcription, and DNA repair. This study was intended to investigate the role of MAT1 in the reproductive maturation of black tiger shrimp (Penaeus monodon). In this study, the P. monodon MAT1 (PmMAT1) gene was identified and characterized. The full-length cDNA of P...

The two economically important shrimp species in Bangladesh are the tiger shrimp, Penaeus monodon, and brown Metapenaeus monoceros. However, a continuous decline landing of these from industrial trawling made it critical to assess their stock biomass status explore response present degree removal. Given minimum data requirement robustness, this study employed depletion-based reduction analysis ...

Juvenile shrimps (Penaeus monodon) weighing about 15-20 gms were procured from the grow-out ponds and reared under laboratory conditions. They were challenged with Vibrio parahaemolyticus MTCC 451 and their LD50 value was evaluated. The ascorbic acid and the histamine activity of both the control and experimental groups were assessed. The results showed a marked decline in both the parameters a...

Black tiger shrimp Penaeus monodon, European shore crab Carcinus maenas and spiny lobster Panulirus spp. can be affected by milky hemolymph syndrome (MHS). Four rickettsia-like bacteria (RLB) isolates of MHS originating from 5 geographical areas have been identified to date. The histopathology of the disease was characterized and a multiplex PCR assay was developed for detection of the 4 bacter...

The Black Tiger shrimp (Penaeus monodon) has a natural distribution range from East Africa to the South Pacific Islands. Although previous studies of Indo-Pacific P. monodon have found populations from the Indian Ocean and Australasia to differ genetically, their relatedness to South Pacific shrimp remains unknown. To address this, polymorphisms at eight shared microsatellite loci and haplotype...

Viral diseases are the most serious problem in shrimp culture as they result in severe production and economic losses. Monodon baculovirus (MBV) is a member of nucleopolyhedrosis virus (NPV) group that infect penaeid shrimps. Polymerase chain reaction (PCR) assays have been reported for specific and accurate detection of MBV. As variations in the strains of MBV would greatly affect the detectio...

the acute toxicity of a malaysian crude oil to red snapper, lutjanus argentimaculatus, blacktiger shrimp and penaeus monodon were investigated. the animals were exposed to water solublefractions (wsf) of crude oil in a flow-through bioassay system and the toxicants were analyzed by gaschromatography (gc) and gas chromatography and mass spectrometer (gc-ms). the 96 h lc50 valuesof the wsf of cru...

Black tiger shrimp, Penaeus monodon (Fabricius) is a non-piscine organism becomes most important aquatic resource of Bangladesh in the last decades. Traditionally it cultured 15-30 ppt salinity. Effect different low salinity on its survival, growth, production and economic return was observed three levels 10 ppt, 7 5 for 110 days. Juvenile shrimps (approximately 5g each) were stocked at 4 m-2 d...
