The oriental river prawn (Macrobrachium nipponense) is mainly distributed in East Asia. The phylogeography, population genetic structure and historical demography of this species in the East Asia were examined by using partial sequences of the cytochrome oxidase subunit I (COI) and 16S rRNA in mitochondrial DNA. Ten populations that included 239 individuals were collected from Taiwan (Shihmen R...

Metabolic adjustment to hypoxia in Macrobrachium nipponense (oriental river prawn) implies a shift to anaerobic metabolism. Hexokinase (HK) is a key glycolytic enzyme in prawns. The involvement of HK in the hypoxia inducible factors (HIFs) pathway is unclear in prawns. In this study, the full-length cDNA for HK (MnHK) was obtained from M. nipponense, and its properties were characterized. The f...

Imidazole derivative KK-42 is a well-known regulator of insect growth. KK-42 pretreatment has been shown to promote the survival of Macrobrachium nipponense infected with Aeromonas hydrophila, possibly via activation of superoxide dismutase (SOD). In this study, the cytMnSOD gene was cloned from the hepatopancreas of M. nipponense using the rapid amplification of cDNA ends technique. The full-l...

To assess the genetic status of this species, the genetic diversity of wild Macrobrachium nipponense from seven geographic locations in the Yellow River basin were investigated using 20 polymorphic microsatellite DNA loci. The genetic diversity between populations was indicated by the mean number of alleles per locus and mean observed heterozygosity (H) and the expected H, which was arranged fr...

Abstract Data on the distribution, abundance, biomass, and morphological features of Macrobranchium nipponense from 1986-2022 collected in Republic Moldova are presented. Maximum length Macrobrachium was 117 mm, which is bigger than other places, maximum weight 13.8 g. The highest abundance 12 individuals/m 2 . M. dispersed place introduction a distance 210 km. most probable pathways dispersal ...

Semicarbazide (SEM) is the metabolite of the illegal veterinary nitrofurazone (NFZ) in aquatic animal. However there are increasing occurrences that SEM has been found in Macrobrachium Nipponese (M. Nipponese) prawns during the routine quality controls testing for aquatic food in China since 2008. To ascertain the presence and source of SEM, prawn samples were collected from different resources...

Temperature is an essential environmental factor affecting the viability of organisms. changes could cause damages or even death. The oriental river prawn, Macrobrachium nipponense, widely distributed in East Asian countries, and has been important economical aquaculture species China since 1990s. This prawn belongs to crustaceans, which a kind ectotherms very sensitive temperature due their re...
