This study reports a primer set for amplifying a partial fragment of about 610 bp in the fast mutating mitochondrial control region in shrimps of the genus Penaeus (Decapoda: Penaeidae). The utility of this amplified fragment for studying population differentiation and structuring, compared with more conservative mitochondrial genes (16S rRNA and COI), was explored in P. merguiensis populations...

  White Spot Virus (WSV) is currently the most serious viral pathogen of shrimp worldwide it causes mortality up to 100% within 7-10 days in commercial shrimp farms. Infected Indian white shrimp Fenneropenaeus indicus samples were collected from Guatr shrimp site in Sistan and Baluchestan province in south of Iran and WSV infection was confirmed by Nested PCR. WSV was isolated from infected shr...

The susceptibility of Macrobrachium idella, M. lamerrae and M. rosenbergii to white spot Ž . syndrome virus WSSV was tested by immersion challenge, oral route and intramuscular injection. Their susceptibility to WSSV was compared with that of Penaeus indicus and P. monodon. The WSSV caused 43.3% and 53.3% mortality in M. lamerrae and M. idella, respectively, by immersion method and 53.3% and 66...

abstract background: fisheries safety control and considering heavy metal accumulation is one of the most important factors in maintaining health society and assuring the safety of this valuable food. the purpose of this study is evaluating the potential of bioaccumulation and exposure to lead and cadmium due to consumption of penaeus semisulcatus in tehran city 2012.. methods: samples were col...

Penaeus monodon (class Crustacea, order Decapoda) is one of the largest shrimps of the Penaeidea family from the Indo-West Pacific region. The dioxygen-transporting protein hemocyanin, isolated from the hemolymph of this invertebrate, is composed of three 75-76 kDa structural/functional subunits designated as Pm1, Pm2 and Pm3. The N-terminal sequences of the chains were determined and compared ...
