The analysis of integumental pore pattern has identified two intraspecific groups of postlarval shrimp Litopenaeus vannamei (Boone, 1931), a species of which three to five natural populations or groups are expected to be found from Mexico to Peru. Natural distribution and man-made redistributions have not been typified on a population basis in any penaeid, but it is important to do so in this c...

This study aims to determine of Chloramphenicol test for Vannamei shrimp conducted ELISA (Enzyme-Linked Immunosorbent Assay) method with 1 treatment. is done by adding the Abenzyme conjugate, and ends addition substrate reaction stop buffer. Each treatment was performed three times. The value (CAP) (Litopenaeus vannamei) which tested at 4 weeks ranged from 0.021 0.153 ppb. result showed in stil...

In this study, we identified a variable region in the C-terminus of hemocyanin from the shrimp Litopenaeus vannamei (2288-2503bp, HcSC) by sequence alignments. A total of 13 SNPs were identified by PCR-SSCP and HcSC clone sequencing. The SSCP patterns of HcSC could be modulated in Vibro parahaemolyticus-treated shrimps. A novel SSCP band with four SNP sites was identified in V. parahaemolyticus...

The development of the foregut structure and the digestive function of the decapods Litopenaeus vannamei, Sesarma rectum and Callichirus major larvae and post larvae were examined. The protozoeal foregut of L. vannamei is simple, lacking a cardiopyloric valve and bearing a rudimentary filter press. In mysis, the filter press is more developed. In the juvenile stage, grooves and a small lateral ...

The Rab protein family belongs to a superfamily of ras-like GTP-binding proteins. Rab proteins regulate many steps of membrane trafficking. In this study, three Rab family members, Rab5B, Rab6A, and Rab7, designated LvRab5B, LvRab6A, and LvRab7, were cloned from Litopenaeus vannamei. The full-length cDNA sequences of LvRab5B, LvRab6A, and LvRab7 were 1383, 873, and 767 nucleotides in length and...
