Aquacultural importance of the integumental pore pattern in postlarval whiteleg shrimp Litopenaeus vannamei (Decapoda: Penaeidae).
نویسنده
چکیده
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 commercially significant group. Important factors to be defined on a geographic population or group basis include differences in domesticity (eg resistance to pathological agents); food conversion indexes and food preferences; growth indices; tolerance to stress of various origins and other attributes useful in aquaculture. This consideration is valid not only for L. vannamei but also for any other shrimp species that has been the object of artificial redistribution.

Whiteleg shrimp, Litopenaeus vannamei is one of the most commercially farmed species worldwide because of its fast growth, good survival rate at high farming densities, and osmoregulatory capacity, which makes it an excellent candidate for cultures at different salinities. The knowledge of shrimp nutritional requirements is critical in the formulation of diets to allow optimal growth at differe...

Genetic variation within and between fifteen closed broodstock lines of the Pacific white shrimp Litopenaeus vannamei, reared at different hatcheries in the Brazilian coast, was assessed by RAPD analysis. Fifty two polymorphic loci were identified when a set of five decamer primers was used in PCR. The genetic diversity analysis within lines evidenced genetic variation loss probably related to ...

We present a new transcriptome assembly of the Pacific whiteleg shrimp (Litopenaeus vannamei), the species most farmed for human consumption. Its functional annotation, a substantial improvement over previous ones, is provided freely. RNA-Seq with Illumina HiSeq technology was used to analyze samples extracted from shrimp abdominal muscle, hepatopancreas, gills and pleopods. We used the Trinity...
متن کاملAnalysis of multiple tissue-specific cDNA libraries from the Pacific whiteleg shrimp, Litopenaeus vannamei.
Multiple small-scale transcriptome studies have been undertaken for various members of the Penaeidae. Penaeid shrimp are important both as members of diverse ecosystems around the world and for their importance as commercial commodities. Of the many shrimps, the most important from this family is the Pacific whiteleg shrimp, Litopenaeus vannamei, as it is the primary shrimp used in worldwide aq...
