POTENTIAL USE OF ORGANIC MINERAL AS MINERAL SOURCE FOR DIET OF JUVENILE VANNAMEI SHRIMP, Penaeus vannamei

Taura syndrome virus from Penaeus vannamei shrimp cultured in Korea.

Mass mortality occurred among Penaeus vannamei shrimp cultured in Korea in 2004. In an earlier study, we reported white spot syndrome virus (WSSV) as a causative agent of mass mortality of P. monodon shrimp in Korea (Moon et al. 2003; Dis Aquat Org 53:11-13). However, in the present study, we detected Taura syndrome virus (TSV) from the moribund 2004 P. vannamei shrimp by reverse transcription ...

Probiotics in Larvae and Juvenile Whiteleg Shrimp Litopenaeus vannamei

Using date pits powder as a low-cost carbohydrate ingredient in the diet of whiteleg shrimp Penaeus vannamei

The present study examined the effect of date pits powder as a low-cost and nutritive carbohydrate source compared to wheat, rice and corn meal in the diet of Pacific shrimp. The date pits meal was applied to the diet at the levels of 0 (control group), 5, 10, 15 and 23%, and the growth performance of shrimp was examined in 8 weeks. The results showed that the weight and length gain, specific g...

Penaeus vannamei isotrypsins: purification and characterization.

Three isotrypsins from digestive gland of Penaeus vannamei were purified and characterized by molecular, biochemical and kinetic parameters. Purified isotrypsins A, B, and C are glycoproteins with molecular masses between 30.2 and 32.9 kDa, and, therefore similar to other trypsins. The isoelectric points are anionic and different among the three isotrypsins: pH 3.5 for isotrypsin A, pH 3.0 for ...

Genetic improvement of Pacific white shrimp [Penaeus (Litopenaeus) vannamei]: perspectives for genomic selection

The uses of breeding programs for the Pacific white shrimp [Penaeus (Litopenaeus) vannamei] based on mixed linear models with pedigreed data are described. The application of these classic breeding methods yielded continuous progress of great value to increase the profitability of the shrimp industry in several countries. Recent advances in such areas as genomics in shrimp will allow for the de...
