A study was conducted to investigate the effects of potassium diformate (K-diformate) supplementation in two protein levels on growth, food conversion and survival juvenile white shrimp, litoppenaeusvannamei.Two dietary levels, 41% protein(CP41) 37% protein(CP37) formulated supplemented graded K-diformate 0%, 0.1%, 0.2%, 0.4%, 0.8%, 1.4% 2.0%.Post larvae shrimp (Litopenaeusvannamei) initial mea...

The present study evaluated the susceptibility of three different batches of whiteleg shrimp Litopenaeusvannamei from Mexico to an inoculum of infectious hypodermal and haematopoietic necrosis virus (IHHNV). Each of the three shrimp batches came from a different hatchery. Because of their origin, it was possible that the genetic makeup of these batches was different among each other. The three ...

Growth is a priority trait from the point of view of genetic improvement. Molecular markers linked to quantitative trait loci (QTL) have been regarded as useful for marker-assisted selection (MAS) in complex traits as growth. Using an intermediate F2 cross of slow and fast growth parents, a genetic linkage map of Pacific whiteleg shrimp, Litopenaeusvannamei, based on amplified fragment length p...

Com este estudo, objetivaram-se isolar e identificar leveduras presentes na microbiota intestinal de Litopenaeusvannamei cultivados em estuário tropical testar in vitro a capacidade probiótica adsorvente aflatoxina B1(AFB1)por cepas Saccharomyces cerevisiae isoladas. Foram adquiridos 40 camarões da espécie L. vannamei, fizeram-se o isolamento identificação intestinais por sequenciamento molecul...

Inhibitors of apoptosis (IAPs) play important roles in apoptosis and NF-κB activation. In this study, we cloned and characterized three IAPs (LvIAP1-3) from the Pacific white shrimp, Litopenaeusvannamei. LvIAP1-3 proteins shared signature domains and exhibited significant similarities with other IAP family proteins. The tissue distributions of LvIAP1-3 were studied. The expression of LvIAP1-3 w...

Isolation of autochthonous bacteria from marine sources as a potential probiont in biocontroling against pathogenic Vibrio species in the shrimp culture industry was the aim of current research. A total of 198 bacterial strains were isolated from pond water, sediment, hepatopancreas and gut samples of shrimps after culturing the samples on Tryptic Soy Agar and incubated at 30 °C for 24-48 h. Th...
