Microbiota from Litopenaeus vannamei: digestive tract microbial community of Pacific white shrimp (Litopenaeus vannamei)
Bacteria capable of producing different extracellular enzymes of potential relevance in digestive processes were isolated from the stomach, hepatopancreas and intestine of Pacific white shrimp Litopenaeus vannamei. A total of 64 strains with proteolytic activity were isolated and grouped into 16 clusters based on morphological characteristics: 4 groups were isolated from the intestine; 5 from t...
متن کاملEffect of short-term starvation on hepatopancreas and plasma energy reserves of the Pacific white shrimp (Litopenaeus vannamei)
Crustaceans are forced to fast during molting. Several physiological, metabolic and behavioral changes have been associated with starvation. Although some of these changes have been well studied, knowledge of the dynamics of fuel reserves during the molting process is limited. To understand the effects of short-term hunger stress on energy reserves, intermolt shrimpLitopenaeus vannameiwere star...
متن کاملEffects of dietary mannan oligosaccharide on growth performance, gut morphology and stress tolerance of juvenile Pacific white shrimp, Litopenaeus vannamei.
An 8-week feeding trial was conducted to investigate the effects of dietary mannan oligosaccharide (MOS) on growth performance, gut morphology, and NH(3) stress tolerance of Pacific white shrimp Litopenaeus vannamei. Juvenile Pacific white shrimp (1080 individuals with initial weight of 2.52 ± 0.01 g) were fed either control diet without MOS or one of five dietary MOS (1.0, 2.0, 4.0, 6.0 and 8....
متن کاملShort communication. SNP analyses of the 5HT1R and STAT genes in Pacific white shrimp, Litopenaeus vannamei
Shrimp aquaculture is one of the growing animal industries. Breeding stocks with high disease-resistance and growth rate are of particular interest to shrimp breeders. Association studies are useful to find genetic markers for marker assisted selection of animals. Using six Litopenaeus vannamei individuals from a sample population, four single nucleotide polymorphisms (SNPs) were found in the 5...
متن کاملEffect of probiotic bacteria Bacillus licheniformis and Lactobacillus rhamnosus on growth of the Pacific white shrimp Litopenaeus vannamei
The effects of single and combined use of two different probiotic bacterial species, Bacillus licheniformis and Lactobacillus rhamnosus on growth performance of Pacific white shrimp Litopenaeus vannamei was evaluated. Shrimp were treated with probiotics in entire crop duration with different test diets. Twelve culture ponds were divided into four groups of each three, Control (CP) without probi...
