ABSTRACT: The effect of methods to remove protein content on the properties glucosamine hydrochloride from shells white leg shrimp (Litopenaeus vannamei) and black tiger (Penaeus monodon) was investigated. Chitin obtained by demineralization in 6% HCl for 12h, deproteinization two different (first group soaked 8% NaOH 36h second treated Alcalase enzyme at concentration 0.2% 36h). Two samples we...

La oxitetraciclina (OTC) es un antibiótico frecuentemente utilizado en el control de enfermedades provocadas por Vibrio granjas cultivo camarón Penaeus vannamei. Se evaluó la degradación OTC muestras sedimento y agua marina (2:98 p/v), con como estándar adicionada alimento para camarón, ambos casos a 10 µgmL-1. Los ensayos tuvieron una duración 40 días, se evaluaron factores abióticos exposició...

The effect of Vibrio parahaemolyticus IPNGS16 on the bacterial profile gut Penaeus vannamei was assessed by 16S metagenomic analysis. V3 hypervariable region rDNA amplified PCR. Sequencing reads were generated using 2×150 (300 cycles) for base-read length chemistry Illumina MiniSeq platform. web-based Shaman and MicrobiomeAnalyst platforms used to analyze sequences. phyla Proteobacteria, Bacter...

The replacement of fishmeal with plant protein sources has been studied in Penaeus vannamei. However, it only from the point view replacement, forgetting integral role that plays nutrition shrimp. This study aimed to determine if a supplement dietary phosphorus can sustain by blend feedstuffs, betaine and tauren as attractants still supporting homeostasis, growth, digestive enzymes, lipid-solub...

Pacific white shrimp (Penaeus vannamei or Litopenaeus vannamei) is native to South America, high economic value, and widely cultivated in the world Vietnam. Over last two decades, viral diseases have seriously threatened aquaculture industry. Among diseases, spot syndrome virus (WSSV) most important pathogens of farming. WSSV causes a cumulative mortality can reach 100% within 3–10 days. Genome...

Abstract This review summarises the current knowledge of mineral nutrition for penaeid shrimp. It investigates how aquatic environment and lifecycle shrimp affect requirements role that minerals play in health. Methods supplying via either water or to feed, novel ways supplementing within are discussed. The individual summarised with recommendations minimum levels dietary inclusion semi‐intensi...

Penaeid shrimp aquaculture is impacted by various diseases. However, most published studies on physiological responses to pathogens have focused the changes in one or two tissues of infected a single pathogen, effects infecting tissue. There has been limited systematic examination similarities and differences immune multiple under pathogen infection. Here, transcriptomic three (gill, hepatopanc...
