The aim of this study was to evaluate the sensory quality Pacific white shrimp (L. vannamei) fed diets in which fish meal replaced by soy protein concentrate. Four were evaluated, with different levels replacement (33%, 66% and 100%) In analysis, 50 tasters evaluated using ordering preference test acceptability shrimp. inclusion vegetable source diet showed no difference discriminatory did not ...

Experimental studies were conducted by injecting or feeding white spot syndrome virus (WSSV) derived from infected shrimp, Penaeus monodon (Fabricius), collected from the south-east coast of India, to five species of shrimp, two species of freshwater prawns, four species of crabs and three species of lobsters. All species examined were susceptible to the virus. Experimental infections in the sh...

Presumptive systemic streptococcal infections were detected histologically in farmed Litopenaeus vannamei juveniles submitted from a Latin American country and the bacteria isolated. Characterization work demonstrated that the Gram-positive cocci form chains, grow aerobically and anaerobically, are oxidase- and catalase-negative, non-hemolytic, non-motile, Lancefield Group B positive and PCR po...

Accompanying acute hepatopancreatic necrosis disease (AHPND) in cultivated Asian shrimp has been an increasing prevalence of vermiform, gregarine-like bodies within the shrimp hepatopancreas (HP) and midgut. In high quantity they result in white fecal strings and a phenomenon called white feces syndrome (WFS). Light microscopy (LM) of squash mounts and stained smears from fresh HP tissue reveal...

The banded coral shrimp, Stenopus hispidus (Crustacea: Decapoda: Stenopodidea) is a popular marine ornamental species with a circumtropical distribution. The planktonic larval stage lasts ∼120-253 days, indicating considerable dispersal potential, but few studies have investigated genetic connectivity on a global scale in marine invertebrates. To resolve patterns of divergence and phylogeograph...

Vibrio harveyi is a Gram-negative bacterium found in tropical and temperate marine environments as a free-living organism or in association with aquatic animals. We report the first sequenced genome of a Vibrio harveyi strain, CAIM 1792, the etiologic agent of the "bright red" syndrome of the Pacific white shrimp Litopenaeus vannamei.

White spot syndrome virus is a major pathogen of shrimp, causing economic loss to the aquaculture industry. For the first time, a complete de novo genome of an Indian isolate of this virus has been deciphered using Illumina and Nanopore sequencing technologies. The genome has 280,591 bp with 442 predicted coding genes.

A yeast culture feed supplement (Diamond V XP Yeast CultureR, Diamond V Mills, Cedar Rapids, Iowa [IA]) was assessed for its impact on disease resistance in the Pacific white shrimp, Litopenaeus vannamei. Animals were fed a standard shrimp pellet diet supplemented with 0% (control with 1% grain carrier), 0.5% (with 0.5% carrier), or 1.0% XP daily for 4 weeks. To assess resistance to bacterial d...

Aflatoxins (AFs) are one of the most important mycotoxins due to their common occurrence in feedstuffs and feeds that pose a serious threat to humans and animals. Although many outbreaks of acute and chronic diseases have been attributed to consumption of aflatoxin-contaminated foods, the most significant effect of aflatoxin is hepatotoxicity in farm animals, especially aflatoxicosis in shrimps...
