Los cultivos larvales de Litopenaeus vannamei presentan altas mortalidades por la presencia del patógeno Vibrio parahaemolyticus, siendo combatido con antibióticos, lo que genera presión selección y resistencia bacteriana. Por se evaluó el extracto en testas Citrus paradisi para inhibir proliferación V. parahaemolyticus mejorar supervivencia L. vannamei, realizado Pontificia Universidad Católic...

Here, we report the draft genome sequence of an isolate of Vibrio parahaemolyticus, VP14, recovered from the gut of Penaeus vannamei shrimp farmed in southern India. The genome of VP14 comprised 5,224,046 bp with a GC content of 45.3% and contained 5,326 genes, including 4,972 coding sequences.

Protein food modulates the activity of proteases of the midgut gland of Penaeus vannamei. Shrimp fed with food containing 15, 30 and 50% protein exhibited differences in trypsin and chymotrypsin activity and trypsin mRNA levels. Shrimp fed with 30% protein showed higher trypsin and chymotrypsin activities than those fed 15 or 50% protein. An additional paralogue trypsin was observed with electr...

Marine biological invasions have been regarded as one of the major causes of native biodiversity loss, with shipping and aquaculture being the leading contributors for the introductions of alien species in aquatic ecosystems. In the present study, five aquatic alien species (one mollusk, three crustaceans and one fish species) were detected during dives, shore searches and from the fisheries on...

The feasibility of totally replacing the fishmeal component of marine shrimp (Litopenaeus vannamei) diets was examined both in the laboratory setting and during a full–scale commercial trial. Animals were fed either a traditional fishmeal–based diet or one in which complete replacement of fishmeal, on a per protein basis, was manufactured using a yeast–based product, NuPro®. Laboratory studies ...

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.

Structural changes in Midwest agriculture over the past two decades have resulted in a number of empty and unused farm buildings. Farmers therefore have been exploring alternative uses of livestock farm buildings for the production of other cash crops, including aquaculture products. In Indiana, Pacific White shrimp (Litopenaeus vannamei) production has attracted interest, and a number of small...

Vannamei shrimp (Litopenaeus vannamei) is a type of that often cultivated. This study aims to identify ectoparasites and their prevalence in vannamei the village Pantai Gading, Kec. Secanggang Kab. Langkat. research method survey method, where observed ponds are 3 ponds, samples taken as much 5% stocking density biota. Samples were randomly then examined at Laboratory Faculty Agriculture, Unive...

cDNA encoding prophenoloxidase (proPO) of the white shrimp Litopenaeus vannamei was obtained from haemocytes by a reverse-transcription polymerase chain reaction (RT-PCR) and rapid amplification of cDNA using oligonucleotide primers based on the proPO sequence of tiger shrimp Penaeus monodon, freshwater crayfish Pacifastacus leniusculus, green tiger shrimp Penaeus semisulcatus (accession no.: A...

BACKGROUND The Pacific white shrimp, Litopenaeus vannamei, is a worldwide cultured crustacean species with important commercial value. Over the last two decades, Taura syndrome virus (TSV) has seriously threatened the shrimp aquaculture industry in the Western Hemisphere. To better understand the interaction between shrimp immune and TSV, we performed a transcriptome analysis in the hepatopancr...
