Tag Litopenaeus vannamei

Research from experimental trials demonstrate that dietary potassium diformate improves survival, growth and productivity in Pacific white shrimp (Litopenaeus vannamei), including in the presence of the Gram-negative, pathogenic bacterium V. harveyi. 

El cultivo del camarón tierra adentro tiene numerosas ventajas – mejora la bioseguridad, el costo más bajo de la tierra, y reduce los conflictos con otros usuarios de recursos comunes como la tierra y el agua – y seguirá expandiéndose hacia nuevas áreas. 

Shrimp aquafeeds – live, fresh or formulated – should not be an entry point of potential pathogens to the shrimp and/or to their culture systems. 

Inland shrimp culture has numerous advantages – improved biosecurity, lower cost of land and reduced conflicts with other users of common resources like land and water – and will continue to expand into new areas. 

A study compared the bioavailability of crude protein and lipid from biofloc meals generated with an activated sludge system using two water sources: wastewater from shrimp experimental culture (BFL-W) and, artificially, using clean seawater (BFL-C). 

Accurate PCR testing of shrimp seedstock assures shrimp farmers that their seedstock is clean of major diseases. Ring tests verify that labs conducting PCR testing are obtaining correct, reliable and reproducible results when testing for specific shrimp diseases. 

Este estudio evaluó cinco dietas formuladas con niveles crecientes de metionina (Met) y Met + cisteína (Cys) y sus efectos sobre el crecimiento de juveniles de camarones blancos del Pacífico sembrados a 50, 75 o 100 animales/m2 en un sistema de agua verde. 

Shrimp production systems and their feed management must be considered together. It requires an understanding of biological aspects of the targeted species and age, of production system used, of chemical and biological processes that control water and bottom quality and continuous system monitoring and feedback to provide appropriate and timely inputs and adjustments. 

Studies demonstrate that hydrolyzed soy protein can be well digested and utilized by Pacific white shrimp, and that digestibility is improved through a bioprocess with the bacterium Lactobacillus spp. 

El uso de la tecnología de biofloc (BFT) está aumentando en la producción comercial de varias especies acuáticas importantes, ya que puede aumentar la producción y la eficiencia y minimizar los posibles impactos de los efluentes. Este estudio mostró que los sistemas BFT sin recambio de agua y suplementados con melaza o dextrosa como fuente de carbono producen un rendimiento y calidad de agua adecuados durante la fase de criadero de L. vannamei. 

The use of biofloc technology (BFT) is increasing in the commercial production of several important aquatic species, as it can increase production and efficiency and minimize the potential impacts of effluents. This study showed that BFT systems without water exchange and supplemented with molasses or dextrose as a carbon source yield adequate production and water quality during the hatchery phase of L. vannamei. 

本文介绍了新兴对虾微孢子虫病（EHP）的组织学特征，使用了对患病对虾肝胰腺组织，排泄物，养殖水缸中水样和一些卤虫生物量的PCR化验分析的方法来检测到EHP的存在。(Editor's note: This article was originally published on the Advocate in English on April 15, 2016.) 

The stable isotopes technique with δ13C and δ15N can be used to determine the relevance of different food sources to shrimp feeding during the pre-nursery phase of Litopenaeus vannamei culture. During this trial, different types of commercial feed, microalgae, Artemia sp. nauplii and bioflocs were used as food sources. 

The Brazilian aquaculture industry has been growing steadily during the last two decades. Despite facing a number of challenges it is looking at continued growth and a larger role in the export markets. 

Live markets represent a promising niche in regions where locally raised seafood cannot compete with inexpensive imports. Study results suggested regional shrimp producers could effectively reach premium markets by shipping using waterless methods.
