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. 

Although the characteristics of shrimp postlarvae have changed over time, the standard method used to identify their size has not. Usually, the “size” of postlarvae is considered their chronological age after completing metamorphosis. 

Polymerase chain reaction (PCR) testing demonstrated that Penaeus monodon offspring derived from founder shrimp collected from the Indo-Pacific region had genomic infectious hypodermal and hematopoietic necrosis-related DNA sequences that reacted with OIE-listed IHHN virus diagnostic primers. 

The University of Arizona Aquaculture Pathology Laboratory identifies a unique strain of Vibrio bacteria as the causative agent for EMS/AHPNS. 

To meet demand and maintain the sustainability of the shrimp aquaculture industry, commercial synthetic artemia has been developed for use as a bio-secure replacement for live artemia in larviculture. 

Since Taura syndrome virus was in the Americas when yellow head virus become pandemic in Asia, it is possible TSV prevented shrimp in the Western Hemisphere from infection by materials from Asia containing YHV. To test this idea, the authors evaluated the viral interactions in shrimp preinfected with TSV and then challenged with YHV. 

A five-year project was undertaken in Brunei Darussalam to develop advanced technology for the production of large black tiger shrimp. A combination of technologies has enabled efficient production of large-sized black tiger shrimp, which could lead to a resurgence of this species in Asia. 

For a five-year project undertaken in Brunei Darussalam to develop advanced technology for production of large black tiger shrimp, a comprehensive disease diagnostic laboratory was developed to enable detection of known and emerging shrimp pathogens by molecular and histological methods. 

Specific pathogen-free offspring developed from founder populations of P. monodon collected from Brunei coastal waters were introduced into a biosecure breeding program, where they have been reared to the fifth generation using family-based selection for reproduction and growth.
