Colombian aquaculture production and exports have grown significantly during the last two years, due to a large degree to the efforts of the industry and the producers’ guild, but FEDEACUA has had an instrumental role supporting producers to achieve various industry international certification standards. 

The explosive growth of shrimp farming has long been associated with mangrove deforestation in Southeast Asia. A silvofishery method of producing the popular seafood is protecting the fragile ecosystems in Vietnam. A hungry marketplace is reaping the rewards. 

This study evaluated the susceptibility to IHHNV in three different shrimp batches by measuring infectivity titers. Each batch showed a different infectivity titer, therefore, each batch had a specific susceptibility to IHHNV. 

A novel blend of organic acids (OAB) microencapsulated in a lipid matrix and supplemented in the diets of Litopenaeus vannamei enhanced their growth, phosphorus utilization, resistance to Vibrio harveyi and immunity. This may have implications as an eco-friendly prophylactic strategy. 

In previewing the SeaWeb Seafood Summit, the Advocate examines human rights in the supply chain and the people who advance solutions in rooting out worker abuses. In part one of a three-part series, Environmental Justice Foundation co-founder Steve Trent talks about linking environmental security with human rights. 

Silencing genes in white spot syndrome virus (WSSV) with critical roles in replication could provide a strong antiviral effect and thus reduce shrimp mortality. The authors therefore established a study to evaluate the antiviral efficacy of double-stranded (ds)RNA against non-structural WSSV genes. 

David Little, professor at the University of Stirling in Scotland, tells the Advocate about the rapid evolution of the aquaculture industry in Southeast Asia — where he made his home for many years — and discusses the role of academia in ushering in new eras of innovation. 

The GOAL 2015 Shrimp Production Survey showed that global farmed shrimp production is rebounding from the decrease seen from 2011 to 2013 due to diseases, and is headed to an all-time high of around 4.8 million metric tons in 2017, barring any new crises. 

Phytoplanktonic organisms, or microalgae, are very abundant in aquaculture ponds and have critical roles in these ecosystems, significantly influencing overall pond ecology and water quality. Proper management of phytoplankton populations is essential for successful aquaculture pond production. 

By raising shrimp in a closed building, producers can increase biosecurity, produce shrimp more consistently, grow shrimp year-round and locate production centers near markets. Chefs and consumers were very accepting of whole fresh shrimp, offered at a farmers market, that was farmed indoors in Kentucky. 

James Anderson delivered a data-rich survey on global shrimp and finfish production volumes for the Global Aquaculture Alliance at its GOAL conference in October. See the full video of his presentation. 

Feed plants deal with varied raw materials, formulations and feeds for different animals, which can lead to quality issues and nutrient variations. Near-infrared spectroscopy (NIRS) has been successfully applied in Brazil to ensure feed quality standards at the farm level. 

The digestive systems of shrimp are main entry points for bacterial and viral pathogens, and unfavorable microflora. Natural feed additives that combine different actions have proven effective in improving survival where shrimp are exposed to bacterial pathogens. 

A study confirmed the utility for improved polymerase chain reaction (PCR) detection of the Vibrio bacteria that cause acute hepatopancreatic necrosis disease (AHPND) in asymptomatic shrimp by permitting the shrimp to expire and decompose for several hours prior to preservation and PCR processing. 

Although relatively expensive, mechanical aeration increases production. Asian-style paddlewheel aerators are widely used but are inefficient. Testing has led to more efficient designs that are now widely used in U.S. catfish and shrimp ponds.
