Real-time, quantitative polymerase chain reaction (qPCR) analysis has become an attractive alternative for quantification of the acute hepatopancreatic necrosis disease (AHPND) pathogen in infected shrimp. The authors developed a qPCR assay to quantify a virulence plasmid harbored by the bacterium that causes AHPND.
An important criterion when studying biofilters is the conversion rate of total ammonia nitrogen (TAN) to nitrate-nitrogen in production water. Although nitrification rates have been based on media surface areas, they do not always reflect the actual nitrification achieved. Volumetric
Liposomes, synthetic microparticles originally developed for the pharmaceutical industry, can be produced for ingestion by rotifers and artemia. A study found that yellowtail larvae fed rotifers enhanced with liposomes containing taurine had improved growth.
The Global Nutrition Report 2014 highlights that nutrition and food security is a concern in all countries, not just low-income ones. Urbanization and rising living standards are key drivers in the ongoing increases in seafood demand and fisheries development.
Peracetic acid products, which have strong anti-microbial effects, can be used as sanitizers to control water quality in aquaculture systems.
In life cycle analysis of aquaculture, there is a danger of the entire array of embodied resources and impacts being assigned to the production facility. Producers have no control over the inefficiencies or impacts associated with feed production, but can
The bacterium Flavobacterium columnare and parasite Ichthyophthirius multifiliis (Ich) are common pathogens that can cause heavy economic losses for fish culture. The authors conducted a study to evaluate the susceptibility of hybrid tilapia to F. columnare, including fish mortality and
A preliminary study investigated the effects of diet on the meat quality and shell color of Pacific abalone. A test diet and a commercial abalone feed resulted in lower meat protein content compared to that achieved with a diet of
Shrimp culture in coastal Bangladesh is threatened by climate change variables that include flooding, cyclones, drought, salinity changes and rising sea levels. Holistic planning can help reduce the impacts.
Although today’s soybeans offer many benefits, farmers can also plant alternatives, sometimes on the same farms that raise genetically modified beans. Organic beans meet specific market demands, and a conventionally bred non-GMO bean has been developed for use in aquafeeds
