What is chem-free shrimp?
The use of phosphates to protect shrimp moisture has been questioned due to abuses. The alternative demand for chem-free shrimp can involve similar abuses and deception.

P.L. size, source strong early measures of shrimp grow-out performance
Artificial diets are used to replace live artemia at commercial shrimp hatcheries, but complete replacement remains a challenge for strong grow-out results.

Kona-line SPF shrimp, Vibrio penaeicida candidates for bacterial challenge model
Juvenile SPF Kona-line shrimp were injected with V. penaeicida, causing significant disease, but certain bacterial concentrations allow survival long enough for additional testing.

Selective breeding for shrimp: Adapting to multiple pathogens, intensive culture
Through selective breeding, genetic improvement programs can develop shrimp lines that exhibit commercially desirable traits like fast growth, disease resistance and overall hardiness.

Tracing origins, diversity loss in captive shrimp
Genetic diversity loss occurs in any stock of shrimp allowed to inbreed at random. Intentional inbreeding for performance traits accelerates rate of loss.

New nursery diet for shrimp performs well at super-high stocking densities
A shrimp diet developed in trials is the first dry nursery diet shown to ensure good performance at stocking densities up to 45,000 per square meter.

SPF-defined pathogen-free status of shrimp limited
Specific pathogen-free status depends on the presence or absence of specific pathogens. This status depends on the level of biosecurity for the shrimp.

Shrimp farming in Italy: Status and perspectives
Shrimp farming in Italy has been largely based on the introduced species Kuruma shrimp (M. japonicus), providing an alternative source to imports.

Phosphates and shrimp
Commercial experience and research have demonstrated that phosphates can enhance sensory quality and increase consumer appeal for shrimp. Through over 10 years of research with shrimp from around the world, the Aquatic Food Products Lab at the University of Florida in Gainesville, Florida, USA has shown that consumers prefer shrimp properly treated with phosphates. However, processors must have a clear understanding that misuse of these ingredients can result in poor appearance, poor texture, and consumer rejection.

Role of hormones in shrimp growth, reproduction
In most decapod crustaceans the physiological processes of metamorphosis, molting and reproduction are inextricably linked and controlled by hormones.
