Proactive measures address hepatopancreas problems in HOSO shrimp
A shrimp's ruptured or discolored hepatopancreas is from a combination of factors involving nutrition, stress or toxins at various production chain levels.

Shrimp processing byproducts find many uses
Shrimp processing byproducts are constructively used in shrimp or fish feeds, livestock feeds and plant fertilizer. Chitin from shrimp exoskeletons is used in bandages and varied cosmetic products.

Genetics contribute to profitable shrimp production
Genetics is an important factor in shrimp farming. Improvements in disease resistance and robustness can be achieved with within-family selection, shorter generation intervals and marker-assisted selection.

Shrimp copyright: Inbreeding strategies effective against copying of genetically improved shrimp
Shrimp breeders often protect their genetic investment by selling broodstock that will accumulate increasing levels of inbreeding in successive generations.

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.

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.
