Genetic improvement is the single most important driver of improvement in agriculture. No other area of production such as nutrition, hatchery management, or farm management can yield the consistent annual improvements that are possible through genetic selection.

Animal health

On the other hand, the most critical limiting factor in shrimp farming is disease. For this reason, Kona Bay begins with emphasis on animal health. In addition to a Ph.D pathologist on staff, Kona Bay enlists the diagnostic services of an OIE reference laboratory -- the Aquatic Pathology Laboratory of the University of Arizona, USA.

Specific Pathogen Free

Kona Bay broodstock are certified specific pathogen free (SPF), which means they are free of the following list of specific pathogens:

A rigorous surveillance program continuously monitors the health status of stocks at various life stages.

SPF status assures maximum performance and minimum risk of disease introduction and transmission.


In order to establish SPF status, any prospective new genetic lines are introduced into the Kona Bay nucleus breeding center only after rigorous primary and secondary quarantine protocols defined by OIE and verified by the Hawaii Department of Agriculture. Stocks are maintained and propagated under the strictest biosecurity conditions.

Kona Bay facilities are uniquely designed for this purpose. They are the only shrimp farming facilities on the island of Kauai, which is separated from other Hawaiian islands by at least 200 km of deep ocean. The seawater supply is naturally filtered from deep wells and is free of pathogens. Strict protocols control the movement of personnel, equipment, and supplies.

Selective Breeding

To maximize genetic gain with minimal inbreeding, selection is conducted both among and within families.

Kona Bay broodstock are selected for a balance of traits to assure excellent performance under a variety of conditions at the hatchery and farm.

Genetic markers

Single Nucleotide Polymorphism (SNP) markers are used both for pedigree and trait identification.

Farm Trials

Tank-based growout trials within a nucleus breeding facility may not be an accurate reflection of conditions at commercial farms. It is essential for breeding facilities to conduct growout trials under commercial conditions. For this reason, Kona Bay stocks are tested under a variety of commercial farm conditions:
