Biosecurity measures in specific pathogen free SPF shrimp hatcheries

Biosecurity measures in specific pathogen free (SPF) shrimp hatcheries 

SPF Penaeus vannamei in Asia resulted in dramatic increases (a tripling) in total shrimp farming production between 2000 and 2009 (Fig. 10.1). 

This rapid expansion of white shrimp production in Asia resulted from widespread availability of High Health PL derived from SPF broodstock. To produce High Health PL requires use of SPF broodstock combined with good biosecurity at the hatchery. If shrimp larvae produced from SPF broodstock are infected with disease during their hatchery phase, the benefits of using SPF shrimp are lost. Thus best use of SPF broodstock in a shrimp hatchery requires special attention to biosecurity to produce true SPF or High Health PL. 

Using hatchery-produced seed was expected to increase the reliabihty of shrimp farming, and shrimp hatcheries were developed in both hemispheres. PL were produced in land-based hatcheries from wild-caught broodstock. These PL were genetically wild animals because their parents
