The use of intensive raceway nursery systems to produce juvenile shrimp under biosecure conditions is an important WSSV management tool.
Some lesser-understoood shrimp immune functions may become tools for improved disease control in the future.
Environmental stresses affect the immune response of shrimp in a dose-dependent way, increasing susceptibility to disease.
An experiment with WSSV in Peru produced good survival rates in an area where the virus is established and where other efforts have failed.
A variety of factors – postlarval nutrition, disease treatment and control of microflora – contribute to optimal hatchery operations.
Critical to the success of genetic improvement and the breeding program at OI is the use of specific pathogen free (SPF) shrimp stocks.
