| Summary: | Aquaculture is the fastest-growing animal production sector, and
shrimp production already exceeds that of the capture fishery.
Viruses and bacteria account for the majority of disease losses for
shrimp farmers. Viral pandemics in the mid 1990s and, more
recently, a bacterial pandemic from 2009 to 2015 have led to the
conclusion that future, sustainable shrimp aquaculture will depend
on the development of more efficient, biosecure production facilities
that cultivate specific pathogen-free (SPF) shrimp, genetically
improved for growth and disease tolerance or resistance. Major
requirements for development, maintenance, and use of SPF stocks
in aquaculture are effective pathogen surveillance and disease prevention
methods. When protective measures fail and diseases
occur in production ponds, there are currently only a few approved
and practical therapeutic methods available for use with bacterial
pathogens and none so far for viral pathogens. To improve existing
methods of prevention and therapy and to develop new ones,
research is being carried out on the nature of shrimp–pathogen
interactions. Promising results have been obtained at the laboratory
level for possible applications involving the use of immunostimulants
for “immune priming” or “trained immunity” of RNA
interference and of endogenous viral elements. Some of these
promising new directions are discussed. |
