Infectious diseases are a major cause to the devastating economic loss in the finfish and shrimp aquaculture operations. An effective strategy against infectious diseases is to enhance the host immunity against the pathogens. The present invention provides a series of nuclear acid immune stimulants for aquacultured finfish and shrimp. These compounds can be applied to enhance the innate and adaptive immunity. These compounds alone can promote the functionality of innate immune cells in fish and shrimp. For fish, these compounds can also be used as adjuvant in various forms of anti-viral vaccines to promote the efficacy of the vaccines. In addition, these immune stimulants can be delivered into the animals via the route of injection, or ingestion as feed additive.
