Use of this method to detect and quantify IHHNV in penaeid shrimp has already revealed new information regarding levels of infection.

Aerated microbial reuse systems utilize intense aeration and mixing to produce yields of 10 to 30 metric tons per hectare per cycle with little or no water exchange.
An alternative waste treatment is intense microbial processing of wastes to facilitate high yields with little or no water exchange.
Aerated microbial reuse systems recycle nutrients in the form of organic detritus, which consists of aggregates of organic particles coated with a film of bacteria.
The final factor in developing a heterotrophic system is the amount of organic material being fed to a pond, and the carbon per nitrogen balance of that material.
In high-density systems with zero water exchange, pond ecology shifts from an autotrophic, phytoplankton-based microbial community to a heterotrophic, bacterial-based community.
Square-shaped and deep ponds may explain partially why Belize Aquaculture is able to produce a large amount of shrimp on a unit area basis.
A zero-water-exchange strategy to produce shrimp reduces the effluents and sediments that would normally be released to the environment by a typical intensive shrimp farm.
The focus at Belize Aquaculture Ltd. was to use clean animals that perform well at high densities and in waters with high nutrient loads.
