In biofloc production systems, ammonia-oxidizing bacteria process ammonia to nitrite, which provides substrate for nitrite-oxidizing bacteria that process nitrite to relatively non-toxic nitrate.

In response to Taura Syndrome Virus outbreaks, the U.S. Marine Shrimp Farming Program initiated a selective-breeding program to improve resistance in Pacific white shrimp.
In research involving white shrimp siblings raised in ponds in Thailand and in raceways in Hawaii, shrimp growth can be improved after one generation of selection, even with a modest investment.
As economic benefits of selective penaeid shrimp breeding become more compelling, the shrimp industry will invest in breeding programs to produce genetically superior stocks.
A super-intensive, commercial-scale RAS trial with Pacific white shrimp at Oceanic Institute achieved record production at a low cost and with low stocking densities.
Results from two studies at Oceanic Institute indicated that shrimp behavior may compromise growth at super-intensive stocking densities.
