In this research, we illustrate that the application of biofloc
technology for Pacific white shrimp culture significantly affects the
shrimp immune response, a currently underexplored feature of
bioflocs, and may increase the robustness of shrimp to resist
infection. These effects seem to be independent of the type of
carbon source used to grow the bioflocs.
Each type of bioflocs grown on a different carbon source
(molasses, tapioca, tapioca by-product, rice bran) was adequate in
maintaining the overall water quality parameters in a normal range
for shrimp growth. The lower level of dissolved inorganic nitrogen
generally observed in the tanks with biofloc treatment as compared
to the control with regular water replacement confirmed previous
reports regarding the effect of BFT application on water quality in
shrimp culture. Avnimelech [6] pointed out different effects of
