Biofloc Vs Ras Pdf

Biofloc technology BT is defined as the use of aggregates of bacteria algae or protozoa held together in a matrix along with particulate organic matter for the purpose of improving water quality waste treatment and disease prevention in intensive aquaculture systems. The results of this study indicate that clear-water RAS may be a more productive option than biofloc systems for indoor marine shrimp production.
