A recent study reported that the expression of six
selected genes (prophenoloxidase [ProPO1 and ProPO2], serine

masquerade-like serine protease [mas] and Rat-sarcoma-related
nuclear protein), directly and indirectly related to the shrimp immune
response, were significantly upregulated in biofloc-grown
shrimp
