Biofloc system with synbiotic supplementation improves Penaeus vannamei immunity against AHPND.

ABSTRACT: Mass mortality due to disease emergence has resulted in enormous losses in shrimp production. One of the deadliest shrimp pathogens is the disease-causing Vibrio parahaemolyticus (VP_AHPND), which induces acute hepatopancreatic necrosis and has recently become resistant to various classes of antibiotics. Biofloc systems and synbiotic feed supplementation are potential alternative strategies for overcoming this problem. In this study, a biofloc system was generated by inoculating the probiotic Halomonas alkaliphila, a consortium of nitrifying bacteria, and the microalgae Chaetoceros calcitrans with molasses at a C/N ratio of 15. The synbiotic-supplemented feed contained 0.375% (w/w) of prebiotic red seaweed Kappaphycus alvarezii powder, 0.125% (w/w) Spirulina sp., and freeze-dried
