The effects of nanobubble on the growth environment,such as dissolved oxygen(DO)and total virus-bacteria,and growth performance,such as growth,feed conversion ratio(FCR),survival rate(SR),total harvest,and productivity,were investigated in Penaeus vannamei shrimp *** present study was carried out in 50 m2 indoor raceway ponds for 81 days with stocking density being set to 680 shrimp m􀀀3 in two types of treatment:nanobubble and diffuser aerator.A paddlewheel was used to distribute the oxygen saturation levels throughout the *** presence of nanoparticles was detected using a dynamic light scattering method and was reported to be 82.38 nm in size and􀀀26 mV for zeta potential *** was significantly higher under nanobubble *** virus-bacteria and FCR decreased,whereas SR,growth(weight and length),total harvest,and productivity increased with increasing *** SR was reported to reach 95%.The average weight and length of *** were 15.1±1.8 g and 13.1±1.1 cm,*** total harvest and productivity have doubled to 436 kg and 8.7 kg/*** results revealed that nanobubble has managed to maintain DO at the optimal range and affected the shrimp growth significantly(P<0.05).
