Use of microbubble generator on the growth vannamei shrimp culture

The advanced challenges from the vannamei shrimp cultivation nowadays keep on pushing the fisheries industry on improving its productivity, however, with minimum use of water resource and an efficient land. This research aims to discover the growth and survival rate of vannamei shrimp that is cultivated in a circular tarpaulin pond with a microbubble aeration system. This research shows that microbubble can increase the amount of dissolved oxygen (DO) within the tarpaulin pond, in which the value of DO in the system blower is 3.69 Mg/L and 5.05 Mg/L in the microbubble system. The DO value within the tarpaulin pond with the microbubble system also affects the growth and viability of the shrimp, in which the growth of shrimp cultivated in the microbubble tarpaulin pond is greater (10.16 gr) than those cultivated in the blower pond (8.77 gr). Moreover, microbubble is more efficient on the use of shrimp’s feed provided with the smaller FCR value than the blower group. The application of microbubble in the circular tarpaulin pond with a high density of population can increase the amount of dissolved oxygen and therefore support the growth of aerobic bacteria to prevent air quality degradation in consequence to increase the viability of the shrimp.
