Oxygen devices are crucial instruments in shrimp aquaculture, including vannamei shrimp farming. The objective of this study is to compare water quality and shrimp growth parameters between two aquaculture ponds, pond A and pond B, utilizing different aeration methods: Pond A uses 12 paddle wheels (macrobubble), while pond B uses a combination of 6 paddle wheels and 6 microbubble devices (macromicrobubble). The research results shows that the dissolved oxygen (DO) levels in pond B are higher (5,96 mg/l) compared to pond A (5,12 mg/l), supporting better shrimp health. Other water quality parameters such as salinity, temperature, pH, and brightness showed no significant differences between the two ponds. Feed usage was higher in pond B, with an average difference of 16,52 kg compared to pond A. The average daily growth rate of shrimp in pond B was higher (0,19 grams) compared to pond A (0.13 grams), with a larger shrimp population in pond B (253.542 shrimp) compared to pond A (238.673 shrimp). The shrimp biomass in pond B reached 1398 kg, greater than Pond A's 1239 kg. The survival rate (SR) of shrimp in pond B was also higher (84.12%) compared to pond A (79,25%). The feed conversion ratio (FCR) at harvest showed better values in pond B (1,46) compared to pond A (2,3). The average body weight (MBW) of shrimp in pond B was greater (6.04 grams) compared to pond A (5.72 grams). These results demonstrate that the use of a macro-microbubble combination is more effective in promoting shrimp growth and health compared to using macrobubble alone. The addition of microbubbles improves shrimp health and growth but cannot be used from the start of cultivation due to the risk of shrimp mortality because the small size of the shrimp, thus requiring use alongside paddlewheels.
