| Summary: | 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. |
