Vannamei shrimp culture ponds in Chantaburi, Thailand
Puddle wheels or combined aeration system with blowers and
air stones has been adopted widely in the shrimp culture
ponds. However, the capacity of these devices for dissolving
oxygen gas to the water is fairly limited. Consequently, DO of
the water of the ponds often falls to unhealthy levels for rearing
shrimp, in particular, in the llater half of the culturing period.
DO changes of the water in the shrimp culture pond
DO of the water tends to increase above saturation levels by
photosynthesis of phytoplankton during daytime, while the
phytoplankton consumes DO of the water for respiration during
nighttime. As the feed consumption in the pond increases
following the growth of reared shrimp, the decrease of DO of
the water during the nighttime tends to become severer.
eco-Bubble aeration system for shrimp culture can compensate the insufficient DO supply to the water of the shrimp culture ponds with its extremely high capacity for dissolving oxygen gas to the water.''
