micro/nano bubble for aquaculture_01

When you think about the aquaculture, you can easily understand micro/nano bubbles are good for the objects. Most of the aquaculture farmers use air blowers/stones to provide oxygen to them. If it provides enough oxygen, air blowers/stones are not so bad, but sometimes lack according to aquaculture objects growth. Specifically the later part of the aquaculture, the products grow big and consume oxygen well, then DO (dissolved oxygen) decrease. When DO decrease, anaerobic bacteria (Vibrio is the one) activate and all the objects may die at once. This often happens in aquaculture farm here and there.

Using the micro/nano bubble generator at the aquaculture pond, the benefits are follows.

1.     It can keep DO high level. (ideally more than 5.0mg/L)

Micro/nano bubbles stay and float in the water much longer than the mm level bubbles. Therefore even if the switch of Micro/nano bubbles generator is off for an hour, DO of micro/nano bubble water keep high level, but DO of air blower/stone decrease soon. 

2.     It can promote the consumption of the breed.

If the fish eat well, the leftovers become less and grow well. As a result, the food conversion ratio (feed/harvest) goes down.

3.     It can facilitate the speed of the growth.

4.     It suppress the occurrence of anaerobic bacteria.

5.     It can reduce cost.
