Wants Help with Aeration


I am looking for some suggestion and guidance on aeration equipment for a start-up Penaeus vannamei farm in the state of Odisha on India’s east coast.  I have two ponds, about one-hectare each and a reservoir.  For my first crop, I plan to stock 15 to 20 postlarvae per square meter.  I have looked at the possibility of using Aero-Tubes and want to know if they will help me keep my production costs down.  Do you suggest using Aero-Tubes in conjunction with paddlewheels?  If I stock 150,000 PLs in each pond and use a 3-horsepower (hp) blower, 150 meters of Aero-Tubes and four, 2-hp paddlewheels, would that be enough aeration for both ponds.


I want to keep my investment as low as possible.  If I’m successful with the first crop, I would like to double my stocking density.  How much aeration would I need if I did that?


Right now the ponds are ready with biosecurity in place, and they are being filled with water as I write this letter.
