Most required for today's shrimp culture is Aero-Tube. These tubes are manufactured by Colorite Plastics of USA. Tubes are available to the farmers along with knowhow .This tube saves lots of energy and thus cost of production for the farmer for shrimp culture comes down by 35% in electricity alone. Aero-Tubeare used in different shapes of grids.
Geekay hatcheries are the professionals to introduce this tube in India after lots of research being done. These tubes are now being used not only in Andhra Pradesh but also in Kerala Tamilnadu Gujarat and Goa. It is expected by 2013 end there is going to be a transformation to aero tubes from paddle segment.
On introduction of Aero-Tube the cost saving to farmer is shown below

RECOMENDATION ( for one hector)
We should use both
Without using tubes & only aerators
Ist month
blower 3 hp & 140 rings +4 hp aerators 7 hp
Ist month 8 to 10 hp aerators
2nd month
,, & ,, 8hp 11 hp
2nd month
18 hp to 20 hp
3rd month
6 & 300, 10 - 16 hp
3rd month
26 hp
Saving - We Should Use Both
1st month
10 HP - 7 HP = 3 HP (Saving)
2nd month
20 HO-11HP = 9 HP (Saving)
3rd month
26 HP - 16 HP = 10 HP (Saving)
WE CAN GET BACK THE COST OF AERO-TUBE AND BLOWER IN THE FIRST HARVEST ITSELF
