A simple & effective way to reduce cost in shrimp-farming

1. A simple & effective way
to reduce cost in shrimp-farming

2. • Very high cost of feed
• Increasing cost of human resources
• Import restrictions from China
Rising Production Cost Low Selling Cost
• Low cost export of shrimp to USA from South
American countries like Ecuador, etc.
• Low selling price
• Reducing profit margins

3. Rising Production Cost Low Selling Cost
CAUSING
ENORMOUS PRESSURE OF COST REDUCTION ON
THE AQUACULTURE FARMER,
ESPECIALLY THE SHRIMP FARMER

4. As a farmer, you don’t have control
over the selling price of shrimp
that is largely dependent on
international prices and
decided by processing units
HOWEVER YOU CAN CONTROL THE INPUT COSTS

5. COST OF FEED COST OF SEED COST OF AERATION
THE 3 LARGEST INPUT COSTS FOR A SHRIMP FARM ARE:
Good quality feed and good quality seed cannot be compromised.
However the cost of aeration can be reduced by almost 60%
with AIROXI AERATION PRODUCTS
without compromising on quality of aeration

6. Most large fish and shrimp farms use paddle wheel or
similar surface aeration methods
AirOxi Tubes &
blowers enable
diffused aeration,
that provides very
fine, 1 mm micro
bubbles in water
These bubbles
further breakdown
into even finer
bubbles in salt water
used for shrimp
culture
Surface aerators
spend almost 75%of
their energy in just
moving the water,
rather than aeration
Despite being known
as aerators, in
reality, they are
water movement
devices
COMPARED TO THIS

7. Diffused Aeration increases production efficiency
In fact the floc in the ponds
and nurseries increases the
efficiency of aeration, so
diffused aeration using
blowers and aeration tube
increases in efficiency as the
culture time increases.

8. Comparative performance of AirOxi Products v/s Paddle Aerators
(Comparison based on market feedback from customers)
Parameter AirOxi TM Tube with piping and blower Paddle Aerator
Type of aeration
Fine Bubble Diffusion
(1mm and less)
Mechanical and surface , through droplets (20
mm)
Numbers required per Hectare 250 mtr / 5 HP blower and piping 8 nos x 2 HP each
Total Power required / hectare for average stocking density 5 HP 16 HP
Biomass supported / HP 1000 Kg per HP 350 Kg per HP
Approximate Initial Cost
1.5 to 1.8 lacs
(blower, piping, AirOxi Tube, etc)
2.40 lac
(30,000/- x 8 nos)
DO – Kg / Hour / HP 3.6 Kg / HP / hour 1.2 Kg – 1.4 Kg / HP / hour
Average DO levels observed in similar conditions
Day time – 8.5 to 9.0
Night – 5.0 to 6.0
Day time – 7 to 7.5
Night – 4.0 to 5.0
Time taken for same increase in DO (SOTR - Standard Oxygen
Transfer Rate)
20 minutes 60 minutes
Power Cost (considering industrial power at 7/- per unit) –
operating 20 hours a day, for 3 months use in a season.
For AirOxi tube – we are also considering 1 HP x 4 nos of paddle
aerator for water circulation
47,250/- for Oxygenation
3,780/- for Water movement (2 hours)
Total – 51,030/-
1,51,200/-
Stocking Density possible because of high DO High to very high Low to medium
Noise Levels Very low High
Operate during feeding time Yes No
Moving parts and maintenance Very Low High

9. Comparative performance of AirOxi Products v/s Paddle Aerators
(Comparison based on market feedback from customers)
As per customer feedback, – blower and
Airoxi tube / aeration tube for diffused
aeration is highly efficient and the high
SOTR (Standard Oxygen Transfer Rate)
is almost 3 times that of paddle wheel
aerator.
This makes the SAE (Standard
Aeration Efficiency) very high and
translates into saving of electricity cost
by almost 60%.
And this is after considering that you
use the paddle aerators to move
water – but only 1hour x 4 times a
day.

10. To calculate your aeration requirement
for your shrimp nursery or shrimp farm
use our online aeration calculator at:

TO ENSURE A GOOD BALANCE, USE
THE PADDLE WHEELS ONLY AS WATER
MOVING EQUIPMENT, AND NOT FOR
AERATION.
LET THE BLOWER AND
AERATION TUBES GIVE YOU THE
REQUIRED AERATION
