A simple & effective way to reduce cost in shrimp-farming
•
CURRENT SCENARIO
Rising Production Cost
Very high cost of feed
• Increasing cost of human resources
• Import restrictions from China
Low Selling Cost
• Low cost export of shrimp to USA from South American countries l ike Ecuador, etc.
• Low selling price
• Reducing profit margins
SHRIMP FARMING:
CURRENT SCENARIO
CAUSING
ENORMOUS PRESSURE OF COST REDUCTION ON THE AQUACULTURE FARMER, ESPECIALLY THE SHRIMP FARMER
Rising Production Cost
Low Selling Cost
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
THE 3 LARGEST INPUT COSTS FOR A SHRIMP FARM ARE:
COST OF FEED
COST OF SEED
COST OF AERATION
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
Most large fish and shrimp farms use paddle wheel or similar surface aeration methods
COMPARED TO THIS
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
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
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 culture time increases.

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

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 1 hour x 4 times a day.
TO ENSURE A GOOD BALANCE, USE THE PADDLE WHEELS ONLY AS WATER MOVING EQUIPMENT, AND NOT FOR AERATION.
