The product is made from FRP due to its unique properties like light in weight, low water absorption, free from corrosion, easy to fabricate and repair. It reduces feed loss (10-15%) and man-hour involvement for feeding. The growth rate of fish is 10-15% higher in demand feeding cisterns than the hand feeding tanks as the fish themselves decide when and what amount of feed they want to consume. This helps to avoid organic pollution in the rearing ponds by delivering demanded quantity of feed into it. The demand fish feeder increases the feed consumption of fish by making it available to them continuously.
