Yes. Fish in cages is also very easy to feed. It feeds on common fish feeds including pellets. These are dropped on the waters over the cases and fish comes up and scoop it. The advantage is that the feeding is well controlled so there is no wastage of feeds. Because of the easy and targeted feeding, the fish grow faster.
The farmer’s production is predictable, which is not so with fishing in the wild. You may go out with 100 nets and you come back with two pieces of fish. But if you have your cage and you have looked after these fish very well, you can predict the production, and even the money that you can get from it.
