PVC Frame Pools For Fish Farming

Does aeration is necessary for the tanks?please mention what medicines to apply to the water for set up a new tank? Whether fishes such as pearlspot &grass carp used as mixed cropping? Whether rain fall effects the growth of fishes?

Open tanks are suitable for fish farming. No medicine required for setting up new tank. Just apply some natural fertilizers, such as cow dung. You can raise both pearlspot & grass carp in the same tank. And as far as we know, rain fall doesn’t effect the growth of fishes. Thank you!
