Aquaculture refers to the rearing of fish, oysters, shrimps or seaweed for nutrition in a controlled environment like pond, tank or part of a lake.
People resorted to aquaculture when the need for high quality protein rose continuously but there was not enough fish from the sea.
One major advantage of aquaculture when compared to fishing from the sea is that tidal and wind variations can't hamper the amount of produce.
If aquaculture is being performed in tanks, the waste produced by these fishes will deposit at the bottom of the tanks which can be used as a good manure.
To increase the amount of omega 3 fatty acids from the reared fish, micro algae and other small fishes are fed to them.
The amount of dissolved oxygen depletes very quickly from tanks, so a pump maybe required in some cases to pump air into water.
