which of the following combinations are most suitable for composite fish culture?

• Surface feeders and bottom feeders
• surface feeders middle zone feeders and bottom feeders
• middle zone feeders and bottom feeders
• surface feeders only
• middle zone feeders only
• bottom feeders only

Your friend Hamsa is correct!

• Composite fish culture is the practice of growing 5 to 6 species of fish in the same Fish tank. It includes the use of surface feeders, middle zone feeder and bottom Feeder.
•  Fishes with different food habitats are chosen so that they do not compete for food among themselves.
•  Also, this ensures a complete utilization of food resources in the pond. 
• As a result, the survival rate of fish increases and their yield also increases.
