Question

Intensive fish farming can be done in composite fish culture system. Explain this system.

Answer 1

Composite Fish Culture System:

• Sometimes fish culture is done in combination with rice crops so that fish grow along with paddy in the standing water. Both local & imported varieties of fish can be used in such systems.
• In such a system, 5/6 species of fish are selected & reared in a single fish pond. The species are selected on the basis of their feeding habits and they should not compete for food & should not kill each other in the pond.

Advantages:-

• Fish do not compete for food
• Food available in different zones is utilized
• Carps consume only aquatic weeds
• Very high yield is obtained

Disadvantages:-

• Many fish breed only in the rainy season so hormonal stimulation has to be given.
• Good quality seeds are not available.
