Sir, in composite we culture we use only marine fishes or we can put marine and inland together?

Dear Student.
Please find below the solution to the asked query.

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.

Marine fish will not be able to survive in pond, so we do not use marine fish generally in composite culture.
