True.
Explanation:
It is TRUE that Polyculture is well suited to intensive aquaculture because you have two or more non-competing species in the same system.
This is evident in the fact that Polyculture is a type of agriculture whereby more than one species of plant is cultivated or animals reared simultaneously.
For example, Polyculture in animals may involved paddlefish, tilapia, and bighead carp reared in the same pond. In this case, the paddlefish will feed on crustaceans, while tilapia feed on zooplankton and phytoplankton. Also, bighead carp will feed on zooplankton and big phytoplankton.
