Tilapia culture has intensified in the last
few years. However, there are thousands of
hectares of ponds operating in semi-intensive
systems with low productivity. The use
of the bottom of these ponds to produce
freshwater prawn in polyculture may increase
produced biomass at very low cost,
thus increasing profits. In addition, polyculture
systems rationally use the energy
available in the system. Food residues and
tilapia feces are consumed by the prawns
and transformed into valuable biomass that
reduces environmental impact.
