Comparing biofloc polyculture and IMTA production of Nile tilapia and Pacific white shrimp

To maximize production of both tilapia and shrimp in biofloc polyculture and IMTA production, the two species should be grown separately.

Stocking density affects super-intensive biofloc nursery shrimp production

The authors performed a study to determine the tolerance of shrimp postlarvae to the crowding effects of high-density stocking in terms of production performance. Postlarvae were stocked in heavily aerated microcosm tanks with biofloc at 1,500; 3,000; 6,000 or 9,000 shrimp/m3. High survival was observed at all densities. Final biomass values increased with higher stocking densities, but there was no significant difference between the 6,000 and 9,000 shrimp/m3 treatments or the 1,500 and 3,000 shrimp/m3 treatments.
