Studies advance intensive shrimp culture in zero-exchange biofloc raceways

In ongoing trials of greenhouse-enclosed intensive biofloc shrimp culture systems, the objectives of a 2012 study were to evaluate the performance of fast-growth shrimp fed a commercial diet formulated for high-density culture systems, and to further evaluate injector performance in
