An in-pond raceway system in Alabama was utilized to supply various niche markets, including Asian grocery store chains that desired fresh live fish, recreational pond stocking businesses, private pond owners and fee fishing operations. In many cases, a higher price
Zero-exchange biofloc systems allow elevated stocking densities and production, but also require more dissolved oxygen and thorough water circulation. A new type of air injector uses only a centrifugal pump to recirculate water while naturally aspirating ambient air.
The authors conducted studies to test the performance of young shrimp postlarvae in systems with different approaches to aeration and water handling. Proactive management through proper feed applications and water quality control were critical elements.
By dividing ponds into smaller, more controllable areas, IPRS can substantially reduce chemical treatment costs, improve treatment delivery and allow new treatments that are cost-prohibitive in traditional pond settings.
Highly controlled tank and raceway systems can help farmers raise postlarval shrimp to larger sizes before stocking in grow-out ponds. Raceways have recently been implemented for EMS management.
A trial in a lined, greenhouse-enclosed raceway evaluated the use of a heterotrophic biofloc system equipped with aeration, supplemental oxygen injection and centralized heating to achieve good shrimp production.
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
Research at the Texas AgriLife Research Mariculture Laboratory is investigating ways to improve the economic viability of super-intensive raceways for shrimp production.
Optical scanning and associated imaging software reduces stress and increases accuracy as compared to traditional techniques for shrimp measurements.
