A super-intensive, commercial-scale RAS trial with Pacific white shrimp at Oceanic Institute achieved record production at a low cost and with low stocking densities.
Cavitation occurs in a centrifugal pump when the effects of low internal water pressure lead to impeller damage. Proper design and installation of pumping systems can help.
Recirculating systems and health management schemes should be designed concurrently to maximize their effectiveness.
A super-intensive RAS grow-out trial produced 5.7 kg of shrimp per square meter in 14 weeks using minimal water volume and only 0.34 percent daily water exchange.
Microbes facilitate high-intensity recirculating aquaculture systems. Research indicates that the microbial community changes throughout grow-out.
RAS technology can be applied to shrimp culture. The author developed a small-scale prototype RAS for shrimp larval culture that successfully reared monodon nauplii to PL15.
In a study, a radial-flow settler provided approximately twice the TSS removal efficiency of a comparable swirl separator.
High-density RAS polyculture of channel catfish and tilapia in tanks or raceways has several advantages over traditional pond culture.
Phosphorus is one of the most scrutinized nutrients discharged by aquaculture systems, due to its potential eutrifying impact on receiving bodies of water.
