Recirculating Aquaculture Tank Production Systems: Integrating Fish and Plant Culture

Recirculating aquaculture systems are designed to raise large quantities of fish in relatively small volumes of water by treating the water to remove toxic waste products and then reusing it. In the process of reusing the water many times, non-toxic nutrients and organic matter accumulate. These metabolic byproducts need not be wasted if they are channeled into secondary crops that have economi...

Microcontrollers in Recirculating Aquaculture Systems

Closed-system aquaculture presents a new and expanding commercial opportunity; however, presently there are few profitable commercial operations. Intensive aquaculture systems require a sufficient supply of oxygen and nutrients in temperaturecontrolled water with a means of removing wastes from the system. In properly controlled recirculating aquaculture systems, stocking rates of up to one-hal...

The Bioeconomics of Recirculating Aquaculture Systems Richard

The goal of this study was to produce a detailed aquaculture production model incorporating constraints unique to closed system culture and to conduct a formal economic analysis of closed system operation. Results generated by this model indicate that less than perfect management ability can eliminate the normal advantages associated with using high protein feed. While higher protein levels pro...

Association of mycobacteria in recirculating aquaculture systems and mycobacterial disease in fish.

Mycobacterium marinum isolates cultivated from tissue containing granulomatous lesions in Florida pompano Trachinotus carolinus and from biofilm samples collected from their tank and water recirculating system had identical (L1 of 11 bands) repetitive-sequence-based polymerase chain reaction (rep-PCR) DNA fingerprints. A second M. marinum clone sharing 4 of 11 rep-PCR bands with the first clone...
