متن کاملResearch Article: The effect of media biofilter and aquatic plant (Ceratophyllum demersum) on water quality of recirculating aquaculture systems, growth and survival rates of ornamental fishes
This study was conducted in order to compare the hornwort aquatic plant (Ceratophyllum demersum) with an artificial filter for purification in a recirculating aquaculture system (RAS). At first, the fluctuation of nitrogen components of the water reuse system equipped with artificial filtration was evaluated. Experiments were performed during three months. The hornwort aquatic plant was collect...
متن کاملMicrocontrollers 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...

tion method when temperature, salinity, disease, water supply, land availability, or exotic species /environmental regulations prevent more cost effective alternatives. A recirculating aquaculture system (RAS) can also be used to support traditional pond or net pen culture through broodstock or fingerling production. Recirculating systems have been widely used in research laboratories and unive...
متن کاملReducing the Environmental Impact of High-density Fish Production: an Integrated Approach to Solids Treatment for Recirculating Aquaculture Systems Using Expandable Granular Biofilters
Over the past decade, the environmental impact of wastes discharged from high-density flow-through fish-production systems has been viewed with increasing concern. Recirculating aquaculture systems are gaining wider acceptance because of their ability to reduce waste discharges, improve quality control, and reduce costs. The crucial processes that must be addressed in treating recirculating wat...
