Dietary Chlosterol Requirement of Juvenile Narrow-clawed Crayfish (Astacus leptodactylus) in a Recirculating Aquaculture System
Dietary cholesterol has been shown to be essential for several crustacean species. However, cholesterol requirement of narrow-clawed crayfish has not been reported. Therefore, a 12-week feeding trial was conducted to determine deitary cholesterol requirement of narrow-clawed crayfish. Juvenile crayfish with an average body weight of 13.8±1 g mean weight were intensively stocked in an indoor rec...
متن کاملBiological phosphate removal in a prototype recirculating aquaculture treatment system
Efforts to reduce phosphorus concentrations in aquaculture systems have mainly dealt with improving the bioavailability of phosphorus in fish feed. Once released into the culture water, phosphorus is generally left untreated and discharged with the effluent water. In the present study, results are presented on a prototype recirculating treatment system originally designed for removal of organic...

15 صفحه اولMicrocontrollers 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...
