Water re-use system for production of fingerling fishes in Brazil with emphasis on South American catfishes (Rhamdia quelens and R. sapo)
, and
An indoor tank facility supplied with recirculated water and incorporating biofiltration was constructed in 1981 at the Fishculture Station of the Federal University of Santa Maria, Brazil. The system has proven extremely effective for maintaining water quality for the production of fingerling fishes. South American catfishes (Rhamdia quelen) have been successful reared for 12 months from egg incubation within the system. Other species which have been maintained in the system 1-3 months include R. sapo, common and mirror carp (Cyprinus carpio) and tilapias (Tilapia nilotica and T. rendalli). In addition to a description of the water re-use system, the basic biological and chemical mechanisms that underlie its use are reviewed
