Fish Health Management At A Wholesale Facility     Barbara D. Petty   Segrest Farms, Gibsonton, FL     Segrest Farms is one of the largest ornamental fish wholesalers in the U.S. Some of the typical problems which affect fishes received by Segrest Farms include improper handling (net damage, lack of temperature control), poor water quality management, and inadequate control of ectoparasites and endoparasites.  The wholesale facility generates its own problems. Quarantine is not economically feasible, and fishes from different suppliers are mixed in different recirculating systems. The fishes from suppliers’ facilities, which have chronic health problems, are treated during acclimation before introduction to a recirculating system.   Some employees handle fish carelessly, which can result in mortalities.Strict attention is given to performance of biofiltration and sterilization equipment, and water quality. Protocols for efficacious chemotherapeutant application were developed after necropsies were performed. Morts are removed three times a day.  Fish that do not appear normal are “held” and diagnostics are performed.  New recirculating systems have been built which should reduce the potential for spread of pathogens.  Mortality is currently < 3%, and with improved systems and acclimation, it is hoped that the mortality will be further decreased.
