F. de  aEffects of a bacterial inoculum in channel catfish ponds.h[electronic resource]  c1998  aA commercial bacterial inoculum cultured on site called Biostart TM was applied to three channel catfish Ictalurus punctatus ponds at Auburn, Alabama, USA, three times per week from May until October 1996. There were few significant differences (P &lt_ 0.1) in concentrations of water quality variables between ponds treated with bacteria and control ponds. In addition, bottom soil carbon and nitrogen did not differ between treated and control ponds. However, survival and net production of fish was significantly (P&lt_ 0.1) greater in ponds that received the bacterial inoculum than in controls. The mechanism by which the bacterial treatment influenced fish survival cannot be explained from data collected in this study. Further studies of probiotics are needed to define the potential benefits of these treatments to aquacultural production and to determine their mechanisms of action in pond ecosystems.  aalkalinity  aaquaculture  afish  anutrients  aquality control  asoil  awater quality  aBacterial inocula  aTreatments1 aBOYD, C.
