ABSTRACT Sophisticated, carefully engineered biological filtration systems have the potential of being the least costly and most efficient method for the maintenance of good water quality (necessary for proper health, feeding, growth, and reproduction of the cultured organisms) in closed or semiclosed aquaculture systems. However, certain questions need to be answered. For example, what constitutes a “good” biological filter community under a given set of environmental conditions (salinity, temperature, flow velocity)? Are there particular “indicator” species whose population changes signal changes in the efficiency of the biological filtration system? What is the role of predation and cropping of the bacterial populations in the system? Some tentative answers are suggested to these and other questions.
