These aquaria, used to culture selected marine organisms, were provided with thermally regulated water (either 20, 25, 30, 35 C or ambient) taken from the discharge canal of a power plant on upper Galveston Bay, Texas. Aufwuchs accrual was influenced by temperature, salinity, and species cultured. Sedimentation rates due to the supplemental feeding of organisms and sloughing from the Aufwuchs community were as great as 7/ml/liter per day. Biological fouling and accumulation of sediments limit growth and production of intensively cultured organisms by lowering dissolved oxygen levels and producing anaerobic substrates. Organisms which feed by grazing can be effectively used to minimized substrate fouling in mariculture operations.cultured organismsdissolved oxygen (DO)aquariagrowthsedimentationtemperaturesalinitygrazingpower plantsmaricultureChapter
