Popis: Preference-avoidance tests using a modified Y-maze test apparatus were conducted with juvenile striped bass, Morone saxatilis, and steelhead (rainbow) trout, Oncorhynchus mykiss (formerly Salmo gairdneri), exposed to a refinery effluent discharged into San Francisco Bay. The test system was set up on site at the refinery, and the performance of the test system was validated using two reference materials, phenol (reference avoidant) and a mixture of amino acids (which was hoped would serve as a reference attractant). Both species of fish were tested at four effluent concentrations ranging from 0.1 to 10% with two different dilution waters, the receiving water and a known high-quality natural seawater. The results of this study indicate that juveniles of both species tended to avoid the effluent at concentrations that might be expected to occur within a short distance of the refinery outfall diffuser. At concentrations that would occur outside the zone of initial dilution, neither species of fish exhibited a preference or avoidance response to the refinery effluent.
