Abstract

Pink snapper (Pagrus auratus), an endemic Western Australian fish species,was tested for its potential as a bioindicator of aquatic environmental health. Mixed function oxygenase (MFO) induction (as a biomarker of exposure), and sorbitol dehydrogenase (SDH) activity (as a biomarker of liver damage) were of special interest to the study as these biochemical tools have notbeen validated for any Western Australian fish species. Juvenile pink snapper were injected intraperitoneally (l.p.) with 0, 10, 100, 500, and 1000 mug PCB-126 per kilogram. Fish were sacrificed 10 days postinjection, and livers and blood samples were collected for MFO and SDH analysis, respectively. Doses of 10 and 100 Ag PCB-126 per kilogram caused the highest MFO induction, while doses of 0 and 1000 Ag PCB-126 per kilogram did not result in higher MFO activity relative to carrier-injected control fish. SDH activities were not significantly different among treatments indicating that hepatocellular damage was not responsible for the reduced MFO activity at the highest dose. The result of the study demonstrates that pink snapper may potentially be used as a bioindicator species in Western Australia when MFO is used as a biomarker. (C) 2001 by John Wiley & Sons, Inc.
