Abstract
The dinoflagellate Cochlodinium polykrikoides isolated from Bahı´a de La Paz, Gulf of California,
showed an important short-term toxic effect on the spotted rose snapper Lutjanus guttatus. This
microalga was able to decrease fish liver catalase activity and lipid peroxidation. Fish exposed to live
dinoflagellates developed an abnormal mucus secretion on the gills that was directly related to algal cell
concentration. Hepatic catalase inhibition and an increase in mucus secretion on the gills occurred when
fish were exposed to 2 3 106 cells L–1 of C. polykrikoides. Lipid peroxidation was significantly different at
4 3 106 cells L–1 and the hepatosomatic index decreased at 3 3 106 cells L–1. Our results suggest that
oxidative stress contributes, at least in part, to the ichthyotoxic effect of C. polykrikoides from the Gulf of
California.
