Walleye had higher concentrations of mercury than other sport fish. The larger walleye had higher mercury concentrations. Mercury concentrations in the fish ranged from 0.11 to 0.44 parts per million.
“”This is the first study to show that mercury is present in the tissues of a large number of species of fish, and that the concentrations are higher in larger fish than in smaller fish,” said study co-author Dr. Michael J. O’Brien, an associate professor of environmental health sciences at the University of California, Davis, School of Public Health.
“It is important to note that this study was not designed to test for mercury toxicity, but rather to examine the effects of exposure to mercury on the physiology and behavior of the fish in question. It is possible that other factors, such as age, sex, or diet, may have contributed to the differences in mercury levels between the different species.
However, the fact that these differences were observed suggests that there may be a relationship between mercury exposure and the physiological and behavioral changes observed in these fish.” The research was funded by the U.S.
