State Warns About Mercury Levels in Local Fish

US - State scientists are recommending that children and women who are pregnant or breast-feeding avoid eating bass and sturgeon caught in the Sacramento River and upper Delta because of mercury contamination.

This warning is the latest in a series of advisories issued over the years for fish that can accumulate mercury washed from long- abandoned gold mines.

This time, however, researchers did more than just examine fish tissue. They checked the other end of the fishing lines – the anglers.

Many of them were bagging species not usually included in fish consumption reports: pikeminnow, hitch, sucker, carp, goldfish and Asiatic clams. Researchers previously had targeted more popular game fish such as striped bass, sturgeon, trout and salmon.
