children. Mercury contamination is contained in the muscular tissue of the fish, instead of the fat tissue like other contaminants. These larger predatory fish like the Largemouth and spotted bass become more contaminated, by biomagnification, as the mercury moves up the food chain. Producer organisms become contaminated, then the fish that eat them can become 10 times as contaminated as the level of the food chain below them, this contamination increases in strength as it moves up the food chain to these top predators in the environment. The contamination levels in other fish like the crappie, blue gill, shellcrackers, and catfish were all listed as safe to consume.
