Public health officials issued the advisory due to elevated levels of mercury and polychlorinated biphenyls found in the tissue of resident fish. The species of concern include bass, bluegill, yellow perch, crappie, walleye, carp, catfish, suckers and sturgeon.
Officials say eating too much of the contaminated fish can cause negative health effects such as damage to the nervous system, organs and reproductive system.
The advisories are in place between the Bonneville Dam to Ruckel Creek and Ruckel Creek to the McNary Dam.
Officials say pregnant women and young children are most vulnerable to the health effects of mercury and pcbs.
The advisories do not affect migratory fish species such as salmon, steelhead, American shad and lamprey.
