With your Wyoming fishing license, you are permitted to harvest fish, in accordance with creel limits, for consumption. Fish can be a healthy addition to one’s diet, but anglers should be aware that consumption advisories have been developed by Wyoming Game and Fish Department for the following species of fish in the park: cutthroat, brown, and lake trout as they may contain methyl mercury.
Mercury can build up in tissue over time and consuming too much can pose health risks. These advisories are in place to keep the consumption of mercury within safe levels.
The advisory includes information specific to sensitive individuals, which include women who are or might become pregnant, nursing mothers and children less than 15 years of age; as well as all other persons.
Advisory data is based on Wyoming Game and Fish Department tests to assess mercury levels in fish harvested from the Snake River and Jackson Lake. Each advisory provides specific fish consumption recommendations for fish from those waters.
For other waters and fish in the park, we recommend following this FDA guidance on wild fish consumption:
It is recommended that women of childbearing age and young children avoid those species of fish and seafood known to contain high concentrations of mercury. For women and young children, the Food and Drug Administration (FDA) and Environmental Protection Agency (EPA) currently recommend against eating any shark, swordfish, king mackerel, and tilefish, and also limiting consumption of albacore tuna to one meal per week.
Women and young children will receive the health benefits of eating fish without undue exposure to the harmful effects of mercury by eating up to 2 meals per week (A meal is 8 oz. of uncooked fish or 6 oz. of cooked fish) of a variety of fish and shell fish that are low in mercury. Some commonly eaten fish that are low in mercury are Wyoming caught rainbow trout, cutthroat trout, and kokanee and shrimp, canned light tuna, salmon, Pollock and catfish from stores and restaurants. The 2 meals per week include fish from all sources, and should be the total of Wyoming caught fish and fish purchased at stores and restaurants.
Aquatic Invasive Species
PREVENT THE SPREAD OF INVASIVE SPECIES - CLEAN. DRAIN. DRY.
Aquatic invasive species (AIS), such as zebra or quagga mussels, Eurasian milfoil and curly pondweed, are a serious ecological and economic threat to the Greater Yellowstone Ecosystem. Boats, waders, and anything else that comes in contact with a body of water has the potential to spread non-native plants, pathogens, and other invasive species from one water body to another.
Never empty containers of bait, fish, plants, or animals into park waters.
