Help released fish survive

Whirling disease

A microscopic parasite is devastating trout and salmon populations in Montana, Utah and Colorado. Infectious spores can exist in mud for up to 30 years.

If you fish United States waters, you are a special risk. Spores spread from one stream to another by sticking to fishing gear.

Wash your waders, boat bottoms and other equipment thoroughly before fishing in a new watershed.

Give a released fish the best chance for survival by following these suggestions:

  1. Use a single hook to release fish more easily. The use of barbless hooks is recommended to make release easier. You can make your hook barbless by flattening the barb with needle nosed pliers.
  2. Minimize the time 'spent' when handling a fish. A fish handled too long may not survive even if released. When handling and releasing, ensure to keep the fish in the water.
  3. When releasing the fish, hold it in the water, gently moving it back and forth. This moves water past the gills and will help revive it. For flowing waters, face the fish upstream. When the fish begins to struggle, let it go.

Barbless hooks are safer for fish. Hooks with barbs do more flesh damage than barbless hooks upon both entry and exit.

Fish consumption advisory (Mercury)

Mercury is a toxin that can affect human health. It can come from natural sources (e.g. soils and sediments) or be transported to the parks (e.g., through the atmosphere) and can then concentrate in top predators. Fish tested in some park waters have elevated mercury levels. Parks Canada, in consultation with Health Canada, has established consumption guidelines and precautionary consumption advice (where no mercury data exist) for women of reproductive age and children (Table 1).

Table 1: Consumption guidelines
Lake Species Women of reproductive age
# of 113 g (4 oz.)

Patricia Lake (Jasper) and Sassenach (Waterton Lakes) Lake trout 4 / month 3 / month
Waterton Lakes Lake whitefish 4 / month 3 / month
Precautionary consumption advice for all other Park Waters Game fish - general 4 / month 3 / month

** A 100g serving is approximately the size of a deck of standard playing cards.
