There are zero possession limits for many native species. You must correctly identify your catch. If you are not sure, release it immediately.

Maximum daily catch and possession limit 2

Note: If a fish has been filleted, two fillets will be considered one fish.

It is unlawful to: 

  • continue fishing on any day after having caught and retained the maximum daily catch and possession limit. 
  • possess more than 2 game fish at one time.

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. Minimize the time you play a fish. A fish played too long may not survive even if released. Remember to always bring fish up from depth slowly. Fish brought up too quickly will rupture their air bladders and die. 
  2. Be gentle, keeping the fish in the water at all times when handling and releasing. 
  3. Handle the fish with bare, wet hands. Keep fingers away from the gills and do not squeeze; this may cause internal injury, gill or scale damage. 
  4. Remove the hook gently with needle-nosed pliers. If the hook is deep, cut the leader rather than pulling the hook out. The hook will decompose in time. Most fish survive with hooks in them. 
  5. Continue to hold the fish 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. 
  6. If the fish is bleeding excessively, it will likely not survive if released. Kill it and include as part of your catch if permitted. 
  7. The use of barbless hooks is recommended to make release easier. Hooks can be made barbless by flattening the barb with needle-nosed pliers. 
  8. Single hooks are recommended to release fish more easily. 
  9. Continuing to angle for trout in waters exceeding 18° C reduces the ability of these fish to survive the ‘catch and
    release’ process.

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.)
servings**
Children (under 15 yrs)
# of 70 g (2.5 oz.)
servings**
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.
