Find it

Where, when and how deep to look.

Where to find it

Found from Ontario Great Lakes, Northern Ontario, Canadian Prairies and Yukon, NWT & Nunavut. Cold lakes across Canada and the Great Lakes, especially Lake Simcoe, Georgian Bay, Lake Huron and the big prairie and northern lakes.

Habitat

Cold lakes across Canada and the Great Lakes, especially Lake Simcoe, Georgian Bay, Lake Huron and the big prairie and northern lakes.

Depth

20–100 ft.

Best time

Any time of day; morning is best in shallow water.

Best tides

No tide.

Best weather / conditions

Calm days for jigging deep water; cold, windy days in spring keep fish shallow.

What to tie on and what to throw.

Best bait

Small minnows, salmon eggs and wax worms on small hooks.

Catch it

Step by step, from first cast to landing.

Step-by-step: how to catch it

  1. Go where it lives: Cold lakes across Canada and the Great Lakes, especially Lake Simcoe, Georgian Bay, Lake Huron and the big prairie and northern lakes.
  2. Rig up: 7 ft medium spinning or casting rod; downriggers or lead-core line for trolling deep. 10–15 lb fluorocarbon.
  3. Pick your bait: Small minnows, salmon eggs and wax worms on small hooks. Lures: Small jigging spoons with a 'teaser' fly above them.
  4. Fish it: Mostly an ice-fishing fish: jig a small spoon on the bottom, then lift it slowly and hold it still. Whitefish have soft mouths, so set the hook gently.
  5. Time it: Any time of day; morning is best in shallow water. No tide.
Fishing techniques

Mostly an ice-fishing fish: jig a small spoon on the bottom, then lift it slowly and hold it still. Whitefish have soft mouths, so set the hook gently.

BigJoe's tip

Watch your flasher (sonar). Whitefish often come up off the bottom to look at the lure, so stop jigging when you see one rise.

Catch and release

Catch and release: wet your hands, keep the fish in the water when you can, and release it quickly. Use circle hooks and a dehooker.

Clean & cook

Is it good to eat, and how to prepare it.

Edibility

Excellent eating — one of the best-tasting fish in its range.

Cleaning

Bleed and ice it right away. Fillet, then remove the skin and any dark bloodline.

Cooking suggestions

Mild, white, flaky and rich in oil: one of the best smoked fish there is, and the classic Great Lakes fish fry.

6

Stay safe & legal

Safety, rules and taking care of the fishery.

Safety warnings

Cold water kills fast — wear a life jacket on big northern lakes, and test ice before you walk on it.

Regulations

Check local limits; some lakes have whitefish seasons tied to the ice-fishing season. Licenses, limits and seasons are set by each province, territory or state, and many lakes and rivers have special size limits, slot limits or closed spawning seasons — check the current regulations for the water you fish.

Conservation

Keep only what you'll eat, release the rest quickly, and follow size and bag limits.
