How we know

  • 66lakes where an angler logged one in Fish ON-Line; on 48 of them a single trip, one angler’s report

Self-reported by anglers, not a Ministry survey. A lake that isn’t listed may still have them: a lake appears here only once an angler has logged this fish there.

Inland lakes on this list run from 7 to 221,497 acres (median 707) and from 5 to 230 ft deep (median 46 ft).

When and how anglers catch channel catfish

From 92 trip reports naming channel catfish on the lakes above, logged by anglers in Ontario’s Fish ON-Line app. These are self-reported trips, not a Ministry survey: they show when and how people fish for them, not how many fish a lake holds.

Trips by month

The busiest month is July (30% of trips); 5% were logged December–February (lighter bars).

How to recognize it

A long, scaleless catfish with a steel-blue to grey back, pale belly and eight dark whiskers; the sides often carry small black spots. The tail is deeply forked and the snout more pointed than a bullhead's.

Don’t confuse it with

Brown bullhead — Brown bullhead has a square tail and blunter snout, and is usually much smaller.

Life in an Ontario lake

Channel catfish are the largest catfish in Canada. In Ontario they are common in the south, including Lake Huron, Georgian Bay, Lake Simcoe, Lake St. Clair, Lake Erie and Lake Ontario, and in large rivers such as the French, Ottawa and upper St. Lawrence; they also occur in the northwest. They favour deep holes over sand, gravel or rock, often in current below dams and riffles, and feed by day and at night.

Spawning runs from late spring into summer, often after a move into rivers, with eggs laid in sheltered spots such as undercut banks, logs or rock piles and hatching in about a week. Growth in Ontario is slow and the fish are long-lived: ages of up to 40 years have been reported.

Rules and eating

Before fishing, check the current Ontario Fishing Regulations Summary for your Fisheries Management Zone, any exceptions for the waterbody, and your licence type. Angler catch reports show what people logged, not what is legal to catch or keep. Fish ON-Line itself (how to use it) maps the zones and exceptions. Before eating fish from a particular lake, check the Guide to Eating Ontario Fish.
