How we know

  • 154lakes where an angler logged one in Fish ON-Line; on 89 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 526) and from 5 to 300 ft deep (median 50 ft).

When and how anglers catch bluegill

From 345 trip reports naming bluegill 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 (27% of trips); 6% were logged December–February (lighter bars).

How to recognize it

A round, deep-bodied sunfish, green to brown with faint dark vertical bars. Look for a solid black ear flap with no pale edge or red spot, and a dark blotch at the back of the dorsal fin.

Don’t confuse it with

Pumpkinseed — Has a red or orange spot on the tip of the ear flap and wavy blue-green lines on the cheek.
Hybrid sunfish — Bluegill and pumpkinseed commonly cross in Ontario, so a sunfish with a mix of both species' marks may be a hybrid.
Rock bass — Has a large red eye, rows of dark spots, a bigger mouth and six anal spines instead of three.

Life in an Ontario lake

Bluegill prefer warm lakes and ponds and shallow, weedy bays of larger lakes, in fairly clear water. They are plentiful in many southern Ontario waters, including the lower Great Lakes, the Kawarthas and the Rideau Lakes, and also occur in some waters of central and northwestern Ontario such as Quetico Provincial Park. They tolerate warm water and low oxygen and often travel in schools.

Bluegill spawn later than pumpkinseed, usually by two to three weeks, with activity peaking in early July. Males clear nests down to hard bottom in shallow water and guard the eggs and young for one to two weeks. Growth is quick at first and then slows: a 17.5 cm (7 in) fish may be about six years old and a 22.5 cm (9 in) fish ten or older.

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.
