Pearl Dace

Habitat Distribution

• Native across most of Canada — from Nova Scotia and Newfoundland through Quebec, Ontario, and the Prairie provinces west to eastern British Columbia, and north into the southern Northwest Territories.
• Strongly associated with cool, clear headwater streams, bog ponds, and small lakes; avoids warm, turbid lowland water.
• Prefers silt, sand, or gravel bottoms close to aquatic vegetation in both lake and stream settings.
• Most common where large predatory fish are absent — isolated bog ponds and upper-reach streams are prime habitat.

Key Locations

• Ontario — widespread across the Canadian Shield and northern drainages; one of the more commonly encountered small minnows in cool headwater systems.
• Nova Scotia to Newfoundland — native across Atlantic Canada's cool stream and bog-pond systems.
• Prairie provinces — present in isolated cool-water pockets and headwater streams from Manitoba through to eastern British Columbia.
• Southern Northwest Territories — reaches the northern edge of its Canadian range in cool drainages here.

Specific Spots

• Pool edges and slow backwaters in small headwater creeks, where current is minimal and gravel or sand bottom is visible.
• Near aquatic vegetation in bog ponds and small lakes — weed edges provide cover from the few predators present.
• Shallow, well-oxygenated areas of cool ponds; Pearl Dace avoid the warm surface layer that develops in summer.
