Prussian Carp
Prussian carp are an invasive fish that showed up in Alberta around 2006 — likely through an accidental goldfish release — and have since spread across multiple Alberta river watersheds and into Saskatchewan.
Anglers encounter them regularly while fishing for trout and other species. Because they're invasive, catching and removing them is encouraged, and there are legal obligations if you land one.
Also known as Silver Prussian Carp, Gibel Carp
- Deep-bodied and plump, silver-gold in colour with darker shading along the back; large, clearly defined scales (29–33 along the lateral line).
- Nearly identical to wild-type goldfish — DNA testing is the only reliable way to tell them apart when goldfish have lost their orange colour in the wild.
- First ray of the dorsal and anal fins is strongly serrated, a useful in-hand ID feature that separates them from native suckers.
- Typically up to 30 cm long; can reach 45 cm and up to 3 kg, though most caught in Alberta run considerably smaller.
What to know
Habitat Distribution
- Introduced, not native — first confirmed in North America in Alberta in 2006, suspected through an accidental goldfish release; now established across the Bow, North Saskatchewan, Red Deer, Oldman, South Saskatchewan, and Rosebud watersheds.
- Spread into Saskatchewan through shared waterways; Ontario has regulated them as prohibited under the Invasive Species Act to prevent their arrival there.
- Thrive in warm, shallow, low-oxygen water — irrigation canals, river backwaters, urban stormwater ponds, small prairie lakes, and stocked trout ponds.
- Tolerant of poor water quality and high turbidity — conditions that exclude most native Alberta fish — which helps them establish quickly in degraded systems.
Key Locations
- Bow, North Saskatchewan, Red Deer, and South Saskatchewan river watersheds — the core of the established Alberta range.
- Spring Lake and East Pit Lake (central Alberta) — stocked trout fisheries where Prussian carp have become a regular incidental catch.
- Blood Indian Creek Reservoir (eastern Alberta) — an active management and research site with a known population.
- Urban ponds and irrigation canals around Edmonton and southern Alberta — consistent catch locations reported by local anglers.
Specific Spots
- Shallow, weedy margins are prime territory — they spawn on submerged vegetation and feed heavily in the shallows, especially in warm months.
- Irrigation canal inflows and backwater sloughs hold concentrations; slow or still water with soft bottoms and heavy nutrient loads suits them well.
- Urban ponds and stocked trout fisheries like Spring Lake and East Pit Lake in central Alberta have documented populations — check the bottom-feeding zones near weed edges.
- Blood Indian Creek Reservoir in eastern Alberta is an active research site for population control; anglers there encounter them regularly.
Prussian Carp FAQ
Answers from onWater's species guide.
What are the best lures and bait for Prussian Carp?
Dough baits, bread, and sweet corn fished on the bottom are the most consistent producers, they match the bottom-feeding, plant-and-detritus diet directly. Small worms or worm pieces under a float also work well, especially in shallower ponds and canal margins.
When is the best time to fish for Prussian Carp?
Spring and summer, feeding activity increases as shallow water warms; spawning fish concentrate in weedy margins and are easier to locate. Fall, still catchable as temperatures drop, though activity slows in colder water. Winter, survive under ice but largely inactive; not a practical target season.
How do you catch Prussian Carp?
Most Alberta anglers encounter Prussian carp incidentally while fishing for trout or other species, but some specifically target them to help remove them from the system. Bottom fishing with dough bait or corn from shore in shallow, weedy ponds and canal margins is the standard approach.
What do Prussian Carp eat?
Bottom feeders that graze on plankton, aquatic invertebrates (worms, insect larvae), plant material, and detritus, small dough baits, corn, and worms fished on or near the bottom match this feeding style directly.
Where do Prussian Carp live?
Introduced, not native, first confirmed in North America in Alberta in 2006, suspected through an accidental goldfish release; now established across the Bow, North Saskatchewan, Red Deer, Oldman, South Saskatchewan, and Rosebud watersheds.
