Lepomis gibbosus - Pumpkinseed

French name:  Perche soleil
Dutch name: Zonnebaars
Family: Centrachidae
Group: Fish
Origin: North America
Habitat: freshwater
Introduction:  aquariums and ponds
ISEIA Score : 9
Naturalization in Belgium
First observation in the wild: 1884
Invasion stage: stabilization
Spatial distribution: restricted
Reproduction in the wild: yes
Dispersion potential: medium
Natural habitats: medium
More on invasiveness: Lives mostly in ponds, channels and modified/eutrophicated aquatic environments.
Distribution in Belgium
Established populations
absent from district
isolated populations (1-5 localities per district)
widespread (>5 localities per district)

Impacts on Species
Predation / Herbivory: high
Competition: high
Disease transmission: likely
Genetic effects: low
Impacts on Ecosystems
Nutrient cycling: low
Physical alteration: low
Natural successions: low
Food web alteration: likely
More on impacts: This predatory fish can occur in very high numbers and impact the native fauna by feeding on aquatic invertebrates, larvae of amphibians and fish eggs and fry. It is also suspected to cause food web alteration and is known to host non-native parasites.
