BC Distribution and Notes This eastern North American fish is an attractive little pest. It competes with native species and has extirpated some scientifically valuable stickleback populations on Vancouver Island. It is still spreading on Vancouver Island and the B.C. mainland. Apparently, people keep small pumpkinseeds as aquarium fish but release them when they get too big or become a nuisance. Thus, in B.C., humans almost always spread this species.
