Invasive Animal

Yellow Perch

Perca flavescens

About This Species

Yellow perch are native and widespread East of the Rocky Mountains, from Alberta to Nova Scotia and North to the Northwest Territories. They have been intentionally released in BC as stock fish and from aquariums and private ponds, and accidentally spread by boats and in bait buckets.

Yellow perch are predators of other fish species, insects, and tadpoles. They reproduce quickly and may overwhelm and outcompete native predatory fish for food and habitat.

How to Identify

Yellow perch are 10-25 cm long, with an olive green back with 7 thick dark stripes and a silver belly. They have two dorsal fins, a forked tail, and a small hump just behind the head.

They are widespread in the Lower Mainland and on Vancouver Island, and in the Pend d’Oreille, Kootenay, and Okanagan watersheds. Two populations exist in Charlie Lake and Swan Lake in the Peace region, but these may be considered native to BC.
