Yellow perch

Perca flavescens

About This Species

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

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. They’ve been shown to impact salmon growth and survival, as well as carriers of parasites. Yellow perch are designated as a Regional Containment/Control species by the BC Provincial Priority Invasive Species List. 

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. 

Take Action

Prevention is the best approach.



It is illegal to move fish between waterways in BC. The use of live finfish as bait is strictly prohibited in BC.
