Evidence of Natural Reproduction of Aquaculture‐Escaped Atlantic Salmon in a Coastal British Columbia River
Abstract: We present evidence of the first successful natural spawning of Atlantic salmon ( Salmo salar ) documented on the Pacific coast of North America. Twelve juvenile Atlantic salmon composed of two year classes were captured in the Tsitika River, British Columbia. We analyzed restriction‐lengt...
