Features: The Aurora Trout (Salvelinus fontinalis timagamiensis) is a unique genetic stock of the Brook Trout. It is so-named because the colours of its sides are purple. It lives in a few,remote, high- elevation lakes in the Temagami District of Ontario.

Status: Endangered Provincially and Nationally

Range: The Aurora Trout was originally found in two lakes in the Montreal River system, a tributary of the Ottawa River in Ontario. The Aurora Trout has been reintroduced into both lakes where it originally occurred. The fish are now reproducing naturally in one of these lakes. Populations have also been established in some new lakes. The Brook Trout is widespread in North America.

Threats: The Aurora Trout was extirpated in its natural range due to acid rain and other forms of pollution which disrupted reproduction. Low pH from acid precipitation and runoff is a continuing threat to the Aurora Trout in the wild.

Protection: The Aurora Trout is listed under Ontario's Endangered Species Act, 2007, which protects the species in its original lakes from being killed, harmed, captured, or possessed. Aurora Trout have been maintained in captivity by the Ontario Ministry of Natural Resources since they were extirpated from the wild. Reintroduction back into the original lakes, in combination with the addition of lime to the water to neutralize the pH of these lakes, has allowed the population to establish and breed there. In some lakes there is limited fishing allowed. The recovery of Aurora Trout is being guided by the Aurora Trout Recovery Strategy.
