Atlantic salmon grow best in sites where water temperature extremes are in the range 6-16 C, and salinities are close to oceanic levels (33-34 per cent). Atlantic salmon later became a vital resource for European settlers who entered the Lake Ontario region in the late 17th century. Fish Man. After a couple of years, these fish migrate to the ocean, where they undergo a great deal of growth before reaching sexual maturity. They are not fed or injected with dyes. In addition to the Don River and Toronto bay, the Credit river proved to be a prime salmon fishing location and was a favoured site among local First Nations groups. This view is expanded upon by O.F.A.H.s report that suggests that the abundance of salmon encouraged settlement of the interior of Canada (meaning, at the time, Ontario) (O.F.A.H., 2007: 3).

They provide information about threats to salmon and the methods we use to study salmon survival and migration. It has been brought to our attention that this Red Skin Disease has reappeared in some areas. Unfortunately, overfishing and dams that blocked their ability to reach their preferred spawning grounds, reduced their numbers until populations were greatly diminished.
