Other exotic species are maintained in the ecosystem through management of fish stocks. For example, many of the salmon species found in the watershed are actually native to the Pacific coast, but were originally stocked into Hamilton Harbour or Lake Ontario for sport fishing and/or control of alewife populations.

Others, like Ebener, say the biggest problem is the 6-inch alewife. They exploded by the 1950s and 1960s because there weren’t enough lake trout left to control them.
