Fish caught on record banner

Fish are prolific animals in our collections!

These records typically document “fishy” things that have been most important to people—especially fishing. They also show the ongoing influence of human actions on fish populations, whether it be the effects of settlement and industry or the management of fish stocks.

Our collections feature many records documenting fish meeting their fate. This photo of a family of American tourists also reflects the economic importance of fishing as a draw to prospective visitors from south of the border since the 19th century.

Commercial fisheries have been present on the Great Lakes and other areas of Ontario for centuries. Fishing was one of the first industries established by European settlers in the province, and it plays a key role in the local economies of many Indigenous communities.

Sea lampreys look straight from a horror film! These underwater predators use their sucker-like mouths to drain the blood of their prey.

Lampreys also illustrate the environmental impact of humans. Originating in the Atlantic Ocean, lampreys were first seen in Lake Ontario in the 1830s after completion of the Erie Canal. After expansion of the Welland Canal in 1919, the species spread to Lake Erie and eventually the rest of the Great Lakes.

By the 1950s, lampreys had devastated populations of lake trout, a popular species for commercial and recreational fishers. One solution—mechanical barriers—didn’t work. The Canadian and US governments responded by establishing the Great Lakes Fishery Commission. By 1962, the lamprey crisis had subsided, following the application of a chemical that killed lamprey larvae.
