How did the American bullfrog get into bc?

The American bullfrog was introduced to British Columbia in the late 19th century, primarily for use in the culinary market as a food source. They were brought in from eastern North America for frog farming and were later released or escaped into the wild. The species has since established itself in various habitats across the province, often leading to ecological concerns due to its impact on local ecosystems and native amphibian populations.
