鮭魚科學館 / Sapporo Salmon Museum

在鮭魚科學館（位於札幌市南區）繁殖與展示著從鮭科的魚類到各式各樣的水生生物。豐平川過去是許多鮭魚會迴游的河川，但因為隨著札幌市的發展而受到污染。一時之間變得完全看不到鮭魚迴游。然而經過了1978年的鮭魚返鄉運動的努力，終於改善了河川的環境，鮭魚又回來了。

Sapporo Salmon Museum (Sapporo City Minami-ku) is a facility to breed not only salmon but other water creatures, and exhibit them. The main purpose of this free admission museum is to educate people about ecology. Toyohira River, which runs through the city of Sapporo, was clean enough for salmon to live in former days, but it deteriorated due to Sapporo's development and they disappeared from the river. However, the 'Come Back Salmon' Program started in 1979 as a citizen's public campaign. This resulted in environmental improvement and a lot of salmon returned after three years of their release.
