The freshwater fish fauna of B.C. is composed mostly of post-glacial immigrants. These species colonized the province from Columbia, Great Plains and Bering glacial refuges. Many of them now have restricted distributions in B.C. but appear to be in no danger elsewhere. There is, however, a "made in B.C." component to our fauna. The pairs of benthic and limnetic sticklebacks that are indigenous to the central Strait of Georgia region are used as examples of how rapidly diversity can evolve if complete geographic isolation and novel ecological opportunities are available. I argue that we have a particular responsibility to document and protect this "made in B.C." diversity. I also argue that the greatest threat to the conservation of our native fish fauna is the "adipose fixation" of both governmental and private conservation agencies. This attitude leads to the exclusion of fishes other than trout and salmon from fisheries management plans, environmental impact assessments and conservation programs.
