I do not have an outdoor pond nor am I planning on making one anytime. I am just curious. I see a lot of these youtubers from florida that have bass, red tail catfish, gars and all sorts of monster fish in their backyard ponds. I was wondering what kinds of fish can survive a pond in canada other then koi or goldfish all year long. i would love to have a back yard pond someday if i ever get the space. This year it has been probably one of the coldest winters compared to the past few years -15 to - 20+
