Short season fish/crustaceans

Hello all, I’m wondering if anyone else with a similar weather situation as me(MB Canada) grows fish or prawns outdoors over just one season? I’m limited in pond depth by my municipality, so I’m unable to dig deep enough to prevent complete winter kill (we get 3-4’ of ice on moving rivers here in winter, and I can get away with 3 maybe 4’ of depth at the deepest, closer to 2’ for most of it realistically) We have usually 7 reliably ice free months but the beginning and end of that period would have quite cool water temps. My dream would be trout of some kind but I’m under the impression that would be a multi year situation, and I’m not a huge fan of the faster whitefish like basa(just as an example). Can I get away with prawns in a short season? I’ve seen several people online grow them to edible size in pools over just a few month period. Due to space I’m also only able to build a pond on the smaller end, around 7-800sqft. Go easy on me, green as grass over here
