Backyard Aquaponics
A place to discuss aquaponics

I'm trying to create a list of cold hardy freshwater fish/crustaceans/etc that will survive in an aquaponics system. I want to create a nice poly culture and sustainable pond(s). Rarely gets in the - here but I guess theyd have to be species that can handle lows up to -10 F. Any freshwater clams,crayfish, or shrimp anybody could recommend? I'm considering bluegill and perch for fish species, but this thread is to help me get some more ideas.

Channel Catfish are good as well.
Your water itself shouldn't get much below 32 deg F, depending on your salt levels. You may get some ice on the top of your FT though.

I want them to be able to brred/reproduce I heard catfish are picky breeders

I don't know if you'll get much of anything to survive -10, but I've not tried it. One thing to look into is what lives in your native streams and lakes. Bluegill and pumpkinseeds come to mind, although I'd still look at keeping some heat in the tank.

LOL, then I guess there are no fish in Minnesota...............

There are many species of fish suited to the cold but in small waters (most ponds and shallow lakes) winter kill due to lack of oxygen is the problem. To keep fish alive in a small pond you will need to aerate if the ice gets thick or there is heavy snow. Plants can still grow beneath ice if they get sunlight but thick ice or heavy snow blocks out sunlight.
