we are also in n. wis., had rainbows for two yrs, they were 5-7"when put in the pond. One yr later avg 12-13", they had been fed pellets and lots of minnows and tadpoles. Then that fall and next yr, we could not catch or find a one. No reason just gone. Even the hbg are gone. Put in the largest you can justify and keep whatever u catch is our opinion. Or something else will. We ran our aerator 24/7 in the winter and at nites in the summer/ Good luck
Nils,
You are probably in a very difficult area for what you want to accomplish.
To add to it, how "northern" are you? Superior and Ashland, vs. places just a few miles south, like Eau Clair, Oskosh, or Milwaukee are worlds different from each other
Questions are very welcome. We have a lot of experts for areas all around the the country.
Regards,
Ken
