Also, we are gonna restock it just in case but with less amounts of fish. Do you think we will have too much of a problem with the bigger fish in there now eating the new ones?
We put in 7 grass carp in when we first built the pond and they have kept the pond very clean. We haven't had a problem yet with them in there. So I dont think it could be because of that.
If you have large bass in the pond and you put juvenile fish in it then yes they will munch up every one they can catch before they hide. If you have fish still in the pond you could always see if they breed on their own. Good luck.
Your plants under your ice still need sunlight for photosynthesis. If not, they die and decomposing plants absorb oxygen that fish need.
In the future, and I apologize if this has been mentioned, see if you can get an ATV with a blade out there and get some of that snow off the ice so the sun can penetrate to the plants below.
a cople side notes,
when restocking, use hibred gills, "they dont repopulate so you dont have to wory about to many or stunted gills, you can restock them every few years so yo will have plenty of monster gills to harvest.
plant plenty of minnows,
never hurts to put in an automated fish feeder that will turn on for a couple seconds once a week.
there are machanical and electrical aireators. look though them to find what best suits your particular situation. some people use fountains so the pond never freezes in the winter, others bubblers.
another item you can look at is things some home owners use to keep thier docks from freezing solid in the winter so they can leave thier boats in year round.
another thing about winter kills in spring fed ponds, some figure it as always being lack of oxigen, there is another thought, and that is preasure. compactes snow and ice build up on top the ice can add tons of water presure to small lakes and ponds. cutting holes in the ice in the winter can releive these presures. "so having one or two trusted fishing buddies who you can trust to fish the pond in the winter with out taking a hundred guys out with them can be a big asset.
