Dang, sorry to hear that news. I was hoping that your fish were just being persnickety.
Are you able to easily drain down your pond so you can perform a fairly comprehensive seine survey?
If you are now forced to start over, then I think you really need a good handle on exactly what is left in your pond. Re-stocking with fish that are quickly converted into CC forage would just be throwing in more good money.
Perhaps open a new thread about starting over? You might be able to get some good advice from the experts here that manage ponds for a living.
