CB, I noticed you have some tilled fields adjacent to your pond. I'll pass on a comment I got from Kyle. He said to beware if you have drainage coming off of ag land into your pond. If there are any insecticides used on those fields they will most certainly wipe out most amphipods. He said that here in MN he has his best years in ponds adjacent to farm fields when corn is the crop. He has his worst years when soy beans are planted. The reason is that the farmers sometimes use insecticides on soy beans to kill aphids. Apparently it doesn't kill them all because they do come back but kills many of them. Good luck.
