I did get 700+ glass shrimp from TJ last fall but have not found any in my recent rake surveys or seen any of them in shallow water.
My rake surveys have turned up at lot of tadpoles, small GSH, YOY RES, damzel fly larvea, dragon fly larvea, a few large leeches, a few fingernail clams, at least one large FHM, one large leopard frog, and one walking stick, but no glass shrimp. Despite that I think they are still present in the pond.
