I have two pallets, which seem to have 4 FHM spawning per pallet. They are not sunk to the bottom, just floating. Several FHM are spawning on the sides of stumps of willows trees that were cut down and treated to kill them back. Of course any rocky area for rip rap has multiple FHM using the rocks to spawn under. I have placed a number of CD's stacked on top of each other using washers to leave a space as spawning structures for my spotfin/satinfin shiners to spawn on. However, the FHM have been using the bottom of each stack to spawn under. There is also a red solo cup that somehow found its way into the pond half buried in the sediment. An FHM is spawning on the inside of the cup. That maybe the cheapest, easiest spawning structure out there Scott. You could just sink several cups with a small stone and scatter them around the perimeter of the pond. When you want to seine, just pick the cups back up... Since they're bright red they'd be easy to find.
