Well, that's great news knowing that the FHM can actually get under something lying flat on the bottom of the pond to spawn under. Perhaps large roofing panels could just be laid on the pond bottom to really enhance the spawning numbers of FHM's. Yesterday I saw quite a lot of very small surface water disturbances that I thought might be new spawns but I couldn't see for sure because of the light glare off the water.
My pond has evolved over the years from a groomed fishing pond to a natural nature pond where something exciting is constantly taking place from day to day. So I do want plants like American Elodea and my main submerged plant is curly leaf pond weed. I want them controlled somewhat so I am putting in 6 GC this Friday.
American waterweed (American Elodea) is an important part of lake ecosystems. It provides good habitat for many aquatic invertebrates and cover for young fish and amphibians. Waterfowl, especially ducks, eat this plant. The plant is narrow and a dime would cover the leaves from side to side.
