I think that I stocked them this spring, but have not seen them since release, but the pond is 1 acre and I have not seen much but FHM. The submerged plants are thick near the edges, so I am not surprised. I figure that I'll stock a few SMB no later than 2017. I may also stock a small number of GC if the weeds do not subside with the goal of reduction rather than elimination. I am planning to slowly raise the water level a few inches a year once the marginal plants get thick, with the total increase being 12 inches over 3 years. I did this on my last pond once the bald cypress got going and I liked the result. I use inlet boxes from AgriDrain to do this. So far, it has worked out well.
