Yeah, TJ and I were talking about that exact thing via PM. With there being no vegetation, it will most likely be an issue. Until I get the duckweed completely under control adding vegetation is an issue as I am using fluridone to handle the duckweed and any vegetation added would simply be killed by the fluridone. Hopefully I can get the duckweed controlled and then can get suitable vegetation introduced before my sportfish ravage my GS population.
If that doesn't happen the only other factor that may help me is one side of the pond was left with willow trees. They have extremely thick root masses and go out into 2-3 feet of water. Most of that side of the pond is very shallow. Over 6 feet out and it only gets about 2 feet deep. There are extensive areas of 6" or less of water. I observed a fair number of grass shrimp utilizing this maze of roots in extremely shallow water. It will be interesting in the end to see if aquatic vegetation is truly needed for grass shrimp to be successful under predation.
