My 2 acre pond was stocked with CNBG, RES and FHM this fall. LMB and HSB are going to be stocked later this year. I placed rock, tree tops and pallets in the pond for structure. I also want to stock addition forage like bullfrog tadpoles, paper-shell crawfish and possibly grass shrimp. It is a old pond that I renovated and does not have any vegetation. My questions are do I need vegetation, if so what types and what are the disadvantages of adding vegetation? The pond is located in North Alabama.
