Water quality is often the most critical element of pond management, either for aquaculture or sportfishing purposes. For more information check out our publication on managing water quality for fish. Additional information on farm ponds and their management can be found in our farm pond management publication. The Iowa Department of Natural Resources has a web page on pond stocking. They also have a pamphlet on managing a stocked pond that includes information for licensed aquaculture units that sell fish in Iowa.
