Interpretive Summary:

Technical Abstract: Flue gas desulfurization gypsum (FGDG) is a byproduct from fossil fuel power plants. This material, which has typically only been used in agricultural settings, is now being tested in aquaculture ponds as a way to increase hardness, reduce available phosphorus, and control algal blooms. A field study was conducted at a catfish aquaculture farm in Alabama to investigate the effects of FGDG on water quality and the algal community. The results from this 6-month study and future directions will be presented.
