NOAA has launched the Aquaculture Nutrient Removal Calculator, a tool to estimate the nitrogen removal capacity of oyster farms. This tool is aimed at helping growers provide evidence of the ecological benefits of their farms, such as water cleanliness, during the aquaculture permitting process. The tool requires basic information about the farm, such as the number of oysters harvested and the culture method used, to generate a report on the farm's nitrogen removal capabilities. The results can also be used to educate the community about the benefits of shellfish farming. The tool will be updated with new data and may be expanded to include phosphorus removal and to cover the Gulf of Mexico.
