Trends We calculated the acreages and percentages of the three categories of shellfishing growing areas in Narragansett Bay at five-year intervals between 1995 and 2015 (Table 3). The percentage of the Bay classified as approved and conditionally approved appears to have slightly changed when calculating acreage and percent change across the Bay. However, more apparent changes are shown in the Bay regions (Table 4). Table 3. Area (acres) and percentage of shellfish growing areas by category in Narragansett Bay at intervals from 1995 to 2015. Category Approved Conditionally Approved Prohibited Year Acreage Percent Acreage Percent Acreage Percent 1995 82,386 66 14,807 12 27,903 22 2000 80,856 65 14,322 11 29,938 24 2005 79,753 63 14,612 12 31,667 25 2010 79,180 63 15,175 12 31,578 25 2015 79,253 63 16,297 13 30,542 24 Changes in shellfish growing areas by category in Narragansett Bay at 5-year intervals. Bars Figure 2. represent change in acres. Dotted lines/points are percent change. We also calculated the amount of change in area by category for the five Bay regions at five-year intervals from 1995 to 2015 (Table 4). Results for the entire Narragansett Bay are summarized in Figure 2. Of note, the Upper Estuary had an increase of approximately 1,100 acres in conditionally approved areas from 2010 to 2015, while prohibited areas decreased by approximately the same amount (Table 4; Figure 3).
