pollution, a hydrographic and meteorological survey, and a bacteriological survey of grow- ing waters (NCDMF 2015) . Sanitary surveys are conducted for all potential shellfsh-growing areas in coastal North Carolina and recommendations are made to the NCDMF which areas should be closed for shellfsh harvesting. Waters are classifed as either ‘Approved,’ ‘Conditionally Approved,’ or ‘Prohibited’ based on the analysis of the data collected from each sampling station. Tere are 16 designated shellfsh harvesting areas around the Albemarle and Currituck sounds that are considered impaired and classifed as Prohibited for the harvest of any oysters, clams, or mussels. 4.5.14.3 Aquatic Species Tere are six freshwater fsh SGCN in the basin. Appendix G provides a list of SGCN and other priority species for which there are knowledge gaps or management concerns. Appendix H identifes SGCN associated with aquatic communities found in this river basin. Table 4.75 identifes the SGCN found in the Pasquotank River Basin. 4.5.14.4 Threats Affecting Aquatic Species Te cumulative efects of nonpoint source pollution are the primary threat to water qual- ity across the state and throughout the Pasquotank River Basin. Te presence of non- point source pollution can be identifed through the NCDWR basinwide plan and the NCDMF sanitary surveys, but actions to address these impacts must be taken at the local level. Without proactive land-use planning initiatives and local water quality strategies,
