Tidal Freshwater Communities
An electrofishing survey of fauna composition in South Edisto and Combahee rivers began in May 2001. Sampling is conducted monthly in conjunction with the Inshore Fisheries Section, and it occurs when the water is restricted to the river channel (mid-ebb through mid-flood tidal period). The salinities at the saltwater freshwater-dividing line on the Comhahee River returned to normal levels during fall of 2002, and ACE began surveying downstream of the dividing line. Faunal composition is examined with regard to changes in salinity and habitat types.
