Striped bass (Morone saxatilis) inhabiting Albemarle Sound and its tributaries support important recreational and commercial fisheries in coastal North Carolina. The major spawning area for Albemarle Sound striped bass is located in the Roanoke River, which discharges through several channels into the western end of Albemarle Sound. Since the mid-1970s, these fisheries have suffered due to reduced numbers of harvestable adults. Studies on egg abundance and viability have been conducted each year since the mid-1950s by Dr. W. W. Hassler and co-workers from North Carolina State University in Raleigh. The study has several objectives in mind: (1) to continue the data base established by Dr. Hassler; (2) to develop a method to backcalculate Hassler's data in an egg density-per-unit-volume format (to compensate for changes in the flow regime); and (3) to relate striped bass spawning activity (as measured by egg production) to water releases from the reservoir at Roanoke Rapids, North Carolina.
