Completion Report to Virginia Power, Innsbrook Technical Center, Glenn Allen, Virginia. ICMR Contribution series, NO. ICMR-95-02 Institute for Coastal and Marine Resources, East Carolina University and National Biological Survey, South Carolina Cooperative Fish and Wildlife Research Unit, Clemson, South CarolinaStriped bass spawning activity in the Roanoke River, North Carolina, was documented
in 1993 by sampling for eggs at Barnhill's Landing (River Mile 117), which is just
downstream of the spawning grounds between the towns of Halifax (RM 120) and Weldon
(RM 130). Egg sampling was conducted every four hours near the surface and bottom from
16 April to 16 June 1993. Water quality and changes in instream flow caused by water
releases from Roanoke Rapids Reservoir at RM 137 also were monitored every four hours.
During the summer and fall, age-O (young-of-year) striped bass were collected by beach seine
in western Albemarle Sound, and by trawl surveys in western and central Albemarle Sound.
All fish retained in samples were weighed, measured, and aged by counting rings on otoliths.
The date of spawn for each fish was backcalculated, and each fish was assigned to a daily
cohort for calculations of survival rates relative to daily egg production estimates.Virginia Power, Innsbrook Technical Center, Glenn Allen, Virgini
