Sampling to estimate production and viability of striped bass eggs was conducted at Barnhill's Landing on the Roanoke River, North Carolina, from 15 April to 15 June 1989. A total of 4,722 eggs was collected in surface nets: first eggs appeared in samples on 16 April and continued sporadically until 9 June, when the last eggs were collected. Estimated striped bass egg production in the Roanoke River for 1989 was 637,919,162 (S.D. = 27,668,383) eggs. A potential major spawning activity at the end of April was terminated by high and prolonged reservoir discharge, which forestalled peak spawning until the last week in May. Seasonal egg production was 50% complete by 26 May, 80% complete by 29 May, and 99% complete by 2 June. Egg viability was estimated as 41.8%, the seventh lowest on record. Major egg deposition ensued when water temperatures reached 18 deg. C. Approximately 89% of all eggs was collected at water temperatures between 18 and 21.0 deg. C. Over half of the eggs were collected at water velocities ranging from 100 to 119.9 cm/second; an additional 22% were collected at 60-79.9 cm/second.
