Abstract
A study of the American shad fishery of the York River Va. during 1959 showed an estimated total catch of 463,000 pounds, a fishing rate of 55.2 percent, and a total population of 839,000 pounds. Additional estimates of catch and effort were used to calculate fishing rate and population size for each year 1953 through 1958. Analyses of scales showed that most shad spawn at 3, 4, and 5 years of age and approximately, 23 percent of the fish caught during the 1957-59 seasons had spawned the previous year. The number of ova produced by. York River shad ranged from 169,000 to 436,000 per fish.
