The number of ova produced by American shad (Alosa sapidissima) based on samples of five fish from each of six Atlantic coast rivers was found to range from 209,000 to 616,000 ova per year. Hudson River shad produced fewer ova by size and St. Johns River shad produced more ova by size than did shad from the other four rivers. Statistical evidence is presented to show that the six ovarian samples per fish used to estimate total ova production can be reduced without imparing the accuracy of the total ova production estimate.
