Morone chrysops Female Absolute fecundity Several papers described the fecundity of white bass. Ova counts ranged from 650,000 to 970,000 for three fish of unknown size from Spirit Lake, Iowa. Fecundity for 14 fish, 254 to 391 mm fork length from Shafer Lake, Indiana, ranged between 242,000 and 932,000 ova. Calculated fecundity for fish 320, 350 and 360 mm total length in Beaver Lake, Arkansas, was 360 000, 585,000 and 600,000 ova more than 0.57 mm in diameter respectively 650.0 thousand eggs
