Fecundity relationships of 156 female herring (Clupea harengus pallasi) from Prince William Sound were studied. Upon comparison with other North American populations of Pacific herring, we found a progressive decrease in fecundity at a particular body size with increasing latitude. We also found an increase in mean length and mean fecundity of spawner with latitude.
