Coinciding with decreased returns to the Penobscot River there has been a reduction in the percentage of the run of repeat spawners from an average of 1.7% in the 1980s to an average of 0.6% in recent years (Maynard et al., 2017).

Although heterochronal spawners might not benefit from predator satiation as much as isochronal spawners, they do benefit from an increase in fecundity, a spread of predation risk, a spread of larval impact on their prey, and a decrease in the risk of spawning eggs in unfavorable conditions (12).

In addition, interannual differences in length-specific fecundity of the Norwegian spring spawning herring were explained by variation in weight-at-length, that is higher fecundity of spawners in better condition (Oskarsson et al., 2002).
