Here is a study which analyzes Striped Bass and American Shad spawning phenology in the Hudson River estuary.

As of the study's writing average spawning cessation and duration of both species were minimally affected with respect to historical averages.
However the study authors do make predictions in line with current climate models, and project an earlier spawn of about a week to two weeks for both species by the 2090s. However the authors also make many assumptions which are impossible to control for, but its a solid baseline projection.
However since the large majority of the biomass are Chesapeake fish which are more migratory, we may not be able to draw the same conclusions
