And this: Kohlenstein
(1981) showed that approximately 50% of the 3-year-old female striped bass in Chesapeake Bay, and a smaller percentage of 2- and 4-year-old females, moved to the coast to join the migration annually. In contrast, few males of that age were migratory."

Yeah, I came across the "may forego" too, but there wasn't an explanation or source. It probably comes from that Kohlenstein paper, which I think was the one that lead to the assumption that males stayed in the bay. That is the right time frame. My recollection, and it's been probably 15 years since I actually read a lot of the related literature, was that they looked specifically at the young classes and it was extrapolated that males don't leave, but later studies determined that they just don't leave until they are older. I don't know if/what reasons were hypothesized, but my first guess would be linked to differences in time to mature between males and females. It is a critical consideration when evaluating benefits of a slot.
