FWS quotes a 1981 study by Mclaren, which I saw earlier today. The full paper wasn't available online, but what I could read of the original paper raised some questions to me about their conclusions so I dug around literature a bit. The 1981 paper seems to have been mostly dismissed since then. So yes, it is old and outdated info.
For example:
"Tagging studies performed between 1948 and 1952 concluded that theHudson River stock limited its movements outside the river to western Long Island (Raney et al. 1954). McLaren et
al. (1981), based on tagging done in 1976 and 1977 reported somewhat broader coastal movements, but only as far
northward as Newburyport, Massachusetts, and an absence of a relationship between fish length and distance from
the river. But tagging of striped bass conducted in the Hudson River between 1984 and 1988 showed an expansion
of range, with recoveries made northward as far as Maine and the Annapolis River, Nova Scotia (Waldman et al.
1990a). They also found a strong relationship between fish length and distance from the river, and interpreted
the
absence of such a relationship in the results of McLaren et al. (1981) as an artifact of size-dependent tag retention
(Waldman et al. 1990b). "
