North includes fish from Jersey City, Raritan Bay, and Sandy Hook. Central includes fish caught between Point Pleasant and Atlantic City. South includes all locations south of Atlantic City. Given are arithmetic means±SE (geometric means below) with Kruskal–Wallis χ2 values and p values. Duncan values are given in parenthesis. Note: 89% of the bluefish from the South were caught in trawls or seines, probably accounting for the smaller size.
