Abstract : In the United States, Atlantic salmon originally occurred in at least 28 rivers from the St. Croix in Maine to at least the Housitonic in Connecticut, and probably as far as the Hudson River in New York (Dunfield 1985). Estimates of historical populations range from 300.000 (USFWS 1984) to 1.1 million fish (Dunfield 1985). A combination of overharvest, lost access to spawning areas because of dams, and degraded water quality resulting from logging, agriculture, and municipal and industrial sewage caused a steep decline in populations from the late 1700s to the mid 1900s (Dunfield 1985. Stolte 1981). By about 1950 only a few hundred fish returned to five Maine rivers (USFWS 1984). Recovery of stocks began following passage of the Anadromous Fish Conservation Act in 1965. By the early 1980s returns reached 3,000 to 7,000 fish in 16 rivers, from the St. Croix in Maine to the Connecticut in Connecticut, Massachusetts, Vermont, and New Hampshire (Lewis 1991; Haines 1992).
