STOCKING

Augmentation of wild populations with hatchery releases began soon after the first major declines in Atlantic salmon in the 1870s. It is convenient to divide Maine’s stocking history into three phases: historical (1871 to 1970); recent (1970 to 1992); and contemporary (1992 to present) (Figure 4). Details can be found in Baum (1997) and the report of the Biological Review Team (1999).

Historical Period (1871–1970)

This period began with the release of parr from Ontario into the Sheepscot River (probably from Lake Ontario1). As the import cost was high, a hatchery

The Atlantic salmon in Lake Ontario, extirpated by about 1900, might have consisted of two runs, those that remained in the lake (landlocked) and those that went to the ocean (anadromous). They might have spawned in the same or different
