Figure 2. North American distribution of the Chain Pickerel, Esox niger. reported in Queens and Halifax counties (Bob Bancroft, Wildlife Resources, Nova Scotia Department of Natural Resources). The species was introduced into New Brunswick (Cox 1896a,b) sometime in the 1800s. Cox (1896a) states that it was introduced into the St. John and St. Croix rivers, sometime after 1852 since the species had not been listed by Perly (1852). Scott and Crossman (1959) suggested that the first occurrence may have followed introductions into the St. Croix River in Maine about 1863. By 1970, Chain Pickerel were widely distributed in southern New Brunswick (Scott and Crossman 1959; Gorham 1970) being found in the lower St. John and St. Croix Rivers, and in the waters of Charlotte, Queens, Kings, Sunbury, and York counties, particularly in the St. John and Oromocto Rivers (New Brunswick Museum fish col- lection records, St. John, New Brunswick). Today it is more widespread and may be found almost any- where suitable habitat exists (M. Sullivan, Fish and Wildlife Branch, New Brunswick Department of Natural Resources, Fredericton, New Brunswick; personal communication). In Quebec, Chain Pickerel are found in the water- ways of th
