<em>Abstract.</em>—The American eel <em>Anguilla rostrata </em>is an important component of the aquatic ecosystem of Lake Ontario and the upper St. Lawrence River and historically has been one of the most valuable commercial species in Ontario waters of this system. Between 1984 and 1993, reported annual harvest ranged from 104 to 124 metric tons. Since 1993, eel harvests have declined precipitously in all areas above the Moses-Saunders Power Dam in spite of an increase in price per kg. During 2002, fishers held 85 eel licenses and harvested 12 metric tons (mt) of maturing yellow eel, mostly with hoop nets and trap nets. The numbers of eels migrating into this system in recent years suggests that if fishing effort remains constant, commercial harvests in areas above the dam will be under 3 mt per year between now and 2010. Provincial management programs have imposed license and season restrictions, reduced quotas, and more detailed catch reporting. Sustainable management practices throughout the range of this panmictic species will be required to restore the eel as an abundant species in Lake Ontario and the upper St. Lawrence River.

The life history of eels in Lake Ontario was studied by measuring, tagging, and releasing about 1500 individuals between 1958 and 1966. The smallest eels captured were from 295 to 318 mm long. Presumably they entered the lake at about age III–IV at lengths of 200–300 mm. Otoliths of eels from the lake showed a range in age between IV and XVIII, while those of smaller eels from the Ottawa River ranged between age II and IX. The length–weight regressions showed two distinct growth phases: one from about 480 mm to 790 mm, the other from about 830 mm to 1080 mm. Growth of the orbital diameter, interorbital distance, and pectoral fin length in relation to total length was not obviously related to sexual maturity. Eels that emigrated from the lake had a greater weight–length ratio than those that remained in the lake for another year. Of 917 tagged eels transplanted within Lake Ontario, 28 were recaptured near and 18 recaptured far from the original capture site. Although the results are inconclusive, there is a suggestion that eels have home territories within the lake.
