Young Chinook Salmon {Oncorhynchus tshawytscha) captured in the St. Lawrence River, near Cornwall (NMC 95-002; mm). was observed in the St. Lawrence River, 30 km upstream from Montreal (Dumont et al. 1988) but no evidence of successful reproduction (survival of young) was reported. This is, therefore, the first doc- umented record of Chinook Salmon natural repro- duction in the St. Lawrence River and the eastern- most of successful natural reproduction for this species in the Great Lakes-St. Lawrence System.

Acknowledgments These specimens were captured during a fish sur- vey done in the St. Lawrence River, near Cornwall, as part of a large multidisciplinary project funded by a tri-council grant dealing with Ecosystem Recovery on the St. Lawrence, obtained and administered by the Institute for Research on Environment and Economy at the University of Ottawa. Both speci- mens were deposited in the fish collection of the Canadian Museum of Nature (NMC 95-002 ( mm specimen), NMC 95-003 (42 mm speci- men). Lara L. Ridgway, Lee Willard, Martin D. Lemay and David Bajumy participated in the field- work. Courtaulds Fibres Canada allowed us to live in one of their cottages while working in Cornwall. The St. Lawrence River Institute of Environmental Sciences (Cornwall) provided us with logistical help during the field season. Erling Holm (Royal Ontario Museum) confirmed the identification of one (NMC 95-002) specimen. Our most sincere thanks to all the above-mentioned people and institutions for their help.
