Status of Atlantic salmon (Salmo salar L.) in Trout River (SFA 14A), Gros Morne National Park of Canada, Newfoundland, 2001
By Hugh McCormack, Thomas W. Knight, and Todd Gallant
Abstract
During the period June - August, 2001, a fish counting fence was established for the first time on the lower part of Trout River, Newfoundland, in Salmon Fishing Area (SFA) 14A. Approximately 55 % of the watershed is located within the boundaries of Gros Morne National Park of Canada. The remaining 45 % of the watershed is located east of the Park's south-east boundary in Provincial Forest Management Area 15. A total of 51 adult anadromous Atlantic salmon (Salmo salar) (consisting of 15 large [> 63 cm fork length] and 36 small [<63 cm fork length] fish) returned to the river during the period of operation. Data from Trout River were not available to determine the values of several variables important in the calculation of egg deposition. In these cases data from other rivers in SFA 14A were substituted to provide a range of potential egg deposition values. Assuming that these substituted values are consistent with those from Trout River, adult salmon runs to the watershed fall significantly short of Department of Fisheries and Oceans conservation requirements. Preliminary investigations into the status of the exotic species rainbow trout (Oncorhynchus mykiss) were conducted in conjunction with this study.
