dc.description.abstractThe 1984 Atlantic salmon (Salmo salar) run on the Magaguadavic River, New Brunswick, monitored at the St. George fishway numbered 767 fish (512 multi-sea-winter salmon and 255 grilse). The alewife run was estimated at 43,720 +/- 8665 fish within 95% confidence limits. Biological data for the 1984 and 1985 alewife spawning runs are presented. Timing of runs of alewives and salmon passing through the fishway was similar to 1983 and could serve as a guideline to schedule fishway maintenance. Observations on fish use of a newly installed downstream bypass sluice and predation by gulls are also presented. Cannibalism of emigrating juvenile alewives by subadults in the estuary was considered a major source of mortality.
