Status of Atlantic salmon (Salmo salar L.) in Gander River, Notre Dame Bay (SFA 4), Newfoundland, 1998 / by M.F. O'Connell, A. Walsh and N.M. Cochrane. : Fs70-1/1999-86E-PDF
This paper examines the status of Atlantic salmon in Gander River in 1998, the seventh year of the commercial salmon fishery moratorium. Counts obtained from a counting fence are used in conjunction with recreational fishery data and biological characteristics data to calculate total river returns and egg deposition. Status of stock is evaluated against a conservation egg requirement derived for Gander River. Other information available in this document includes life-history characteristics of large salmon sampled in Gander River since 1978 and water temperature and water level data since 1989. The results of an examination of the impact of counting fence operations on the timing and availability of fish to anglers are presented. Arising out of the conclusions and recommendations of a workshop on possible causes of low returns of Atlantic salmon in 1997, a study examining predation on Atlantic salmon smolts by cod was conducted in Gander Bay in 1998, the results of which are presented herein.
