Status of Atlantic salmon (Salmo salar L.) in Gander River, Notre Dame Bay (SFA 4), Newfoundland, 1989-1991 / by M.F. O'Connell and E.G.M. Ash. : Fs70-8/92-25E-PDF

The status of Atlantic salmon in Gander River in 1989-91 was determined using complete counts obtained from a counting fence located on the main stem just above head of tide, recreational fishery data, and biological characteristic data. The percentage of target spawning requirement achieved ranged from 33% (1991) to 36% (1990). There is evidence to suggest that declining catch per unit of effort in the recreational fishery in Gander River during 1979-89 was due in part to an increase in exploitation in the commercial fishery in the Gander Bay area. Low escapements since 1989 could also have been due to possible juvenile mortality resulting from unusually low flows in Gander River in 1987 and 1988 and to decreased marine survival"--Abstract, page 2.
