Status of Atlantic salmon (Salmo salar L.) in Gander River, Notre Dame Bay (SFA 4), Newfoundland, 1995
By M.F. O'Connell; D.G. Reddin; E.G.M. Ash
Abstract
The status of Atlantic salmon in Gander River in 1995 was determined using counts of small and large salmon from a counting fence located on the main stem just above head-of-tide, recreational fishery data, and biological characteristics information. The assessment was conducted in relation to the five-year moratorium on the commercial Atlantic salmon fishery, which entered its fourth year in 1995. The proportion of target egg deposition requirement achieved in 1995 was 93% which compares to 112% in 1992, 135% in 1993, 89% in 1994, and 33%-36% for the period 1989-91. Number of small salmon spawning during 1989-91 were the lowest recorded since 1974. There was a significant decline in estimated total population sizes of small salmon during the period 194-95. Recruitment during 1989-95 was among the lowest in the time series. The number of recruits per spawner for 1995 was the highest since 1988, probably the result of increased sea survival . Anticipated returns of small salmon in 1996 will be below target requirement, without a recreational fishery. For the period June 17 - July 5, of the small and large salmon examined, 16.9% and 46.1% possessed net marks.
