Status of Atlantic salmon in Conne River, SFA 11, Newfoundland, 1998.
By J.B. Dempson, G. Furey and M. Bloom
Abstract
Results obtained from a fish counting fence provided the basis for the assessment of the Conne River Atlantic salmon stock in 1998. Returns to home waters (river and estuary) were 2931 salmon < 63 cm in length and 295 salmon ³ 63 cm in size. This represented a decrease of 8% for small salmon in comparison with 1997 while large salmon returns increased by 59% to the highest level since 1990. Sea survival to 1SW salmon fell to the lowest level recorded (2.46%). Only 83% of the Management Target was met but 150% of the conservation egg requirement was attained. A mark-recapture study estimated a smolt run in 1998 of approximately 70,000, which was 31% lower than 1997 but 6% higher than the average from 1987 - 1995. Based upon an increase in egg-to-smolt survival coincident with decreasing egg deposition rates per unit of fluvial habitat, a review of the current Management Target of 7.8 million eggs may be warranted. Information on the occurrence of escaped farmed rainbow (steelhead) trout in Conne River, and results of angling activity for escaped rainbow trout during the winter of 1999 are also provided.
