Status of Atlantic salmon in the Restigouche River, 1986 / by R.G. Randall, G. Landry, A. Madden and R. Pickard. : Fs70-8/87-6E-PDF
"Catches at two estuarial traps and the Native fishery at Restigouche indicate salmon returned earlier to the Restigouche River in 1986 than in 1985. Angling catches of MSW salmon (in Québec) and 1SW salmon (Québec and New Brunswick) exceeded average catches of previous years, suggesting returns in 1986 were relatively high, particularly for 1SW salmon. Counts of MSW and 1SW salmon at Upsalquitch barrier were also greater than average (about 2x). Total returns were estimated to be 19,900 MSW and 11,000 1SW salmon, and spawning requirements were apparently met in 1986. The 1986 management plan, which restricted harvest of MSW spawners in homewaters, resulted in 75% of MSW salmon returns potentially surviving to spawn. Large average size for 1SW salmon in 1986 suggests growth conditions at sea were favourable, and high marine survival might explain the increased abundance of salmon in 1986. Returns in 1987 are forecasted to be 21,900 MSW salmon and 9,100 1SW salmon"--Abstract, page 2.
