Assessment of Atlantic salmon of the Saint John River, N.B., 1986 / by T.L. Marshall. : Fs70-8/87-55E-PDF
"Estimated total returns to the Saint John River in 1986 were 16,027 1SW and 11,839 MSW salmon. Homewater removals of about 4,000 1SW and 4,400 MSW fish led to an estimated 1986 spawning escapement only 73 percent of the target number of MSW spawners. The forecast of 1987 homewater returns is 13,152 1SW fish (5,552 more than the target escapement) and 18,003 MSW salmon (7,403 fish more than the target escapement plus hatchery broodstock requirements). Homing tendencies of the MSW salmon to 'above' and 'below' Mactaquac origins will result in surpluses to spawning requirements of 6,081 fish 'above' Mactaquac and 1,322 fish 'below' Mactaquac. Variation between forecasts and 'actual' fish returns suggest the utility and value of multi-year management plans based on general trends in stock status rather than on a specific assessment"--Abstract, page 2.
