Assessments of Atlantic salmon stocks in southwest New Brunswick, 1999 [electronic resource] / T.L. Marshall, R.A. Jones and L. Anderson. Ottawa : Fisheries and Oceans Canada, 2000. 28, [1] p. : fig., graphs, maps, tables. Canadian Stock Assessment Secretariat research document, 1480-4883 ; 2000/010 Includes bibliographical references (p. 28). Assessed stocks of Atlantic salmon in southwest New Brunswick did not meet conservation requirements in 1999 and probabilities of achieving requirements in 2000 are virtually zero. Egg depositions for the Saint John River stock upriver of Mactaquac rose to 31% of the conservation requirement, and wild salmon continued to be at record lows. The Nashwaak River stock achieved only 19% of its requirement. Stocks of the Kennebecasis and Hammond rivers are unlikely to have met conservation requirements. Stocks of outer Bay of Fundy rivers west of the Saint John River system have declined markedly in the last decade and action is required to prevent their extirpation. In spite of long-standing restrictive fisheries management measures on salmon in distant and home-water areas, returns have fallen short of conservation requirements and expectations. These low returns have been associated with low marine survival. Other constraints include hydroelectric dams, artificial flow regimes, headponds, predators, and potential transmission of diseases and genetic swamping from nearby aquaculture facilities. gccst Fisheries resources gccst Salt water fish gccst Fishing area gccst Fisheries management Canada.
