Science Response 2013/009

Atlantic Salmon (Salmo salar) returns to the Miramichi River (NB) for 2012

Context

Atlantic Salmon for Gulf Region stocks are scheduled to be formally assessed every two years. The most recent assessment of the Atlantic salmon stock of the Miramichi River was prepared for the 2011 return year (DFO 2012). This science response report provides an update of the returns of Atlantic salmon to the Miramichi River for the 2012 return year. The report is the result of the Science Special Response Process of February 7, 2013. The returns of large salmon (>= 63 cm, fork length) to the Miramichi River in 2012 were estimated to be 13,630 fish (median value; 95% credibility interval 9,932 to 19,430). Small salmon (< 63 cm fork length) returns were estimated to be 8,010 fish (median value, 95% credibility interval 5,964 to 11,340). The low returns of large and small salmon in 2012 follow on the high returns of both size groups in 2011.
