Presents a study of the fork length, sex, and age of adult Atlantic salmon returning to the Nepisiguit River, New Brunswick. The study was conducted to determine whether those biological characteristics varied between fish of known hatchery origin (marked by a clipped fin) and presumed wild fish. Trends over time between 1982 and 1996 were also examined. Comparison is also made between the characteristics of Nepisiguit River salmon with those of the Miramichi and Restigouche rivers.
Reports assessments of Buctouche River (south-east New Brunswick) Atlantic salmon stock, as determined through mark-recapture experiments in which tags were applied in the estuary and recovered in the recreational fishery or at a counting fence upriver. Results of electroseining at ten sites during summer 1998 are included in the assessment, along with juvenile density data from previous years, for purposes of comparison. Information on biological characteristics such as length is also provided.
Emphasis is placed on characteristics of salmon from the Northwest Miramichi in support of a review of the risks to long-term fitness of wild Atlantic salmon of a proposed supplementation program consisting of the captive-rearing in freshwater of wild salmon smolts to the adult stage and release back to the river to spawn. [...] Freshwater dynamics of Atlantic salmon are examined to assist in the evaluation of the risks and /or benefits of the proposed supplementation activity in achieving one of the stated goals which is to increase abundance of adult Atlantic salmon to the river. [...] Emphasis is placed on characteristics of salmon from the Northwest Miramichi in support of a review of the risks to long-term fitness of wild Atlantic salmon of a proposed supplementation program consisting of the captive-rearing in freshwater of wild salmon smolts to the adult stage and release back to the river to spawn (DFO 2016). [...] The two main branches of the Miramichi River are each comprised of two main rivers which join near the head of tide; the Renous and Southwest Miramichi rivers join at the head of tide in the Southwest Branch of the Miramichi, the Little Southwest and Northwest Miramichi rivers join at the head of tide in the Northwest branch of the Miramichi (Fig. [...] There was no statistically significant association between the proportion of the early tagged salmon which ascended to the facilities prior to September 1 and neither the elevation nor the distance of the facility from the head of tide (Fig.
