Recaptures of tagged Atlantic salmon (Salmo salar) released as smolts into the Big Salmon River varied between annual releases with no differences found on the basis of native or nonnative origin. Few were recaptured outside the Bay of Fundy. Distant fisheries in Greenland and Newfoundland take few salmon from Big Salmon River and commercial exploitation within the Bay of Fundy is minor, particularly by the former large fishery off the mouth of the Saint John River.

Adult Abundance

Stream discharge has long been associated with abundance of returning adult spawning salmonids to streams and may also affect body size distribution of adult salmon as low flows interfere with returns of larger-bodied fish. We examined these relationships of abundance and body size within Catamaran Brook, a third-order tributary to the Miramichi River system of New Brunswick, Canada, to investigate the causes of a declining trend in annual returns of Atlantic salmon (Salmo salar) to this stream. Regression models of adult abundance, proportion of the run as grilse, and body size of returning adults as functions of maximum daily stream discharge during the period of upstream spawner migration were constructed. Adult abundance shows a logarithmic relationship with stream discharge and provides good predictive ability, while appearing to not be significantly related to adult abundance in the larger Miramichi system. The proportion as grilse in the run and female body size are also logarithmically related to stream discharge, with low flow years being very influential in the regressions. These relationships of Atlantic salmon population abundance and body size characteristics have implications with respect to stock integrity and production of the following generation.

An unusual case of male predominance among Atlantic salmon (Salmo salar) repeat spawners was observed in the Saint John River, N.B., in 1967. A sample of 947 Saint John River salmon (416 grilse and 531 older salmon) contained 91 repeat spawners, 50 (55%) of which were males.
