Juvenile Atlantic salmon of the Pigou and Bouleau Rivers, Quebec, were studied during the summer of 1972 and 1973. Growth increments for Pigou salmon averaged 36–50 mm yr−1 and smolts averaged 2.9 yrs old. Bouleau salmon grew slower (26–41 mm yr−1) and became smolts at a slightly older mean age (3.1 yrs). Mature male parr were more abundant in all age-groups from the Plgou River, possibly because of the faster growth. In terms of management, the Pigou River has little potential for increased salmon production because of limited habitat. On the other hand, the Bouleau River has considerable potential, and salmon production could be increased if the upper reaches were made accessible to migrating salmon.
