To augment the fish supply in New England increased attention is being accorded to the alewife. Through neglect, obstructions to migration, overfishing, and other causes, the alewife populations have been reduced greatly. A survey of the coastal streams of Maine disclosed many streams that can be returned to production by building fishways or modifying present fishways, in conjunction with a program of restocking and proper management methods. During the 1943 season, barren spawning areas (lakes) on 13 streams were stocked with alewives and observations indicated successful production and survival of young. Recommendations are made for the removal of obstructions or the construction of fishways on 17 streams.
