Egg deposition by Atlantic salmon, Salmo salar Linnaeus, at Cove Brook, Maine, in 1955 was estimated at 226 eggs per 100 square yards. In 1956, the estimated egg deposition was 293 per 100 square yards. Standing crops of young‐of‐the‐year averaged 20 per 100‐square‐yard unit in the summer of 1956 and 33 per unit in 1957. Yearlings numbered 26 to 34 per unit in 1956, 12 to 15 per unit in 1957, and 14 to 18 per unit in 1958. Known smolt production per year class averaged 3 migrants per 100 square yards. Survival of midsummer young‐of‐the‐year to the migrant smolt stage was estimated at not less than 5.3 percent. Survival of smolt to mature, returning adults may be as high as 3 percent.
