Survival of Atlantic salmon Salmo salar between fertilization and emergence was monitored in Northern Stream, Washington County, Maine. Green eggs were buried in modified Whitlock–Vibert egg boxes and survival was estimated on five occasions–four before emergence and one at emergence. Survival was 74% through hatching, but decreased rapidly after hatching to only 2% at emergence.
