Egg-to-fry survival of two strains of Atlantic salmon (Salamo salar) in stream incubators under laboratory conditions

摘要

Egg-to-fry survival of two strains of Atlantic salmon (Salmo salar) was evaluated under laboratory conditions in two commercial stream egg incubators. The survival was also examined based on egg developmental stage (i.e., green eggs, eyed eggs, advanced eggs). There was no significant difference in survival of eggs in the Jordan-Scotty and Whitlock-Vibert incubators. However, the survival of Sebago strain Atlantic salmon eggs was significantly higher than that of Penobscot stream eggs, and survival increased with advanced egg developmental stage.
