We evaluated storage of embryonated eggs of the signal crayfish Pacifastacus leniusculus in polystyrene boxes for 1, 3, 6, 28, and 56 d at two temperatures, 12 ± 1°C and 4 ± 0.5°C. For periods up to 4 weeks, survival at the end of storage for both temperatures exceeded 95%, and survival to stage‐2 juvenile (after first molt) exceeded 63%. Following 8 weeks of storage, survival to stage‐1 and stage‐2 juveniles was significantly reduced. These experiments have shown the feasibility of egg storage for up to 4 weeks. In addition, 6‐h transport (300 km) of embryonated eggs followed by up to 2 d of storage did not have a negative effect on egg viability.
