Abstract:
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.
