Occurrence,viability and significance of resting eggs of the calanoid copepod Labidocera aestiva

Field and laboratory observations on the occurrence and viability of eggs of Labidocera aestiva Wheeler show that eggs of this temperate species which are laid in late fall remain viable on the bottom and hatch in late spring. These eggs thereby provide the means of repopulating temperate areas with this species after its winter disappearance from the plankton.
