Abstract
Fecundities of primiparous and multiparous female Tanner crab (C. bairdi) from the eastern Bering Sea are compared. Primiparous females are .apprx. 70% as fecund as equal-sized multiparous females. Primiparous females molt and grow before extruding eggs; multiparous females do not grow. The lesser fecundity of primiparous females may be due either to the energetic cost of growth or to their having a smaller volume within the exoskeleton available for ovarian tissue at their premolt size.
