Yolk formation is initiated by the accumulation of mitochondria in the perinuclear region of Calanus finmarchicus and Epilabidocera amphitrites and the yolk granules are formed in close association with the mitochondria. Biades-Eckelbarger and Youngbluth (1984), however, found no evidence of implication of mitochondria in yolk formation in Labidocera aestiva. The ripe oocytes in the oviducts are covered by a very thin membrane, the perivitelline membrane. The process of fertilization is not clear (Park, 1966).
