This note reports the histological studies of gonad of the mullet. The fishes werecollected from the Huanghua and the Beitang of Cyclic changes of the gonads in mulletwere studied in the adu1t and young fishes. Qil globule formation in the oocytes began at stage Ⅱ to Ⅲ of gonad development(usually at the end of stage Ⅱ). When the oil globules fromed a ring in the periphery ofthe nucleus, the gonads entered stage Ⅲ. The oil globules extended from center to outerregion and combined with each other, at last there was only one golden oil globule in theegg. There is no vesicle in the mullet. Yolk formation in the oocytes begen in the winter. The volume of the ovary andthe size of eggs attained a maximum at the end of April or at the beginning of May. 相似文献
