| Abstract: | This paper deals with the regular the development patterns of gonad and the reproductive cycles of Gomphina veneriformis (Lamarck). According to the cytological characteristics of the developing sexual cell and the change of the precentage of drain body weight and the precentage of fresh body weight in different developing periods, the development of gonad can be divided into five stages: (1) proliferation period, (2) growth period, (3) maturation period, (4) spawning period and (5) resting period.There is one annual spavoring peak in the Zhoushun sea area, from the last ten days of August to the middle ten days of September. Some early-maturing males were found. |
