在浙江温岭沿海逐月采样，显微观察了可口革囊星虫体腔中卵细胞大小组成的周年变化。3-5月，卵径30～90μm的卵细胞占大部分。6月，卵径70～130μm的卵细胞占多数。7月，大部分卵细胞卵径达100μm以上，其中130～150μm的卵细胞约占1/3。8月，卵细胞卵径均在110μm以上，其中130～150μm的卵细胞约占2/3。9月，仍多数卵细胞卵径在110μm以上，130～150μm的卵细胞约占1/3。10月，以110～140μm的卵细胞占多，40μm以下的卵细胞较少，大卵细胞开始退化。11月至翌年2月，随着大型卵细胞的逐渐退化，小型及中型卵细胞逐渐增多，2月仍可见少量未退化的大型卵细胞。分析认为，可口革囊星虫在浙江温岭的繁殖期主要在7-9月。

The sexually mature Phascolosoma esculenta was sampled monthly along the Wenling coast of Zhejiang Province .Forty indi-viduals were dissected each time to observe the annual variation of oocyte size in the coelom of P.esculenta by microscopy .During one-year observation , the results showed that most oocytes were 30-90μm in diameter from March to May .And from June , most egg cells were about 70-130 μm in diameter.In July, August and September , the diameters of many oocytes exceeded 100 μm, 130μm-150μm, respectively;furthermore, the oocytes of 130μm-150 μm in diameter occupied a majority (1/3, 2/3 and 1/3, respectively) in those three months mentioned above .In October , the diameters of most oocytes ranged between 110μm and 140μm and big-sized eggs tended to degenerate .From November to February of the next year , as the big-sized eggs degeneration , small and medium-sized eggs gradually increased in number .However , some big-sized eggs without degeneration also could be found in small amounts in February . It could be included that the propagation season of P.esculenta was from July to September .
