| 摘 要： | 渤海南部黄鲫的性成熟期为5月中、下旬—7月中、下旬，盛期为6月上、中旬，其中渤海湾黄鲫的性成熟期比莱州湾晚10天左右。群体主要分布于莱州湾西北部和渤海湾南部，其次是渤海湾西部海域，渤海湾北部和莱州湾南部不是黄鲫产卵场。黄鲫性成熟个体分布的温、盐度范围分别为15－27．1℃和28．98－32．14，属广温狭盐性，数量分布与温、盐度有密切相关关系。

| Abstract: | It is found that the period of zunasi's sexual maturity in the southern Bohai Sea is from the middle of May to late July, and the best time is in the former twenty days of June. The zunasi in Bohai Bay are ten days later than those in Laizhon Bay in reaching sexual maturity. Its colony is mainly distributed in the north-west of Laizhou Bay and the south of Bohai Bay, the next is the west of the Bohai Sea. The north of Bohai Bay and the south of Laizhou Bay are not its spawn ground. The salinity temperature and for sexually mature individuals are 15.0-27.10 and 28 98-32 14 respectively. The distribution of zunasi is closely related to temperature and salinity. |
