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。
The sexual maturity of Yellow Carassius auratus in the southern Bohai Sea was mid- and late-July-mid-mid-July, and peaked in June and mid-June. The sexual maturity of Yellow Carassius auratus in Bohai Bay was about 10 days later than that of Laizhou Bay. The population is mainly distributed in the northwest of Laizhou Bay and the southern part of Bohai Bay, followed by the western Bohai Bay. The northern Bohai Bay and the southern part of Laizhou Bay are not yellow carp spawning grounds. The distribution of temperature and salinity ranged from 15-27.1 ℃ and 28.98-32.14 respectively in mature individuals of Carassius auratus, belonging to broad-sparsely-salty salt. The distribution of quantity and temperature and salinity were closely related to each other.
