渤海南部黄鲫幼鱼随水温上升，群体迅速向外海回游，遍及整个渤海湾及莱州湾西部；随水温下降，幼鱼又向近岸回游，活动范围缩小。７～９月黄鲫幼鱼适宜水温为２２．２～２９．０℃，盐度１２．９６～３３．３１。数量分布与温度间呈密切负相关，与盐度呈抛物线相关。
The juvenile yellow carp (Carassius auratus) in the southern Bohai Sea increased with the increase of water temperature, and the swiftly migrated to the outer sea all over the Bohai Bay and the west of Laizhou Bay. As the water temperature dropped, the juveniles returned to the nearshore and the range of activities narrowed. The suitable temperature of juvenile yellow carassius auratus from July to September was 22.2-29.0 ℃ and salinity 12.96-33.31. The quantity distribution is closely related to the temperature and parabolic with salinity.
