进行了大面积试捕调查,研究了渤海南部黄鲫不同季节的回游分布及与水温、盐度的关系。5~9月,黄鲫的适温范围为9.2~29.6℃,最适温16~23℃,适盐范围23.5~32.14,最适盐度27.5~30.5,属广温狭盐性。在适温、适盐区间内,黄鲫数量分布与其均呈曲线相关关系。
A large-scale test-catch investigation was conducted to study the relationship between the return travel and the water temperature and salinity in different season of yellow carp in southern Bohai Sea. From May to September, the suitable temperature range of yellow carp was 9.2 ~ 29.6 ℃, the optimum temperature was 16 ~ 23 ℃, the suitable salt range was 23.5 ~ 32.14, and the optimum salinity was 27.5 ~ 30. 5, is a wide temperature salt. In the suitable temperature, suitable salt interval, yellow carp quantitative distribution and their curves were related.
