摘　　要：早期补充群体的生长及其存活率决定了群体资源数量和群体结构特征。为深入了解鱚属(Sillago)鱼类鱼卵的补充机制,本文根据2014—2018年5—8月黄海中南部海域(33°00′N—36°00′N,119°00′E—122°00′E)的鱼卵调查数据,利用Tweedie分布的广义可加模型(GAM),研究了黄海中南部鱚属鱼类鱼卵的时空分布及其与环境因子的关系。研究表明:影响鱚属鱼类鱼卵分布的因素有经纬度、月份、流速、海水表层盐度、海水表层温度,偏差解释率分别为29.20%、15.30%、1.10%、0.40%和1.20%。鱚属鱼类鱼卵主要分布在海州湾海域(34°00′N—36°00′N,119°00′E—121°00′E)。产卵期为6月中旬至8月上旬,7月上旬鱼卵数达到峰值。鱚属鱼类鱼卵的适宜分布区为流速较小的区域,在流速0.12~0.16 m/s范围内的区域鱼卵数较多。鱼卵丰度随着海水表层盐度的升高而降低,随着海水表层温度的增长呈波动趋势,其海水表层最适盐度为28~33、海水表层最适温度为23~27℃。本文揭示了鱚属鱼类鱼卵的时空分布特征及其与环境因子的关系,可为鱚属鱼类资源的合理利用提供基础资料。Population size and structure are determined by the growth and survival rate of early recruitment. In order to understand the early recruitment mechanism of Sillago species, we analyzed the spatio-temporal distribution of Sillago species eggs and their relationship with environmental factors using the generalized additive model(GAM) with Tweedie distribution. The study was based on the survey data of fish eggs in the central and southern Yellow Sea(31°00′N—36°00′N, 119°00′E—123°00′E) from May to August in 2014—2018. Results showed that the longitude and latitude, month, velocity, sea surface salinity and sea surface temperature were the main factors affecting the distribution of Sillago species eggs with deviance explanation rates of 29. 20%, 15. 30%, 1.10%, 0.40% and 1.20%, respectively. Sillago species eggs were mainly distributed in Haizhou Bay(34°00′N—36°00′N, 119°00′E—121°00′E). The spawning period was from the middle of June to the early August, and the number of eggs reached the peak in the first ten days of early July. Sillago species eggs were mainly concentrated in areas with low velocity and velocity of 0.12~0.16 m/s. The abundance of fish eggs decreased with increasing salinity and fluctuated with increasing temperature. The optimal range of sea surface salinity and sea surface temperature were 28~33 and 18~27 ℃. This research revealed spatiotemporal distribution characteristics of Sillago species eggs and their relationship with environmental factors, which provided the foundation for the exploitation and management of Sillago species resources.
