中文摘要：

本研究应用汞质量平衡模型评估了黄海南部银鲳的日摄食量，为5．87gwet／100gwet／d。结合1998-2000年海上声学评估获得的资源量，计算了黄海南部银鲳年饵料消耗量为4．78×10^5t，食物转换效率为1．46％。根据观察食道侧囊和分析胃含物，确认水母是银鲳的食物源之一，食道侧囊能够高效碾磨水母，是银鲳重要消化器官，胃内鳞片不是银鲳摄食对象。亟需对银鲳摄食水母的生态过程进行深入研究，从而确定银鲳控制水母暴发的潜在可能性。

英文摘要：

In this study, daily food consumption by silver pomfret in the southern waters of the Yellow Sea evaluated by means of the Mercury Mass Balance Model （MMBM） was about 5.87 g wet/100 g wet/d. Based on its biomass estimated through four acoustic survey cruises, the annual food consumption of this stock in the southern waters of the Yellow Sea during 1998 -2000 was about 4.78×10^5t, and the conversion efficiency was 1.46%. Esophageal sac obser- vation and stomach content analysis revealed that jellyfish was one kind of food sources of silver pomfret. Esophageal sac was essential digestive organ to mill jellyfish, and scales in stomach were not feeding objects. It is suggested that, in order to elucidate whether jellyfish bloom could be controlled by increasing silver pomfret abundance, further research on the characteris- tics of feeding process of silver pomfret on jellyfish is needed.
