大型水母的研究现状及展望

自20世纪90年代中后期起,东海北部及黄海海域发生大型水母连年暴发的现象,海域生态严重恶化,引起政府及研究部门的关注。本文综述了大型水母暴发对我国海洋渔业的影响,并列举了大型水母暴发的成因;对国内外大型水母生活史的研究现状进行了概述。建议模拟海洋环境即在各种环境因子不断变化的条件下,对大型水母的生活史进行进一步探讨研究。温度及饵料丰度对大型水母生长发育各阶段影响的研究可以补充完善沙海蜇的暴发机理。

Review on the current situation of macro-jellyfish research and expectations

Since the middle and the late of 1990s,the breakout of macro-jellyfish resulted in ecological degradation has been happened for years running in the Yellow Sea and the northern part of the East China Sea.So the causes and mechanism of macro-jellyfish breakout have been focused by the government and research organizations.The present paper summarizes the mechanism of macro-jellyfish breakout,its effects on the marine fisheries and the current studies on the life cycle of the macro-jellyfish at home and abroad.This article also advises some future works,the effect mechanism of environmental factors on life cycle of macro-jellyfish remains to be explored and the studies on how the diet abundance and temperature influence the growth of macro-jellyfish in the different stages are in need of being perfected in the future.
