摘要
中层鱼是指栖息于大陆斜坡和大洋中层(200~1000m)的小型鱼类,广泛分布于世界各海域,资源量极高,具有重要的生态地位。昼夜垂直迁移行为(diel vertical migration,DVM)是中层鱼最显著的生态特征之一。中层鱼通过垂直迁移过程中的代谢作用将海洋上层的生物碳向深海输送,为深海生态系统提供关键碳源,对海洋固碳和地球碳循环有重要意义。中层鱼昼夜垂直迁移研究已有50余年历史,但国内研究尚处于起步阶段。本文综述了国内外对中层鱼昼夜垂直迁移的研究进展,总结了中层鱼迁移机制及其对海洋碳循环的作用,以期提高我国对中层鱼资源的重视程度,为我国中层鱼及中上层海洋生态系统的研究提供参考。
Mesopelagic fish species are small in size,which inhabit the mid-waters of continental slopes and open ocean(200~1000 m).They widely distribute in oceans with abundant standing biomass and important ecological functions.Diel vertical migration(DVM)behavior is one of the most pronounce ecological features of these fish species.Mesopelagic fish species transport biological carbon from the epipelagic zone to the deep sea through metabolism during DVM,providing a key carbon source for deep-sea ecosystems.Such process is important for ocean carbon sequestration and carbon cycle of the earth.Studies on the DVM of these fishe species have lasted for over 50 years;however,the studies carried in China are at their infancy.In this review,we summarized the recent progress in the investigation of DVM of mesopelagic fish species at home and abroad,and introduced the results of the investigations on the mechanism of vertical migration of the mesopelagic fish species and their roles in the ocean carbon cycle.We aim to emphasize the importance of mesopelagic fish resources and provide information for the studied on the mesopelagic fish species and mesopelagic ecosystem in China.
