摘要
洪堡洋流系统支撑着世界上最大的中上层渔业,同时也是受到气候胁迫最为显著的海洋东边界流系统。本文概述了洪堡洋流系统的海况和渔业现状,围绕秘鲁鳀(Engraulis ringens)、智利竹■鱼(Trachurus murphyi)、远东拟沙丁鱼(Sardinops melanosticta)和茎柔鱼(Dosidicus gigas)4种代表性的重要经济渔业物种,总结气候和海洋环境对其生长繁殖、种群结构以及资源波动等影响。研究认为,以上4类中上层关键经济种类的物种丰度和分布均受到季节性、年际和年代际气候变化和洪堡洋流海洋条件的强烈影响,在未来气候变化的影响下,研究洪堡洋流生态系统需要依赖于高能力的综合生态系统模型,需考虑物理、生物和化学环境、营养结构等因素,全面地评估生态系统内各种群的变动规律,进而更加科学地开发和管理该系统的渔业资源。
The Humboldt Current System(HCS) supports the largest pelagic fisheries in the world, and is also strongly affected by climate forces in the Eastern Boundary Currents System. In this study, the sea conditions of the HCS and status of its fishery were summarized, then the effects of marine environment and climate changes on growth and reproduction, population structure and resource fluctuation of four representative fishery species, Peruvian anchovy(Engraulis ringens), Chilean jack mackerel(Trachurus murphyi), Pacific sardine(Sardinops melanosticta) and Jumbo flying squid(Dosidicus gigas) were further discussed. This study suggested that the species abundance and distribution of the above four pelagic economic species are strongly influenced by seasonal, interannual and interdecadal climate changes and oceanic conditions of the HCS. Furthermore, research on the Humboldt current ecosystem(HCES) under the influence of future climate change is expected to be highly dependent on high-capacity comprehensive ecosystem models, considering physical environment, biochemical reaction, nutritional structure and other factors. Based on the models and their evaluations, a thorough understanding of the variations of various kinds of population in the HCES will facilitate a more reasonable development and scientific management of the fishery resources within such system.
