摘要: 为了解西北太平洋亚热带海域浮游动物群落结构,根据2019年3月“淞航号”调查船在西北太平洋(28°—35° N,147°—154° E)44个站点进行渔业资源调查期间采集的浮游动物样本,分析了浮游动物的种类组成与分布。结果表明: 该海域共鉴定出浮游动物456种(含浮游幼体和未定种),属于14个类群8个门类,其中桡足类163种,为最优势类群。优势种包括9种暖水种: 螺旋尖角水母、瘦新哲水蚤、瘦乳点水蚤、肥胖箭虫、邦海樽、六鳍箭虫、喙真胖水蚤、小哲水蚤、细角间哲水蚤,以及1种温带种捷氏哲水蚤。暖流指示种六鳍箭虫和寒流指示种捷氏哲水蚤均是优势种并同时出现在亚热带海域,表明亲潮和黑潮对该海域浮游动物的多样性和时空分布具有重要影响。各站点平均生物量为(31.64±23.81) mg·m-3,平均丰度为(22.2±17.6) ind·m-3。单纯度指数(C)、均匀度指数(J)、Shannon多样性指数(H)、丰富度指数(D)均值分别为0.09±0.10、0.76±0.10、4.88±0.71、23.53±8.08。4种指数空间分布不均匀,呈现斑块状。研究期间,西北太平洋浮游动物种类组成丰富,物种分布不均匀,群落结构稳定。

Abstract: Based on the investigation data of 44 stations in the area 28°-35° N, 147°-154° E of the Northwestern Pacific Ocean by the research ship ‘Songhang' in March 2019, we analyzed species composition and distribution of zooplankton to understand zooplankton community structure in the subtropical areas of the Northwestern Pacific Ocean. The results showed that a total of 456 zooplankton species (including planktonic larvae and unidentified species) were recorded in the surveyed area, which were belonged to 8 categories and 14 groups. There were 163 species of copepods, as the dominant group. The dominant species included 9 warm-water species, Eudoxoides spiralis, Neocalanus gracilis, Pleuromamma gracilis, Sagitta enflata, Doliolum nationalis, S. hexaptera, Euchirella rostrata, Nannocalanus minor and Mesocalanus tenuicornis, and one temperate species, Calanus jashnovi. Both the warm current indicator species S. hexaptera and the cold current indicator species C. jashnovi occurred simultaneously in the subtropical area, indicating that the Kuroshio Current and the Oyashio Current had an important impact on the diversity and temporal-spatial distribution of marine zooplankton. The average biomass was (31.64±23.81) mg·m-3, and the average abundance was (22.2±17.6) ind·m-3. The average values of purity index (C), eveness index (J), Shannon diversity index (H) and richness index (D) were 0.09±0.10, 0.76±0.10, 4.88±0.71, and 23.53±8.08, respectively. The spatial distribution of the four indices were uneven and irregular. During the study period, species composition of zooplankton in the Northwest Pacific was rich, species distribution was uneven, and community structure was stable.
