中文摘要:
      为了解人工鱼礁投放对鱼卵和仔稚鱼分布的影响,于2018年1月(冬季)、4月(春季)、7月(夏季)和10月(秋季)利用大型浮游生物网在马鞍列岛海洋牧场开展了4个航次的水平拖网调查。根据鱼卵、仔稚鱼的种类组成、数量分布等群落结构特征,对投礁区和未投礁区鱼卵、仔稚鱼的资源分布进行研究。结果显示,2018年在马鞍列岛海洋牧场共采集鱼卵5 642粒、仔稚鱼1 013尾,隶属于10目21科49种。鱼卵优势种为龙头鱼、短吻红舌鳎和小黄鱼;仔稚鱼的优势种为褐菖鲉、花鲈和小公鱼属未定种。投礁区和未投礁区鱼卵仔稚鱼的优势种种类组成基本一致,但是群落结构差异显著,投礁区各个季节的多样性指数、丰富度指数及均匀度指数均高于未投礁区,与未投礁区差异显著,且春季投礁区的生物多样性最高。聚类分析显示,春季鱼卵、仔稚鱼群落结构最为稳定,冬季群落结构最简单,夏、秋两季相似度较高,群落结构更复杂。研究表明,马鞍列岛海洋牧场人工鱼礁的投放对鱼卵、仔稚鱼具有一定的聚集和庇护作用,温度(T)、盐度(S)、水体浑浊度(Turb.)等海洋物理环境因子对鱼卵、仔稚鱼分布影响显著。
英文摘要:
      With the aim of understanding the impact of artificial reef deployment on the distribution of fish eggs and larvae, a horizontal trawl survey using large plankton nets in Ma'an Archipelago from January 2018 to October 2018 was carried out on four voyages. According to the species composition, quantity distribution and other community structure characteristics of fish eggs and larvae, their resource distribution in reef areas and natural areas were studied.The results showed that a total of 5 642 fish eggs and 1 013 larvae were collected, which belonged to 10 orders, 21 families and 49 species. Harpodonle sueur, Cynoglossus joyneri and Larimichthys polyactis were dominant fish eggs; Sebastiscus marmoratus, Lateolabrax japonicus and Stolephorus sp. were the dominant fish larvae. The dominant species of fish eggs and larvae in the reef area and the natural area were almost the same, while the community structure was significantly different. The reef areas had significant differences with the natural areas in the biodiversity, and the diversity index, richness index and evenness index of the reef area were highest in spring. Cluster analysis indicated that the community structure of fish eggs and larvae were the most stable in spring, the simplest in winter, and the summer had the higher similarity with autumn. Comprehensive analysis suggested that artificial reefs in Ma'an Archipelago have certain aggregation and shelter effects on fish eggs and larvae, and the marine physical environmental factors such as temperature (T), salinity (S), water turbidity (Turb.) and so on have significant effects on the distribution of fish eggs and larvae.
