摘　　要：长岛毗邻水域是黄渤海鱼类洄游迁徙的生态廊道,是黄渤海鱼类连通的关键区域。基于2021年3-12月对长岛毗邻水域开展的鱼卵、仔稚鱼逐月调查,分析了长岛毗邻水域鱼类早期资源丰度时空格局、群落结构更替规律以及群落功能多样性时空差异。结果显示,共采集到36种鱼卵、仔稚鱼,其中,鱼卵和仔稚鱼种类数均为21种,鱼卵总数量为71 695粒,仔稚鱼总数量为1 161尾;主要产卵期为5-8月,主要种类为鳀(Engraulis japonicus)、黄姑鱼(Nibea albiflora)、长蛇鲻(Saurida elongata)、黑鲷(Acanthopagrus schlegelii)、少鳞[鱼喜](Sillagojaponica)、白姑鱼(Pennahia argentata)、绯[鱼銜](Callionymus beniteguri)、短吻红舌鳎(Cynoglossus joyneri)等,鱼卵密集区位于调查水域东部至西南部的庙岛海峡毗邻水域;仔稚鱼主要集中于5-7月和11-12月,主要种类为鳀、白氏银汉鱼(Hypoatherina valenciennei)、大泷六线鱼(Hexagrammos otakii)、玉筋鱼(Ammodytes personatus)等,仔稚鱼密集区位于调查水域东部、西南部和西北部;春夏季(5-7月)鱼类早期资源群落功能丰富度、均匀度和离散度指数最高,高值区主要分布在调查水域东北部和西南部。长岛毗邻水域鱼卵及仔稚鱼丰度、群落结构及功能具有明显的时空异质性,鱼类繁殖群体的洄游迁徙对长岛毗邻水域鱼类早期资源群落产生深刻影响。The waters adjacent to the Changdao Islands are a key gateway for fish recruitment and 0-year-old juveniles migrating between the Yellow and Bohai seas,and there is a lack of local observations of early life history characteristics of fish in this area.To investigate monthly variations in the abundance,community structure,and functional diversity of early life resources of fish in waters adjacent to the Changdao Islands,monthly surveys were conducted from March to December,2021.This study examined the spatiotemporal patterns of the early life resource abundance of fish in waters adjacent to the Changdao Islands using data on fish eggs,larvae,and the environment,and analyzed monthly variations in community structure and functional diversity.Spatial interpolation,Garrison centroid,and similarity percentage analysis methods were employed,along with functional trait indices.A total of 36 early life fish resource species comprising 21 separate species of fish eggs and larvae were collected from waters adjacent to the Changdao Islands between March and December 2021.The total quantity of fish eggs was 71,695,and that of larvae was 1,161.The main spawning period was from May to August.The main spawning species were Engraulis japonicus,Nibea albiflora,Saurida elongata,Acanthopagrus schlegelii,Sillago japonica,Pennahia argentata,Callionymus beniteguri,and Cynoglossus joyneri.The dense area of fish eggs was situated in the waters adjacent to the Miaodao Strait,extending from the eastern to southwestern waters of the study area.The main distribution period of fish larvae was from May to July and from November to December.The main larval species were E.japonicus,Hypoatherina valenciennei,Hexagrammos otakii,and Ammodytes personatus.The dense area of fish larvae was situated in the eastern,southwestern,and northwestern waters of the study area.The richness,evenness,and dispersion indices of early life resources community structure and functional diversity of fish were highest during the spring-summer season(May to July).In the
