摘要: 以舟山群岛枸杞岛贻贝筏式养殖区为研究区域,于2022年8月(夏季)、10月(秋季)和2023年2月(冬季)、5月(春季)进行样品采集,分析舟山群岛枸杞岛浮筏海藻群落结构及其对藻栖端足目生物(钩虾和麦秆虫)附生偏好的影响。结果表明: 1)养殖区近岸侧浮筏海藻物种数及生物量均高于离岸侧,且存在一定的季节性波动,其中,夏季海藻物种数最多(19种),冬季最少(15种);物种丰富度指数亦表现为夏季高(2.65)、冬季低(2.38)。2)钩虾和麦秆虫附生密度在各季节间存在极显著差异,且均呈现夏高冬低的季节变化。钩虾多分布于养殖区近岸侧,麦秆虫多分布于离岸侧。3)钩虾和麦秆虫均偏好枝状和叶状海藻,附生密度最大的叶状海藻均为角叉菜;枝状海藻中,钩虾倾向附生于结构复杂、颜色相近的岗村蜈蚣藻上,麦秆虫则倾向附生于表面粗糙、质地坚硬、结构稳定的珊瑚藻。除季节外,分枝数量、表面粗糙度、结构复杂性等形态特征也是影响钩虾和麦秆虫附生偏好的主要因素。研究结果有助于理解端足目生物的生态适应策略,可为筏式养殖区的生态管理和海藻多样性保护提供理论基础和数据支持。

Abstract: We collected samples in the August (summer) and October (autumn) of 2022, as well as in the February (winter) and May (spring) of 2023 in the raft-style mussel aquaculture area on Gouqi Island in the Zhoushan Archipelago, aiming to analyze the structure of the raft-style algal community on Gouqi Island and its impact on the epibenthic preference of algae-dwelling amphipods (Gammaridea and Caprellidae). The results showed that: 1) The number of algal species and biomass on the nearshore side of the aquaculture area were higher than those on the offshore side, with seasonal fluctuations. The number of algal species was highest in summer (19 species) and lowest in winter (15 species). The species richness index was higher in summer (2.65) and lower in winter (2.38). 2) There were significant differences in the epibenthic density of Gammaridea and Caprellidae across seasons, with higher densities in summer and lower densities in winter. Gammaridea was predominantly distributed on the nearshore side of the aquaculture area, while Caprellidae was more abundant on the offshore side. 3) Both Gammaridea and Caprellidae preferred branching and foliar algae, with the foliar algae Chondrus ocellatus exhibiting the highest epibenthic density. Among the branching algae, Gammaridea tended to attach to the structurally complex and color-similar Grateloupia okamura, while Caprellidae preferred to attach to the rough-surfaced, hard-textured, and structurally stable Corallina officinalis. In addition to season, morphological characteristics such as branching number, surface roughness, and structural complexity were also major factors affecting the epibenthic preference of Gammaridea and Caprellidae. The study could contribute to understanding the ecological adaptation strategies of amphipods and provide theoretical basis and data support for ecological management and algal diversity conservation in raft-style aquaculture areas.
