摘  要：
本研究于枸杞岛西北部贻贝筏式养殖区海藻生长繁盛时期采集11种大型海藻,并对每种海藻及其藻栖钩虾、麦秆虫生物学参数进行测量分析。结果显示,不同海藻上钩虾种群特征存在显著差异,且不同海藻上麦秆虫种群特征也存在显著差异。其中,钩虾最高种群密度和最大个体均出现在厚网藻上;麦秆虫最高种群密度出现在殖丝藻上,最大个体则出现在缢基蜈蚣藻上。同时,对于生物量较小的海藻,其藻栖钩虾、麦秆虫种群密度均更高,钩虾体型无显著变化,但麦秆虫体型更小;另外,比表面积值更高的海藻,其钩虾种群密度更高,个体也更大,但麦秆虫种群密度和个体均无显著变化。研究表明,贻贝筏式养殖生境中不同种类的海藻在藻栖端足目种群特征形成的过程中扮演的功能角色存在一定差异,而海藻自身多样化的生物特征则可能是该差异形成的内在影响因素。

摘  要：
In this study, eleven representative seaweeds were sampled in raft-mussel-culture area, Gouqi Island during the flourishing period of seaweeds. And biological parameters of seaweeds and amphipods associated with each seaweed species were measured. Results showed that the population characteristics of Gammaridea and Caprellidae attached on different seaweed species were significantly different. Both of the highest population density and the largest body size of Gammaridea appeared on Pachydictyon coriaceum. And the highest population density and the largest body size of Caprellidae appeared on Ganonema farinosum and Grateloupia constricata,respectively. Moreover, seaweed species with relatively lower biomass tended to support higher population density of Gammaridea and Caprellidae and smaller size of Caprellidae, but had no significant effect on size of Gammaridea. Furthermore, seaweed with higher surface area to biomass ratio tended to support higher density and larger body size of Gammaridea, but had no significant effect on density or body size of Caprellidae. In a word,our investigation indicated that seaweeds community paly different functional roles in structuring seaweedassociated amphipods population characteristics in mussel raft culture area, which were determined by the diverse seaweed biological traits.
