Data for: High kelp density attracts fishes except for recruiting cryptobenthic species

Adult_and_recruiting_fishes: data describing post-recruit (adult) fish assemblages and the abundance of recruiting cryptobenthic species associated with 28 artificial reefs of different sizes (0.12, 0.24, 0.48, 1.08, 1.92, 4.32, 7.68 m2) and supporting different densities of transplanted kelp (Ecklonia radiata) (0, 4.1, 8.3, 16.6 kelp/m2). Adult assemblages were assessed using diver-based visual surveys conducted at three times (early: spring 2015, middle: autumn: 2016, late: spring 2016). At each time, 2 separate surveys were conducted, and the results were averaged. Recruiting cryptobenthic fishes were assessed using SMURF collectors that were deployed for a six-week period in the centre of each reef on four consecutive occasions (November 2015 to March 2016).

fish_community_structure: data quantifying the density (abundance/reef area) of fish species across artificial reefs of different size (4.32m2, 7.68m2) and supporting different densities of transplanted kelp (Ecklonia radiata) (zero (0 kelp/m2), low (4.1 kelp/m2), medium (8.3 kelp/m2), high (16.6 kelp/m2) )at three times (early (spring 2015), middle (autumn 2016), late (spring 2016)). Assemblages were assessed using diver-based visual surveys conducted at the three times. At each time, 2 separate surveys were conducted, and the results were averaged. The reef code (column headings) conveys the size of the reef (m2), followed by the density of transplanted kelp, followed by the sampling time. For example: 4.32_zero_early indicates that the reef is 4.32m2, supports zero kelp (0 kelp/m2) and the data is based on surveys during the early stage of the experiment (i.e. spring 2015). The different rows are for the different species of fishes that were observed.

Adult_and_recruiting_fishes 数据集：该数据集描述了28个不同尺寸（0.12、0.24、0.48、1.08、1.92、4.32、7.68 m²）的人工鱼礁相关的补充后（成体）鱼类群落组成，以及补充性隐蔽底栖鱼类的丰度；这些人工鱼礁同时搭载了不同密度的移植囊链藻（Ecklonia radiata），密度梯度为0、4.1、8.3、16.6 株/m²。成体鱼类群落采用潜水员目视调查法开展评估，共设置3次采样时段：早期（2015年春季）、中期（2016年秋季）、晚期（2016年春季）。每个时段均开展2次独立调查，最终结果取两次调查的平均值。补充性隐蔽底栖鱼类则采用SMURF采集器进行评估：连续四轮将采集器部署于每个鱼礁中心，每次放置时长为6周，采样时段覆盖2015年11月至2016年3月。

fish_community_structure 数据集：该数据集量化了不同尺寸（4.32 m²、7.68 m²）的人工鱼礁上各鱼类物种的密度（丰度/鱼礁面积）；这些人工鱼礁搭载了不同密度的移植囊链藻（Ecklonia radiata），密度分为零（0 株/m²）、低（4.1 株/m²）、中（8.3 株/m²）、高（16.6 株/m²）四个梯度，采样时段同样为3次：早期（2015年春季）、中期（2016年秋季）、晚期（2016年春季）。鱼类群落组成采用潜水员目视调查法进行评估，共开展3次采样；每个采样时段均完成2次独立调查，结果取平均值。数据集的列标题（礁体编码）包含三项信息：礁体尺寸（单位：m²）、移植海带密度、采样时段。例如：4.32_zero_early 表示该鱼礁尺寸为4.32 m²，搭载的囊链藻密度为0株/m²，数据基于实验早期（即2015年春季）的调查结果。数据集中的不同行对应观测到的不同鱼类物种。
