The ecological significance of cleaner fish on coral reefs was investigated. I removed all cleaner fish, Labroides dimidiatus, from eight small reefs, measured the subsequent effect on the abundance and species composition of all reef fish after 3 and 6 months, and compared it with eight control reefs with cleaner fish. The removal of cleaner fish had no detectable effect on the total abundance of fish on reefs and the total number of fish species at both times. Multivariate analysis by non-metric multidimensional scaling and ANOSIM pairwise tests based on 191 fish species revealed no effect of cleaners on the community structure of fish. Similar results were obtained using principal components analysis on subsets of the data using the 33 most common fish species and the 15 most abundant species (≥5 individuals per reef ) with both log10 (x + 1) transformed data and with fish numbers standardized for abundance. This study demonstrates that the removal of cleaner fish for 6 months did not result in fish suffering increased mortality nor in fish leaving reefs to seek cleaning elsewhere.
研究了清洁鱼在珊瑚礁上的生态意义。我从八个小珊瑚礁中移除了所有的清洁鱼——裂唇鱼，测量了3个月和6个月后对所有礁栖鱼类丰度和物种组成的后续影响，并将其与有清洁鱼的八个对照珊瑚礁进行比较。移除清洁鱼对两个时间点的珊瑚礁鱼类总丰度和鱼类物种总数均未产生可检测到的影响。基于191种鱼类的非度量多维标度和ANOSIM成对检验的多变量分析表明，清洁鱼对鱼类群落结构没有影响。使用主成分分析对数据子集进行分析，分别采用33种最常见的鱼类以及15种最丰富的物种（每个珊瑚礁≥5个个体），对数据进行log10（x + 1）变换以及对鱼类数量进行丰度标准化，均得到了类似的结果。这项研究表明，移除清洁鱼6个月并不会导致鱼类死亡率增加，也不会导致鱼类离开珊瑚礁到其他地方寻求清洁服务。
