珊瑚礁鱼类群落通常包括数百种同域物种，这些物种对珊瑚礁保护和渔业管理人员非常感兴趣。对鱼类声音的长期声学监测可用于推断周期性生殖活动和种群丰度的变化。然而，有限的记录的声音生产的珊瑚礁物种排除了应用程序的声音监测在人口或社区水平。我们使用呼吸器和数字声/视频技术，以产生一个声音库的鱼类在珊瑚礁的西夏威夷岛，HI，美国。我们记录了85个声音产生的45（47%）的96个居民物种，与竞争的相互作用和资源防御，繁殖，巢防御，喂养和警惕行为。大多数非进食声音由单个或一连串<100 ms长的脉冲事件组成，这些脉冲事件分布在<100至1000 Hz的频谱上，其中大部分峰值频率在100和300 Hz之间。在食物，空间或巢育雏资源的竞争性相互作用过程中产生的激动性声音被确定为大坝selfishes，外科鱼类，蝴蝶鱼，和触发鱼，等等。与求偶、产卵或巢穴防御有关的生殖声音是由豆娘鱼、山羊鱼、蝴蝶鱼、刺尾鱼和外科鱼以及濑鱼和摩尔神像产生的。某些鹦嘴鱼和叉尾鱼在较高频段（2 ~ 6 kHz）记录到的明显的外来摄食声可能是摄食活动和礁生物侵蚀速率的有用指标。这是第一项研究，以描述特定的行为声景，可应用于声学监测的珊瑚礁鱼类群落。
Coral reef fish communities often include hundreds of sympatric species which are of great inter- est to reef conservation and fisheries managers. Long- term acoustic monitoring of fish sounds can be used to infer periodic reproductive activity and changes in pop- ulation abundance. However, limited records of sound production by coral reef species have precluded the ap- plication of acoustic monitoring at the population or community levels. We used rebreather and digital acoustic/ video techniques to produce a sound library for fishes on coral reefs of west Hawai'i Island, HI, USA. We documented 85 sounds produced by 45 (47%) of the 96 resident species that were associated with agonistic interactions and resource defense, reproduction, nest defense, feeding, and vigilance behaviors. Most non- feeding sounds consisted of single or trains of pulse events <100 ms long that were distributed across a spectrum of <100 to 1000 Hz with the majority of peak frequencies between 100 and 300 Hz. Agonistic sounds created during competitive interactions over food, space, or nest brood resources were identified for dam- selfishes, surgeonfishes, butterflyfishes, and trigger- fishes, among others. Reproductive sounds associated with courtship, spawning, or nest defense were pro- duced by damselfishes, goatfishes, butterflyfishes, par- rotfishes, and surgeonfishes, as well as wrasses and Moorish idols. The distinct adventitious feeding sounds recorded for some parrotfishes and triggerfishes oc- curred in a higher frequency band (2�6 kHz) and may be useful indicators of feeding activity and rates of reef bioerosion. This is the first study to characterize the spe- cies-specific behavior soundscape that can be applied to acoustic monitoring of a coral reef fish community.
