Long-term monitoring dataset of fish assemblages in rocky tidepools on the southern coast of Taiwan

Long-term data of fish assemblages collected in the rocky intertidal zone provides a valuable resource for elucidating the temporal variations in species diversity and intertidal ecosystems. We describe a long-term time-series dataset of fish collected by counting the number of anesthetized fish at sampling stations in the rocky tidepools on the southern coast of Taiwan. The species assemblages were monitored seasonally at the two stations for 16 y (2000–2008 and 2012–2018). In total, 86 samples containing 5137 individuals belonging to 82 species were recorded. Our data can be used for elucidating the temporal variations in fish assemblages and intertidal ecosystems and as background information for the resilience of the fish community conservation in coastal areas. The current study presents valuable data for researchers to understand the temporal and spatial variations in species abundance, richness, diversity, and composition in relation to climate change, environmental factors, and human activities.

在岩质潮间带采集的鱼类群落（fish assemblages）长期数据，为解析物种多样性与潮间带生态系统的时间动态变化提供了宝贵研究资源。本数据集记录了台湾南部海岸岩质潮池中，通过计数麻醉鱼类数量所采集的长期时间序列鱼类观测数据。研究团队于两个采样站位按季度对鱼类群落开展监测，监测时长共计16年（2000年至2008年、2012年至2018年）。总计记录有效样本86份，涵盖82个物种共5137尾个体。本数据集可用于解析鱼类群落与潮间带生态系统的时间动态变化，同时可为沿海区域鱼类群落保护的恢复力研究提供背景支撑数据。本研究提供的宝贵数据，可供研究者探究物种丰度、物种丰富度、多样性及群落组成随气候变化、环境因子与人类活动产生的时空动态变化。
