A long-term monitoring dataset of fish assemblages in rocky tidepools on the northern coast of Taiwan

The assemblage of fish species in the rocky intertidal zone is highly affected by the destructive impact of human activities and has an extended impact on land-sea interactions. There are a few long-term research projects that have focused on rocky intertidal ecosystems, especially on the resident fish community. Here, we describe a long-term time series dataset of fish collected by counting the number of anesthetized fishes at sampling stations in rocky tidepools in the intertidal zones on the northern coast of Taiwan. The species assemblages were monitored seasonally at three stations from 1999 to 2018. In total, 144 samples containing 1,577 individuals belonging to 106 species were recorded in the surveys. The resulting data can be used as background information for conservation and resilience studies of the fish community in coastal areas and to establish reasonable conservation strategies. This study presents valuable data to ecologists and fisheries biologists interested in understanding the temporal patterns of species abundance, richness, and composition in relation to environmental factors, climate change, and anthropogenic pressures.

岩相潮间带的鱼类物种群落极易受到人类活动的破坏性影响，且其动态变化亦会对陆海相互作用产生深远影响。目前针对岩相潮间带生态系统的长期研究项目较为有限，且多聚焦于其中的定居性鱼类群落。
本研究整理了一套长期鱼类时间序列数据集，数据采自中国台湾北部海岸潮间带的岩相潮池采样站位，通过统计各站位内经麻醉处理的鱼类个体数量完成采集。1999年至2018年间，研究人员于3个采样站位按季节对鱼类物种群落开展监测。本次调查累计记录有效样本144份，涉及106个物种、共计1577尾鱼类个体。
本数据集可作为沿海地区鱼类群落保护与恢复力研究的基础背景资料，亦可用于制定合理的沿岸鱼类保护策略。
本数据集可为致力于探究物种丰度、物种丰富度及物种组成随环境因子、气候变化与人为压力变化的时间动态模式的生态学家与渔业生物学家提供极具价值的研究数据。
