摘要

2005 年 10 月，通过水下目测普查，研究了自 20 世纪 70 年代以来日本南部库奇拉布岛潮下暗礁鱼群的变化。将此次调查与 1972 年的数据进行比较后发现，物种数量增加、保持稳定或减少的频率取决于地理范围类别和主要觅食种类。温带草食性鱼类的丰度明显下降，而亚热带肉食性鱼类则有所增加。我们从水温、大型藻床的消失和人类活动的影响等方面讨论了珊瑚礁鱼群变化的原因。

Change in the subtidal reef fish assemblage at Kuchierabu-jima Island, southern Japan, between 1972 and 2005

Change in the subtidal reef fish assemblage at Kuchierabu-jima Island, southern Japan, since the 1970s was investigated using an underwater visual census in October 2005. A comparison of this survey with data from 1972 revealed that the frequencies of species that had either increased, remained stable, or declined in abundance were dependent on the geographic range category and the major feeding guild. Temperate herbivorous fishes had noticeably declined in abundance, while subtropical carnivorous species had increased. We discuss causes of the change in the reef fish assemblage from the aspect of water temperature, loss of macroalgal beds, and anthropogenic impacts.

期刊介绍： Ichthyological Research is an official journal of the Ichthyological Society of Japan and is published quarterly in January, April, July, and November. Ichthyological Research primarily publishes research papers on original work, either descriptive or experimental, that advances the understanding of the diversity of fishes. Ichthyological Research strives to cover all aspects of fish biology, including taxonomy, systematics, evolution, biogeography, ecology, ethology, genetics, morphology, and physiology.
