摘要

本研究以盐渍蒿(Artemia salina nauplii)为食物来源，研究了主要分布在泰国和密克罗尼西亚联邦的两属(Acropora和Pocillopora)三种珊瑚的捕获率和猎物消化情况。此外，研究了珊瑚在白天和夜间的摄食情况。结果表明，在光照和黑暗条件下，千叶鹿角(Acropora millepora)、大鹿角(Acropora nobilis)和达美角鹿角(Pocillopora damicornis)三种珊瑚都能捕获和消耗无水棘藻。3种昆虫的捕获率在0.44 ~ 2.39只/个/12 h之间。结果表明，千叶拟虫和大叶拟虫在2 h内就完全消化了naplplii，而达米角拟虫则需要2.5 h才能完全消化。尽管用青蒿喂养珊瑚并不是一个新发现，因为它被广泛使用，但青蒿对珊瑚的最佳每日摄食频率的研究结果可能适用于人工饲养或水族馆中珊瑚的最佳生长和生存。

Feeding behaviors of three tropical scleractinian corals in captivity

This study examined the capture rates and prey digestion of three corals species in two genera (Acropora and Pocillopora) found dominantly in Thailand and the Federated States of Micronesia using Artemia salina nauplii as a food source. In addition, feeding during day and night times of corals was investigated. Results showed that all three coral species, namely, Acropora millepora, Acropora nobilis, and Pocillopora damicornis captured and consumed A. salina nauplii under both light and dark conditions. The capture rates of the three species ranged between 0.44 and 2.39 individuals/polyp/12 h. The results also showed complete digestions of A. salina nauplii by A. millepora and A. nobilis after 2 h, whereas P. damicornis took 2.5 h to complete the prey digestion. Even though feeding corals with Artemia is not a novel implication since this is widely used, the results of optimum daily feeding frequency of corals by Artemia may be applied for optimum corals growth and survival in captivity or aquarium.

期刊介绍： Tropical Zoology is an international zoological journal publishing original papers in the field of systematics, biogeography, phylogeny, ecology and conservation of all terrestrial and aquatic animal Phyla from tropical and subtropical areas. Only papers with new information, high quality and broad interest are considered. Single species description and checklists are not normally accepted. Review papers are welcome. The journal is owned by the Istituto di Ricerca sugli Ecosistemi Terrestri of the Consiglio Nazionale delle Ricerche, Florence, Italy (CNR-IRET) who performs research into the structure and functioning of aquatic and terrestrial ecosystems, focusing in particular on anthropogenic pressure and global change. The knowledge amassed forms the scientific basis for identifying the most appropriate protective and corrective interventions, and provides support for the bodies entrusted with formulating policies for environmental protection and recovery.
