- Abstract
This study examined the capture rates and prey digestion of three corals species in two genera (AcroporaandPocillopora) found dominantly in Thailand and the Federated States of Micronesia usingArtemia salinanauplii 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, andPocillopora damicorniscaptured and consumedA. salinanauplii 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 ofA. salinanauplii byA. milleporaandA. nobilisafter 2 h, whereasP. damicornistook 2.5 h to complete the prey digestion. Even though feeding corals withArtemiais not a novel implication since this is widely used, the results of optimum daily feeding frequency of corals byArtemiamay be applied for optimum corals growth and survival in captivity or aquarium.
