The preparation of the rice coral Montipora capitata nubbins for application in coral-reef ecotoxicology

Securing adequate and appropriate source material for coral-reef ecotoxicology studies is a significant impediment to conducting various experiments supporting the goal of conserving coral-reef ecosystems. Collecting colonies from wild stocks may be counter to protecting coral reef populations. To address this issue the rice coral Montipora capitata was used to generate sufficient genetically identical nubbins for research purposes. Growth and survival rates of these laboratory-prepared M. capitata nubbins were studied over a period of 90 days. The resulting data support the conclusion that the laboratory-prepared M. capitata nubbins showed successful growth and survival rates and are the best solution to solve the source material issue for lab experimentation. This paper describes the laboratory method used for the preparation and maintenance of these M. capitata nubbins and discusses the benefits and difficulties of using these nubbins in ecotoxicity studies.
