Abstract

The aim of this study was to know the nematocysts composition of Montipora undata (Scleractinia) which was collected in the Malalayang coastal coral reef, Manado Bay. This research was conducted for three months, from October to December 2020. Observation of nematocysts was done under an Olympus CX41 microscope with a magnification of x100 objective lens connected to a computer equipped with the application of Optica view 7 at the Laboratory of Fish Health, Environment and Toxicology, Faculty of Fisheries and Marine Sciences, UNSRAT. The results showed that M. undata had the main nematocyst composition, namely microbasic b-mastigophore (MbM) of 60.0 %, small microbasic p-mastigophore type II (sMpM-II) 26.67 %, small holotrichous isorhiza (sHI) 6 ,67 %, large holotrichous isorhiza (lHI) 4.44 %, and large microbasic p-mastigophore type II (lMpM-II) 2.22 %. MbM is the dominant type of nematocyst for this coral species. Further studies are suggested to investigate the function of MbM and morphology of nematocysts of various types of corals in the genus Montipora.Keywords: Composition, Manado Bay, Montipora undata, nematocyst, Scleractinia

本研究的目的是了解在万鸦老湾马拉拉扬沿海珊瑚礁中采集到的黑线藻(Montipora undata)的线虫囊组成。这项研究从2020年10月到12月进行了三个月。在UNSRAT渔业和海洋科学学院鱼类健康、环境和毒理学实验室，在放大率为x100的奥林巴斯CX41显微镜下观察刺丝囊，该显微镜与配备Optica view 7应用程序的计算机相连。结果表明，密缕草的主要刺丝囊组成为微碱性b型刺丝团(MbM)占60.0%，小微碱性p型刺丝团II型(sMpM-II)占26.67%，小全毛刺丝团(sHI)占6.67%，大全毛刺丝团(lHI)占4.44%，大微碱性p型刺丝团II型(lMpM-II)占2.22%。MbM是这种珊瑚的主要刺丝囊类型。建议进一步研究不同种类蒙提波拉属珊瑚中丝囊的形态和MbM的功能。关键词:成分，万鸦鸦湾，太子参，线虫囊，菌核菌
