Mangroves can be found growalong the coast and influenced by tides. This research conducted in Gamlamo Village, Jailolo Sub-district, West Halmahera Regency, North Maluku Province. The purposes of this study were to determine the mangrove community structure and identify mangroves species in Gamlamo Village. The method used in this research was line transect method. There are 3 stations established onthis research area and each station has two line transects, so the total line transect are six. Moreover, within each line transect five quadrants (10 x 10 cm2) were laid. This study found that at three stations in the research area, there were three mangrove species Rhizophora mucronata, Sonneratia alba and Bruguiera gymnorrhiza. The highest density value was found at station 2 of R. mucronata 0,36 ind/m2 and the relative density value was 60%. The highest frequency was found at station 2, belong to R. mucronata 1 ind/m2 and the relative value was 41,67%. The highest dominance wasfound at station 1 of S. alba 52,89 m2 and dominance relative 53,31%. For the highest important value index was at station 2, of R. mucronata with a value of 136,57% and the found at station 3 B. gymnnorrhiza. The highest diversity index (H’) 1,03 was found at station 1 while the lowest 0,95 was at station 2.Keywords: Gamlamo Village, Mangrove, Community Structure","PeriodicalId":17792,"journal":{"name":"JURNAL PESISIR DAN LAUT TROPIS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91497039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The location for the collection of C. vaugani colonies was on the coral reefs of the Malalayang coastal area, Manado. This research was carried out in September - December 2020. The observation of nematocysts of C. vaugani was carried out using an Olympus CX41 microscope with a magnification of x100 objective lens which connected to a computer monitor equipped with an optical view 7 application at the Fish Health Environment and Toxicology Laboratory, Faculty of Fisheries and Marine Science, UNSRAT. The present results showed that C. vaugani had a composition of nematocysts, namely type I microbasic p-mastigophore (MpM-I) of 40.00%, small type II microbasic p-mastigophore (sMpM-II) of 31.11%, small holotrichous isorhizas (sHI) of 24.44 %, large type II microbasic p-mastigophore (lMpM-II) of 2.22%, and large holotrichous isorhizas (IHI) of 2.22%. sMpM-II is the most dominant nematocyst type of C. vaugani and this type of nematocyst is thought to be used by coral for aggression and killing prey or predator if there is disturbance from the surrounding aquatic environment where the coral lives. Further research is recommended to study the types and morphology of nematocyst from various species of coral fungia, including C. vaugani to understand the differences in their types and dimension of the nematocyst.
