对出现在热带地区红树林河口的浮游物种的了解仍然很少。我们认为，有关物种出现情况的病例报告数据对于澄清红树林河口的生态系统非常重要。本文根据2012年12月在泰国Samut Songkhram红树林河口观测到的由两种甲藻组成的水华，报告了水华的发生并讨论了影响水华的因素。从荧光显微镜下观察钙荧光白色染色后的甲壳，我们将这些甲藻鉴定为Ceratium Furcaa和Diplopsalis lentula。此外，从当年气温和降水的年度资料中发现，水华出现在旱季早期。此外，在低密度下观察到了抑制甲藻生长的硅藻。这些结果表明，两种甲藻C.Furca.和D.豆状幼体，在硅藻消失期间生长。
Knowledge of the planktonic species that appear in mangrove estuaries in tropical areas is still poor. We believe that case report data on the appearance of species is important for clarifying the ecosystem of the mangrove estuary. We report in this paper on the occurrence of blooms and discuss the factors that influence blooming, based on an observed bloom consisting of two dinoflagellates in the mangrove estuary of Samut Songkhram, Thailand, in December 2012. From fluorescence microscopic observation of the armors of the dinoflagellates after calcofluor white staining, we identified these dinoflagellates asCeratium furcaandDiplopsalis lenticula. In addition, from the annual data on air temperature and precipitation for that year, it was found that the bloom occurred in early dry season. Additionally, diatoms that inhibit the growth of dinoflagellates were observed at low densities. These results suggested that the two dinoflagellates,C. furcaandD. lenticula, grew during disappearance of diatoms.
