项目摘要

In 1993 preliminary surveys were carried out at here toxic plankton or intoxicated shellfish was reported in the Philippines and Indonesia. As extensive toxic red tides had occurred with many victims, intensive research were made at 10 areas of the Philippines. No toxic dinoflagellate was found in plankton samples , however, many cysts were in sediment in some of the areas. Paralytic and diarrhetic toxins were detected in shellfish specimens collected at Camiguin Island of Mindanao Island. This is the first finding of the diarrhetic toxins in tropical area. Causative organisms were confirmed as Dinophysis caudata and D. miles by following researches conducted at Sapian Bay, Panay Island.In 1994 the main survey was conducted in Manila Bay. Water quality was highly eutrophic. Total nitrogen was 87 muM at maximum (average 29.4 muM) and total phosphorus 10.3 muM (average 4.15 muM). As water contained more particulate matters than soluble nitrogen and phosphorus, up-take rate into phytoplankton and turn over rates of the elements were presumed to be high. Sedimentation rate was 0.91 cm/yr. at the central area and 1.5 cm/yr. at the east coast. The toxic dinoflagellate, Pyrodinium bahamense, was distributed in shallower waters than 6 m of innermost and Bataan coast areas. The resting cyst of the species was widely found in surface and deeper sediments accumulated several decades ago. Therefore the species was presumed to have been recurring in the area several times in the decades, but recently recognized after incidents of red tide and intoxication of shellfish.In Indonesia intensive surveys were conducted at Jakarta Bay and Flores Islands, but no paralytic toxin producer could be found. Benthic toxic species, Prorocentrum lima was found in Flores islands. In Malaysia Pyrodinium bahamense was found. In China Alexandrium spp. were confirmed as toxic species in southern coastal waters.

1993年，在菲律宾和印度尼西亚进行了初步调查，报告了有毒浮游生物或中毒贝类。由于有毒红潮在菲律宾广泛出现，受害者众多，因此，专家组在菲律宾10个地区进行了深入研究。在浮游生物样品中没有发现有毒甲藻，但在一些地区的沉积物中发现了许多孢囊。在棉兰老岛的卡米金岛采集的贝类样品中检测到麻痹性和类毒素。这是首次在热带地区发现的寄生虫毒素。经鉴定，病原菌为尾甲藻（Dinophysis caudata）和D. 1994年在马尼拉湾进行了主要调查。水质高度富营养化。总氮最高为87 μ M（平均29.4 μ M），总磷为10.3 μ M（平均4.15 μ M）。由于水体中颗粒物的含量高于可溶性氮和磷，浮游植物对这些元素的吸收率和转化率被认为很高。沉积速率为0.91厘米/年。中心区为1.5cm/年。在东海岸。有毒甲藻，Pyrodinium bahamense，分布在最里面和巴丹海岸地区的浅沃茨6米。该物种的休眠孢囊广泛存在于几十年前积累的表层和深层沉积物中。在印度尼西亚的雅加达湾和弗洛雷斯群岛进行了密集的调查，但没有发现麻痹性毒素产生者。在弗洛雷斯群岛发现了底栖有毒物种，Prorocentrum lima。在马来西亚发现了巴哈马甲藻（Pyrodinium bahamense），在中国发现了亚历山大藻（Alexandrum spp.）在南部沿海沃茨被证实为有毒物种。
