Diversity of marine organisms from Indonesian shallow waters

在1993财政年度期间，日本研究人员在印度尼西亚Puslitbang海洋学研究所的印度尼西亚研究人员的帮助下，在印度尼西亚东部安汶各地进行了关于鱼类、棘皮动物、软体动物、鱼类寄生虫和甲壳类动物的实地调查和收集。1994年，主要研究地点集中在龙目岛南部面向印度洋的地区，其次是苏拉威西岛北方的万鸦老，以获取比较信息。标本采集于岩礁和珊瑚礁的潮间带，采集方法为海岸采集和皮肤潜水，也可在水深约30 m的浅水区进行水肺潜水。标本也采自桑迪海滩或桑迪泥坪。鱼类标本近2000余件，棘皮动物标本1000余件，其中以海星、脆星鱼为主。日 ...更多信息 安汶的脆星植物已鉴定出9科25种。龙目岛的软体动物标本也被鉴定，有14个多板动物，约170个大型腹足类，约60个双壳类。在这些软体动物中，有12种与琉球群岛的物种非常相同或非常接近，其中有2个新种。头足类标本由研究者自己采集或在鱼市发现，隶属于3科5种。至于十足类甲壳动物，标本数量近1000种，大多数与活珊瑚或平礁共同生活的物种与琉球群岛的物种相同。从系统学、生态学和地理学的观点来看，最有趣的类群是以海参上的小蟹为代表的膜体虫科（Hymenosomatidae）和寄生在活珊瑚上的隐手虫科（Cryptochiridae），它们由约30种寄生虫组成。将扁形动物门的单殖吸虫、双殖吸虫和绦虫，无壳动物门的线虫和棘头虫，以及节肢动物门的桡足类甲壳动物的标本固定和保存，以供科学研究之用。大部分标本也在琉球群岛的鱼类中发现，但在漂流鱼和乌鱼的食道和肠道中发现了一些新的双殖吸虫和线虫。少

During the fiscal year 1993, the field surveys and collections were made at various places of Ambon, eastern Indonesia, on fishes, echinoderms, mollusks, fish parasites and crustaceans by the Japanese research members with help of the Indonesian researchers of the Puslitbang Oceanology, LIPI. Most of the specimens collected were sent to Japan for detailed systematic study in the laboratory.In 1994, the main fields for research were focused on the southern places of Lombok faced to the Indian Ocean, with subsidiary locality, Manado in northern Sulawesi to get the comparative information. The specimens were collected at intertidal zone of the rocky and coral reefs by shore collecting and skin diving, and also at shallow water down to about 30 m depth by SCUBA diving. The specimens were also collected from sandy beach or sandy mud flat. The fish specimens attain almost to 2000, and the echinoderm specimens, most of which are referred to starfishes and brittle-stars, are more than 1000. Th … More e brittle-stars from Ambon were already identified and referred to 25 species of 9 fimilies. The mollusk specimens from Lombok were also identified, with 14 polyplacophorans, about 170 large gastropods, and about 60 bivalves. Of these mollusk species, 12 are quite identical to, or very closely related to the species from the Ryukyu Islands, with 2 new species. The cephalopod specimens were collected by the researchers themselves or found at the fish market, being referred to 5 species of 3 families. As for the decapod crustaceans, numbers of the specimens are almost 1000, and most of the species living with the living corals or flat reef is common with those from the Ryukyu Islands. Most interesting group in the systematical, eclological and also biogeographical viewpoints are the hymenosomatidae which is represented by the small crabs associated with sea-cucumbers, and the Cryptochiridae which are composed of about 30 species parasitic to the living corals.Fish parasites were collected from the gill and intestine of fresh fish caught at fish market. The specimens of monogeneans, digeneans and cestodes of the Platyhelminthes, the nematodes and acanthocephalans of the Aschelminthes, and the copepod crustaceans of the Arthropoda are fixed and preserved for purpose of the scientific study with appropriate technique for each group. Most of the specimens obtained are also found in the fish from the Ryukyu Islands, but some new species of digeneans and nematodes were found from the esophagi and intestines of the driftfish and mullet.
