项目摘要

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.

在1993财政年度期间，日本研究人员在印度尼西亚普斯利邦海洋研究所印度尼西亚研究人员的帮助下，对印度尼西亚东部安邦各地的鱼类、棘皮、软体动物、鱼类寄生虫和甲壳类动物进行了实地调查和收集。采集的标本大部分被送往日本进行详细的实验室系统研究。1994年，主要研究领域集中在面向印度洋的龙目岛南部地区，辅之以苏拉威西岛北部的万寿岛，以获得比较信息。这些标本是通过岸上采集和皮肤潜水在岩礁和珊瑚礁的潮间带采集的，也是通过潜水在浅水至约30m深的水域采集的。标本也采自沙质海滩或沙质泥滩。鱼类标本近2000个，棘皮动物标本1000多个，其中大部分是指海星和脆星。TH…在安邦还发现了更多的e脆星，涉及9门25种。龙目岛的软体动物标本也被鉴定出来，其中有14只多足类，约170只大型腹足动物，约60只双壳类。在这些软体动物中，有12种与琉球群岛的物种非常相似或非常接近，还有2个新种。头足类标本由研究人员自行采集或在鱼市上发现，隶属于3科5种。至于十足类甲壳类，标本数量接近1000个，与活珊瑚或平礁生活的物种大多与琉球群岛的物种相同。在系统、生态和生物地理学观点中，最有趣的一类是膜体科和隐甲科，前者以与海参相关的小螃蟹为代表，后者由大约30种寄生于活珊瑚的物种组成。鱼类寄生虫是从鱼市捕获的鲜鱼的鳃和肠道中采集的。为便于科学研究，对扁形线虫、扁形线虫、棘头虫和尺足类甲壳动物标本进行了固定和保存，并对每组标本进行了适当的技术处理。所获得的大多数标本也在琉球群岛的鱼中发现，但在漂流鱼和乌鱼的食道和肠道中发现了一些新的双生线虫和线虫。较少
