项目摘要

Marine animals inhabiting shallow waters in Vietnam were studied in the periods from 2001 to 2003. Surveys were done under the cooperation of the National Science Museum, Tokyo, and the Research Institute for Marine Fisheries, Haiphong. Specimens were collected by using bottom trawl, SCUBA diving, snorkeling, and nets. Major study sites were stationed in the northern and southern Vietnam. In northern Vietnam, Catba, being 1 hour by boat from Haiphong, was selected for this study. In Catba specimens were collected from muddy and, sandy bottoms in Tonking Bay at depths about 30-40 m by bottom trawl and some invertebrate specimens were also obtained by SCUBA. In southern Vietnam, the survey was made in Nha Trang having coral reefs near shore. In Nba Trang the research team was provided facilities by the Institute of Oceanography.In the collected specimens there are many interesting species including new species and those recorded for the first time from Vietnam. The collected specimens we … More re classified into hydrozoans, crustaceans, mollusks, fish parasites, and fishes. The new species found in the collection include some polyplacophoras and fishes. The greatest number of species collected in this study appears in fishes in which about 200 species belonging to 120 genera of 71 families were found, but the number of fish species may attain to about 300 species when the further study on the collections is made.The collected specimens include two categories, one representing bottom dwelling species from Tonking Bay and the other from coral reef animals from Nha Trang. The northern Vietnam collections include some species found in temperate waters such as China and Japan, however, the southern Vietnam collections are mainly composed of tropical species primarily found in coral reefs. Although it is clear that further studies should be made before we conclude faunal characters of northern and southern Vietnam, the specimens collected by our project show great biodiversity of marine animals found in shallow waters of Vietnam. The results of the study will be published in a series of the National Science Museum Monographs. Less

2001年至2003年期间，对栖息在越南浅水沃茨的海洋动物进行了研究。调查是在东京国立科学博物馆和海防海洋渔业研究所的合作下进行的。采集标本的方法包括底拖网、水肺潜水、浮潜和网具。主要研究中心位于越南北方和南方。在越南北方，Catba，从海防乘船1小时，被选为本研究。在Catba中，利用底拖网在东京湾30-40 m深度的泥质和桑迪底中采集了标本，并利用SCUBA采集了一些无脊椎动物标本。在越南南部，调查是在芽庄进行的，那里靠近海岸有珊瑚礁。在芽庄的研究小组提供的设施由海洋学研究所.在收集的标本有许多有趣的物种，包括新物种和那些记录首次从越南.我们收集的标本 ...更多信息再分为水螅虫、甲壳类动物、软体动物、鱼类寄生虫和鱼类。在收集中发现的新物种包括一些polyplacophoras和鱼类。本研究所采集的鱼类标本数量最多，约有200种，隶属于71科120属，进一步研究后可能达到300种左右。一个代表来自东京湾的海底栖息物种，另一个来自芽庄的珊瑚礁动物。越南北方的采集包括一些在温带沃茨如中国和日本发现的物种，然而，越南南部的采集主要由主要在珊瑚礁中发现的热带物种组成。虽然很明显，在我们得出越南北方和南方的区系特征之前，还需要进一步的研究，但我们项目收集的标本显示，越南沃茨中发现的海洋动物具有很大的生物多样性。研究结果将在国立科学博物馆专著系列中发表。少
