Study on marine biodiversity in the shallow waters of Vietnam

本文于2001 - 2003年对越南浅水区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。采用底拖网、水肺潜水、浮潜、网捕等方法采集标本。主要的研究地点设在越南北部和南部。在越南北部，从海防乘船1小时的卡巴被选为研究对象。在Catba中，我们用底拖网在东京湾约30-40 m的泥泞和沙质海底采集了标本，也用水肺采集了一些无脊椎动物标本。在越南南部，调查是在海岸附近有珊瑚礁的芽庄进行的。在Nba庄，研究小组由海洋研究所提供设备。在收集到的标本中，有许多有趣的物种，包括新种和越南首次记录的物种。收集到的标本分为水螅类、甲壳类、软体动物、鱼寄生虫和鱼类。在藏品中发现的新物种包括一些多placophora和鱼类。本研究收集到的种类最多的是鱼类，共发现71科120属200余种，待进一步研究后可达300余种。收集到的标本包括两类，一类是来自东京湾的底栖物种，另一类是来自芽庄的珊瑚礁动物。越南北部的收集包括一些在温带水域发现的物种，如中国和日本，然而，越南南部的收集主要由主要在珊瑚礁中发现的热带物种组成。虽然在得出越南北部和南部的动物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浅水地区的海洋动物具有很强的生物多样性。这项研究的结果将发表在国家科学博物馆的专著系列中。少

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
