The study of deep-sea fish fauna is hampered by a lack of data due to the difficulty and high cost incurred in its surveys and collections. Taiwan is situated along the edge of the Eurasia fig, at the junction of three Large Marine Ecosystems or Ecoregions of the East China Sea, South China Sea and the Philippines. As nearly two-thirds of its surrounding marine ecosystems are deep-sea environments, Taiwan is expected to hold a rich diversity of deep-sea fish. However, in the past, no research vessels were employed to collect fish data on site. Only specimens, caught by bottom trawl fishing in the waters hundreds of meters deep and missing precise locality information, were collected from Dasi and Donggang fishing harbors. Began in 2001, with the support of National Science Council, research vessels were made available to take on the task of systematically collecting deep-sea fish specimens and occurrence records in the waters surrounding Taiwan. By the end of 2006, a total of 3,653 specimens, belonging to 26 orders, 88 families, 198 genera and 366 species, were collected in addition to data such as sampling site geographical coordinates and water depth, and fish body length and weight. The information, all accessible from the "Database of Taiwan's Deep-Sea Fauna and Its Distribution (http://deepsea.biodiv.tw/)" as part of the "Fish Database of Taiwan," can benefit the study of temporal and spatial changes in distribution and abundance of fish fauna in the context of global deep-sea biodiversity.
由于深海鱼类调查和收集工作难度大、成本高，缺乏相关数据，这阻碍了对深海鱼类区系的研究。台湾位于欧亚板块边缘，处于东海、南海和菲律宾这三个大型海洋生态系统或生态区的交界处。由于其周边近三分之二的海洋生态系统为深海环境，预计台湾拥有丰富多样的深海鱼类。然而，过去没有研究船用于现场收集鱼类数据。仅从大溪和东港渔港收集了一些通过底拖网在数百米深水域捕获的标本，这些标本缺少精确的产地信息。2001年开始，在国科会的支持下，提供了研究船来承担系统收集台湾周边海域深海鱼类标本和出现记录的任务。到2006年底，除了采样地点地理坐标、水深以及鱼体长度和重量等数据外，还共收集了3653个标本，分属26目、88科、198属、366种。这些信息作为“台湾鱼类数据库”的一部分，均可从“台湾深海动物区系及其分布数据库（http://deepsea.biodiv.tw/）”获取，有助于在全球深海生物多样性背景下研究鱼类区系分布和丰度的时空变化。
