Descrição
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 plate, 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.

| Título | Survey of Deep-Sea Fish Diversity by Research Vessels in Taiwan Waters |
|---|---|
| Financiamento | Ministry of Science and Technology, Executive Yuan, R.O.C. (Taiwan) |
| Descrição da Área de Estudo | Taiwan is located on the eastern edge of Asian continental shelf. To the west of Taiwan is the shallow Taiwan Strait, to the northeast is the Okinawa Trough (maximum depth 2,716 m), to the east the complex and diverse Philippine Sea (with deep oceanic trenches), and to the south the South China Sea (maximum depth 5,016 m). These deep-water environments were where the surveys were carried out. |
| Descrição do Design | This study focused on Taiwan’s deep-sea fish fauna which so far hasn’t been investigated much, and hoped to learn if the fauna varies depending on sea area, current and water depth. The specimens caught all went through taxonomic identification and had their collection time, water depth and coordinates recorded. A geographic information system (GIS) on their distributions was established in order to provide references for future academic researches as well as for resource development, management and assessment. One or several specimens per fish species were selected to have their photos taken in color. Keeping to the Barcode of Life tissue preservation techniques, a small piece of tissue was then excised, preserved in 90-95% alcohol and stored at BRCAS in liquid nitrogen canisters. Backup tissue samples were also stored at Livestock Research Institute, COA so that in the future they can be used in the study of molecular biology and genetics. The voucher specimens and whole fish specimens were stored at BRCAS too. All the specimen information was entered into Taiwan Fish Database and is freely accessible to all. |

Métodos de Amostragem
The research vessels used were “R/V Fishery Researcher I,” “R/V Ocean Researcher I” and “R/V Ocean researcher III.” Constrained by limited cable length, the maximum depth sampled was 4,460 meters. Major equipment used were otter trawl, French type beam trawl of 4 m span, ORE type beam trawl of 3 m span and Isaacs-Kidd midwater trawl (IKMT). Once the nets reached the sea bottom, they were towed for one hour at a ground speed of 1.5-2.5 knot for otter trawls and 1.0-1.5 knot for others.
| Área de Estudo | The surveys were carried out from 2001 to 2006 in waters off northeastern Taiwan (Okinawa Trough), eastern Taiwan, southeastern Taiwan (Western Pacific) and southwestern Taiwan (South China Sea). |
|---|---|
| Controle de Qualidade | All the scientific names of fish samples were validated by the updated fish checklist in the “Fish Database of Taiwan” or TaiCOL (http://col.taibif.tw; formerly TaiBNET, http://taibnet.sinica.edu.tw) before they were entered into database. Afterward, they were validated again by matching against FishBase and Catalog of Fishes, California Academy of Sciences for further correction. If a specimen was rare or it might belong to an undescribed or new species, it was photographed in fresh and then both the specimen and its tissue sample were catalogued and deposited at the Biodiversity Research Museum of Biodiversity Research Center, Academia Sinica (ASIZP of BRCAS). The latitude and longitude of trawling routes were plotted on Google Maps and outlier detection was conducted. |
Descrição dos passos do método:
- Step1: Sampling locality and water depth were recorded. Step2: Specimens were roughly classified and counted either right on board or when they reached the shore. Step3: Specimens were shipped back to the lab for species identification, body length and weight measurement, and picture taking. Step4: Specimens were fixed in 10% Neutral Buffered Formalin for one month. Next, they were cleaned with water and preserved in 70% alcohol.
