Description
Dongsha Atoll, situated in the northern part of the South China Sea, is surrounded by coral reefs and deep-sea habitats. The coastal areas of the atoll, a marine protected area, serve as important nursery habitats for many reef fish species. At the same time, the offshore deep-sea continental slopes are historically important fishing grounds. Although previous inventories primarily focused on coral reef fishes within the atolls listing 340 species in 99 families, comprehensive surveys of fishes from deeper waters have been incomplete. In this study, we aim to update the species composition of fish fauna around Dongsha Island by analyzing large volumes of frozen bycatch from commercial deep-sea trawlers operating in the area for three years and reviewing the existing literature. We updated the new occurrences of 137 species belonging to 90 families, including potentially undescribed species. This dataset will assist further taxonomic works and significantly enhance the understanding of marine biodiversity in the South China Sea.

Méthodes d'échantillonnage
Commercial bottom trawlers operated in the waters off Dongsha Island at depths of around 300 to 600 meters (coordinates 18°49' to 20°45'N and 112°46 to 116°15'E). From February to early July each year from 2021 to 2024, we obtained frozen samples from fishermen at Zhengbin fish port in Keelung, Taiwan. These samples mainly consisted of fishes and other invertebrates and weighed approximately 30 kg each. The total samples (n = 198) we processed collectively weighed over 5,000 kg.
| Etendue de l'étude | Our study used two distinct datasets: occurrence records from the literature on coral and seagrass-associated shallow-water fishes and newly collected occurrence data from deep-water fishes sampled via commercial bottom trawlers. Both datasets represent different ecological settings with distinct sampling techniques. For the former, we reviewed existing literature and validated nomenclatures. |

Description des étapes de la méthode:
- Our samplings were conducted bi-monthly, and selections were made to represent as diverse a range as possible of the catch. These samples were then transferred to our lab and defrosted sequentially. These otoliths were coated with a thin layer of gold using an ion sputter machine (MCM-100P, Sec, South Korea) to enhance the visibility of the sulcus. Additionally, for small-sized otoliths, images were captured using a scanning electron microscope (JSM-7100FLV, Jeol, Japan). Otoliths were archived at the marine paleontology lab, Biodiversity Research Center, Academia Sinica, registered under the code CHLOL.
