Tachypleus tridentatus is an ancient marine arthropod. Currently, the population of Tachypleus tridentatus has decreased rapidly, in 2019, the IUCN Red List officially updated the endangered status of Tachypleus tridentatus to Endangered (EN), indicating a global decline in the resources of this species. However, the lack of data, such as population baseline data, acts as a barrier for this nearshore habitat and medically important species. The results of this paper suggest that the main causes of the decline in the population of the Tachypleus tridentatus darter are overfishing and habitat destruction. In addition, the discussion focuses on three techniques presently employed in China to revive the population of Tachypleus tridentatus, including fisheries enhancement, habitat designation for conservation, and educational programs. The study also examines the advantages and disadvantages of conservation methods implemented in China, and while certain methods, such as moratoriums on aquaculture, show significant advantages, others, such as the establishment of protected habitats, have limitations due to incomplete findings. These methods provide a solid foundation for the conservation of the Tachypleus tridentatus, and also point to possible future directions, such as the implementation of polyculture. However, there is a need to improve the efficiency of existing methods through further development and additional data collection studies. To address the acknowledged limitations and gaps in this study, additional exploration and discourse are imperative to advance the preservation of Tachypleus tridentatus.
