Horseshoe crabs (Tachypleus tridentatus) was widely spread over the costal area of Taiwan Main Island, Penghu and Kinmen. The appearance of T. tridentatus on the tidal flat could be an indicator of its integrity. According to this study, T. tridentatus populations were mostly spotted around the Penghu and Kinmen sea areas. Only very small amount of T. tridentatus were captured by fishermen around Taiwan Main Island sea area. The population of T. tridentatus in Kinmen has decreased over the past few years and the habitat of the juvenile horseshoe crabs were severely damaged by humans. Therefore conservation act on this species is very crucial.
The conservation and management of T. tridentatus should focus on: (1) classify T. tridentatus as an endangered wild species; (2) set up T. tridentatus protected area; (3) work with the local government/non governmental organizations on conservation of T. tridentatus; (4) conduct artificial horseshoe crabs spawning induction and juvenile horseshoe crab rearing in order to improve the total number of the wild population therefore maximize the conservation effect. |
