As a key species in marine ecosystems,horseshoe crabs possess remarkable ecological,medicinal and scientific research value.Limulus reagents extracted from their blood is widely applied in multiple fields.However,due to overfishing,habitat destruction,climate change and other factors,the number of global hor-seshoe crab populations has declined sharply,which seriously threatens the survival of species and the sus-tainable development of related industries.This article aims to systematically review the current progress in the conservation and restoration of horseshoe crab resources,and deeply analyze the key challenges they face,so as to provide scientific references for future conservation actions.This article reviews the global conserva-tion practices and achievements of horseshoe crab resources from three aspects:policies and regulations,sci-entific research,and artificial breeding technology.Analysis reveals that the current conservation of horseshoe crab resources still faces severe challenges.At the ecological level,the continuous degradation of habitats and the aggravation of environmental pollution lead to the decline of wild populations.At the technical level,the immature artificial breeding technology,the lack of long-term tracking and monitoring system,and the lag-ging research and development of horseshoe crab alternative reagent have restricted the effectiveness of con-servation and release programs.At the industrial and social levels,the production of horseshoe crab reagent remains heavily dependent on wild resources.Meanwhile,weak public conservation awareness further aggra-vates the existing conservation dilemma.This article argues that although conservation efforts have been car-ried out in various aspects,they are far from meeting the requirements for the effective restoration of horse-shoe crab resources.In the future,scientific research,policy management,social participation and resource guarantee must be carried out simultaneously to achieve long-term protection and sustainable utilization of horseshoe crab resources.
