摘要:

为恢复濒危物种中国鲎(Tachypleus tridentatus)种群数量，2021—2022年在福建省罗源县开展中国鲎人工驯养繁殖技术研究。基于野外自然产卵场及幼体生境观测结果，构建人工模拟产卵环境，诱导野生亲本在仿生态环境中自然受精、产卵繁殖，并开展了人工孵化和苗种培育研究。研究组初步掌握了中国鲎成体对底质的栖息及繁殖偏好习性和生态需求，形成了适宜福建沿海中国鲎的人工驯养繁殖技术，对中国鲎人工驯养和自然繁殖有重要意义，可为福建沿海中国鲎人工育苗及野外种群资源恢复提供理论基础资料。

Abstract:

To restore the population of the endangered species Tachypleus tridentatus,artificial domestication and breeding research of T.tridentatus was carried out in Luoyuan County,Fujian Province in 2021—2022.Following the observation results of their natural spawning and nursery grounds,the simulated spawning environment was constructed,and the mating pairs were induced to spawn naturally in the artificial environment.The spawning habitat preferences and ecological requirements for T.tridentatus were determined through artificial incubation and seedling cultivation.This paper summarized the artificial domestication and propagation technology of horseshoe crab,and analyzed the significance of artificial domestication and natural propagation of T.tridentatus,providing theoretical basis for species conservation by the protection and restoration of T.tridentatus populations and artificial incubation in Fujian coastal area.
