守护北部湾“海洋活化石”

Core Viewpoint - The article highlights the importance of horseshoe crab conservation, emphasizing ongoing research and monitoring efforts in the Beibu Gulf to protect this ancient marine species, which is crucial for marine biodiversity [4][5]. Group 1: Research and Monitoring Efforts - The Fourth Institute of Oceanography has been conducting surveys of horseshoe crab resources in the Beibu Gulf, providing essential scientific support for the conservation of this valuable species [4]. - A long-term monitoring network has been established in key habitats such as Shatian and Zhulin, allowing researchers to accurately track population dynamics, distribution patterns, and habitat changes [4]. - This year's survey has successfully completed field monitoring of three important horseshoe crab habitats, focusing on both population and environmental quality assessments [4]. Group 2: Data Collection and Analysis - The research team collected sediment and water samples from habitats to analyze environmental factors affecting horseshoe crab survival and reproduction, which will inform habitat protection and restoration efforts [4]. - In the previous year's monitoring, a notable density of horseshoe crabs was recorded in the Shatian area, reaching 46.88 individuals per 100 square meters, indicating a relatively healthy habitat and the potential success of long-term conservation efforts [5]. Group 3: Regional and Global Collaboration - The Fourth Institute of Oceanography joined the Asia-Pacific Horseshoe Crab Observation Network in 2021, promoting standardized monitoring methods and international sharing of conservation experiences and research results [5].
