China's marine ecological efforts have led to notable recoveries in the population and habitats of rare marine species, with continued restoration initiatives driving progress nationwide.
Changdao Island, located in east China's Shandong Province, is an important habitat for the spotted seals, a species under first class national protection.
Local authorities have been promoting the establishment of marine nature reserves to provide a favorable ecological environment for these seals.
The area boasts an excellent marine ecological environment with over 600 species of marine life, including fish, shrimp, crabs, and algae, making it an ideal "refueling station" for spotted seals. And this year, more than 50 spotted seals have migrated to Changdao Island.
To further enhance the protection of spotted seals, Changdao has continued to advance marine ecological restoration efforts, constructing four hectares of seaweed beds and seven hectares of seaweed fields, while deploying 35,000 ecological reef structures to improve the seabed environment.
"By protecting the spotted seal, a rare species, we can also safeguard 97 percent of the important rare and endangered marine species in the Yellow and Bohai Seas, along with over 70 percent of the shallow coastal wetlands, which carries even greater significance," said Zhao Zhaohui, research fellow from the First Institute of Oceanography under Ministry of Natural Resources (MNR).
Meanwhile, the Chinese horseshoe crab - the national second-class protected species, is primarily distributed along China's southern coastal areas, with its survival and reproduction heavily influenced by water temperature.
This year, a breeding base in east China's Fujian Province has utilized artificial temperature control technology to induce early spawning, allowing for a longer high-temperature growing period for the larvae.
The base has achieved a new milestone, nurturing over 300,000 horseshoe crab larvae.
"This approach allows for more time in larval development, particularly in July and August when growth rates are relatively fast, which is foundational for large-scale larval cultivation," said Chen Zhi, an expert on freshwater fishery research from Fujian Provincial Bureau of Ocean and Fisheries.
Starting in June, Fujian plans to release 100,000 horseshoe crab larvae in their third to fifth instar stage in batches, with regular monitoring of their growth and assessments of the impact on intertidal ecosystems, aiding in the recovery of the horseshoe crab population and marine ecological protection.
The MNR on Sunday released the 2024 version of monitoring bulletin for marine ecology, indicating that the overall marine ecological status in China remains stable for 2024. Certain local marine areas have shown improvement, with typical ecosystems primarily characterized as good and stable.
