盘锦投放千万尾沙蚕改善生态

Core Viewpoint - The release of 10 million sandworm larvae in the wetlands of Panjin City aims to improve the local ecosystem and provide food for migratory birds, particularly the black-headed gulls during their breeding season [4][5]. Group 1: Ecological Impact - The 10 million sandworm larvae were artificially bred and released after approximately 100 days of cultivation, measuring between 0.8 cm and 1.2 cm [4]. - Sandworms will feed on organic debris, leftover bait, and algae, acting as natural cleaners to reduce water pollution and enhance the organic matter cycle in the wetland [4]. - The introduction of sandworms is expected to improve the habitat for other benthic organisms and enhance the growth of local vegetation, such as the alkali grass [4]. Group 2: Benefits to Black-headed Gulls - Sandworms serve as a high-protein and high-fat food source for black-headed gulls, especially critical during the breeding season when food demand is high [5]. - The release site was strategically chosen to be within 5 to 6 meters of the gulls' breeding area, effectively creating a "dining hall" for the birds [5]. - The initiative is part of a broader wetland protection effort, which has already seen the population of black-headed gulls exceed 10,000 this year [5]. Group 3: Ongoing Research and Monitoring - Panjin City plans to collaborate with Shenyang Agricultural University and other research entities to conduct in-depth studies on wetland restoration, black-headed gull protection, and biodiversity maintenance [5]. - Long-term monitoring will provide technical support for the sustainable release of benthic organisms and ensure the health of the ecosystem [5].
