On July 10, 2024, in the ecological aquaculture area of the Ailun Bay Marine Ranch in Rongcheng City, Shandong Province, fishermen drove fishing boats and sampans to shuttle between colorful ecological aquaculture floats, carrying out marine operations such as aquaculture management, shellfish seeding, and harvesting of asparagus. Aquaculture float is an important production material for marine aquaculture. Due to its material, traditional plastic floats are prone to damage to the marine ecological environment. In recent years, major marine ranches in Rongcheng City have begun to promote the use of this new type of colored ecological aquaculture float. This float has achieved comprehensive surpassing in physical and environmental performance, not only beautiful and durable, but also does not cause pollution to seawater and the environment, making the aquaculture area achieve the goals of ecology, low-carbon, environmental protection, health, green, and efficiency enhancement.
