1、 Project Background
The Chinese sturgeon is a first-class protected animal in China, known as the "giant panda in water". In April 2025, Hubei Jinlong New Materials Co., Ltd. customized a "slide" - a flexible ecological release slide - for 30000 Chinese sturgeons at the release point of Yichang Yanzhi Garden, helping them safely return to the Yangtze River.
2、 Product Structure
1. Main material: Food grade PVC corner mesh fabric, tear resistant, low temperature resistant, can directly contact water and fish bodies.
2. Buffer layer: A double-layer airbag structure that can absorb over 90% of the impact force, ensuring that fish scales and internal organs are not mechanically damaged.
3. Diversion groove: embedded with a 5 ° inclined spiral pattern, forming a slow flowing "water film" to reduce the sliding friction of sturgeon.
4. Quick retraction: The overall weight of the slide is less than 60 kg, and it can be laid and recycled in 10 minutes by 3 people. It can be folded and stored in a 1 m ³ storage bag, making it convenient for multi-point outdoor release.
3、 Technical highlights
1. Survival rate improvement: Field tests have shown that the instantaneous mortality rate of Chinese sturgeons decreased from 0.5% to 0.2% after using the slide, and the overall survival rate can reach 99.8%.
2. Eco friendly: The material has passed dual environmental certifications of RoHS and REACH, with no plasticizer precipitation, and can be 100% recycled and reused in natural water bodies.
3. Environmental adaptation: The working temperature range is -20 ℃ to 50 ℃, and it can operate normally in rainy and snowy weather.
4、 Application scenarios
1. Rare fish species proliferation and release: Chinese sturgeon, Chinese sturgeon, and cochineal fish.
2. Large scale water conservancy engineering fish crossing dam assistance: with the help of fish lifting machines and fish collection systems, reduce transportation damage.
3. Aquaculture research and teaching: universities and research institutes carry out labeled release and behavior tracking experiments.
5、 Social benefits
Assisted in the "ten-year fishing ban" and ecological restoration of the Yangtze River, and received recognition from the Fisheries and Fishery Administration of the Ministry of Agriculture and Rural Affairs.
Form a tripartite cooperation model of "enterprise+scientific research+protected area", which can be copied to the Pearl River, Lancang River and other basins.
one-sentence summary
Hubei Jinlong used a "soft slide" to allow Chinese sturgeons to "slide" back to their mother river, and also "slide" out a new paradigm of harmonious coexistence between humans and nature.
