The ecological scheduling test is successfully completed!"Four Fish Fish" under the Three Gorges Dam innovative egg production is innovative

On June 29th, the Water Conservancy Military Conservancy Commission and the Agricultural Rural River Basin Fisheries Administration Supervision and Management Office, China Yangtze River Three Gorges Group Co., Ltd., State Grid Co., Ltd. and other departments and units carried out the Second Three Gorges Reservoir to promote drift. The ecological scheduling test of the ovascular reproduction was successfully completed. After preliminary monitoring and analysis, during this ecological scheduling period, the total egg production volume of the two river sections of Yidu and Shashi reached 15.3 billion capsules and 38.8 billion capsules, of which the "four people fish" of the Yidujiang section reached the output of the ovulation output of the "four people". 8.8 billion capsules, monitoring the total egg yield and the "four people fish" egg yield reached a record high, and the effect of ecological scheduling test was significant.

Following the launch of the first ecological scheduling test in early June, the Yangtze River Commission combined with the test -related monitoring and the water forecast and dispatch of the Three Gorges Reservoir, and organized relevant units to analyze the test effects in a timely manner, and the research proposed a follow -up test optimization plan. From June 23rd to 28th, the Yangtze River Commission organized the second time the Three Gorges Reservoir promoted the ecological scheduling test of the natural reproduction of rafting crooks in the lower reaches of the dam. During the ecological scheduling test, the Yangtze River Commission continued to roll the conference to dispatch the Three Gorges Reservoir according to the water and rain. The outlet traffic of the Three Gorges Reservoir gradually increased from the 24th. Good conditions. The monitoring results show that the ecological scheduling test has achieved significant results.

Since 2011, the Yangtze River Commission has organized 17 times in the Three Gorges Reservoir to promote the natural reproduction test of rafting crooks in the lower reaches of the dam. The year of less than 200 million capsules increased to 8.8 billion capsules this year, which created favorable conditions for the natural reproduction of drifting crooks represented by the "Four Fish" in the middle and lower reaches of the Yangtze River, effectively improving the function of the water ecosystem of the Yangtze River Basin Essence In the next step, the Yangtze River Commission will further study the response connection between the breeding of the Yangtze River fish and the scheduling of water engineering, and jointly establish and improve the ecological scheduling mechanism of the Yangtze River Basin to promote the continuous improvement of ecological functions in the Yangtze River waters. New level.
