大藤峡水利枢纽工程累计放流近2000万尾鱼苗

Core Viewpoint - The Datiangxia Water Conservancy Project has released nearly 20 million fish fry to enhance biodiversity in the Pearl River Basin [1][2]. Group 1: Fish Release Activities - The project has conducted 26 fish release events, distributing various species of fish fry, including 1 million self-bred fish and 252,000 local species such as Longfin Loach and Yellowfin Goby [2]. - The release also included 900,000 of the "Four Major Fish" (Qing, Grass, Silver, and Bighead Carp), effectively complementing rare species with conventional economic fish [2]. Group 2: Measures for Success - To ensure the success of the release, the project implemented meticulous measures such as strict seed quarantine, oxygen control, temperature management, point-to-point transportation, and the establishment of buffer release slides [2]. - These measures aim to maximize the survival rate of the fish fry and ensure effective outcomes from the release activities [2]. Group 3: Ecological Protection Efforts - The Datiangxia Water Conservancy Project has integrated water ecological protection into its operational responsibilities, promoting technical breakthroughs and systematic protection [2]. - The project has successfully achieved artificial breeding of 11 fish species, including nationally protected species, filling gaps in domestic research and aiding in the optimization of aquatic biological community structures in the basin [2].
