平陆运河进行时 | 青年枢纽鱼道正式投入使用

Core Viewpoint - The establishment of the Youth Hub Fishway is a significant step towards creating a "green project" for the Pinglu Canal, aimed at facilitating fish migration and enhancing aquatic ecological stability in the Qinjiang River basin [1] Group 1: Project Overview - The Youth Hub Fishway is set to be fully completed and accepted by April 2024, featuring an innovative intelligent monitoring system that has recently begun operation [1] - This fishway is the first of its kind in China, designed specifically for the tidal river section to address the migration needs of fish in the Qinjiang River basin [1] Group 2: Design and Features - The fishway employs a dual-channel design consisting of a "vertical seam type + eel passage," which specifically caters to the migration requirements of various fish species [1] - The vertical seam fishway spans 487.4 meters, equipped with 120 chambers and 3 resting pools, facilitating the migration of species such as the red-eye trout and carp [1] - A dedicated eel passage features a 15° sloped water channel combined with a plastic climbing substrate, making it the first specialized passage for climbing fish and crabs in China [1] - The project incorporates innovative "plum blossom pile" bottom structures and 45° diversion angle baffles to ensure efficient passage for fish of different sizes [1] Group 3: Ecological Impact - The Youth Hub Fishway reopens a migration route that has been blocked for over 60 years, significantly contributing to the stability of the local aquatic ecosystem [1] - Since the monitoring system's operation, sonar devices have recorded 1,025 fish migrating upstream and 966 migrating downstream, with water level, quality, and flow rate data remaining normal, thus providing technological support for safe fish migration and ecological balance in the river basin [1]
