Fishway Reopens 66-Year Migration Path in China
13 Oct
Summary
- A fishway on Pinglu Canal has restored fish migration after 66 years.
- Over 83,400 fish have swum upstream since monitoring began in 2025.
- The facility includes a unique climbing passage designed specifically for eels.
A specially built fishway on the Pinglu Canal in Qinzhou has successfully restored natural migration routes for local fish species, a cycle that had been interrupted for 66 years. The construction of the Qingnian Sluice in 1959 had severed these paths.
Monitoring equipment, operational since 2025, has recorded significant fish activity: over 83,400 fish have migrated upstream, and 122,200 have moved downstream. This corridor has been used by more than 10 species, including barbel chubs and mud carps.
The 480-meter dual-channel facility is a marvel of ecological engineering. It incorporates a vertical-slot fishway and China's inaugural climbing passage specifically designed for eels. Engineers have also integrated resting pools, advanced base structures, and water flow boosters to manage current speeds, ensuring safe passage for a variety of aquatic life.
