Specialist teams are currently relocating fish from sections of canal in Bath which is being drained for some essential repairs to the lock walls.
The project, set to last three weeks, is being carried out by British Waterways at Bath Lock Flight on the Kennet and Avon Canal.
Costing £270,000, it will involve completely draining six of the locks on a mile-long section of canal.
The fish will be stunned by the teams and then moved to either side of the drained stretch of canal.
“The fish will be carefully monitored throughout the whole process and once the lock flight is reopened they should naturally swim back to their old habitats.” a spokesman said.
