A spokesperson for the Canal and River Trust is unaware of why dead fish are in the canal but said they will monitor the area.
A Canal and River Trust spokesperson said: "It's always upsetting to see dead fish in the canal and would urge anyone who spots fish in distress to call our emergency number on 0800 47 999 47 or the Environment Agency on 0800 80 70 60.
"We don't know why a few dead fish were spotted along the canal in Worcester.
"It appears to be an isolated incident.
"Our teams will be out monitoring the canal over the next few days to ensure there is no pollution issue along the canal."
In 2023, hundreds of dead fish were found within the Worcester to Birmingham Canal due to falling oxygen levels.
At the time, pumps were installed to try to resolve the issue, as high heat and humidity reduced oxygen in the water.
The situation had become worse after a sudden thunderstorm.
It was believed that 700 fish had died in the incident between Blockhouse Lock 4 on the Worcester and Birmingham Canal.
Worcestershire Wildlife Trust said it is not best suited to comment on the situation.
