About 20,000 dead fish and mussels have been found on the western coast of Canada's eastern province of Nova Scotia, the Canadian department responsible for fisheries has said.
The environmental agency added that it was also testing the water for pollution, as well as the water's oxygen levels to find out why the fish and mussels died.
"At Savory Park between Gilbert's Cove, there were approx. 15,000-20,000 dead herring, a lot of Blue/Red mussels, mostly shells," the department said on its Twitter account on Thursday.
According to CNN, mass fish deaths have been recorded in the US state of Florida and China's Hainan province earlier in the year.
