Pesticide runoff suspected in latest case of dead fish in PEI river Add to ...

For the third time in three years, dead fish have been spotted rising to the surface of a brook in western Prince Edward Island.

The province’s Agriculture Department is trying to determine what happened at Barclay Brook, where thousands of fish died in 2011 and 2012 after pesticides from farmers’ fields seeped into the water.

Government spokesman Wayne MacKinnon says pesticide run-off could be the cause of the latest fish kill. Water samples collected on the weekend have yet to be tested.

“That’s probably a good supposition, although we don’t know for sure,” he said in an interview. “Certainly, not enough effort has been made to contain runoff — if that in fact is what the case is here. We’ve expanded buffer zones and worked with producers in the area to identify some practices to be mitigated.”

Mr. MacKinnon said the problem could be traced to the increased prevalence of severe weather. He said PEI experienced heavy rainfall on Friday, the day the fish kill was reported.

In all, about 100 dead fish were spotted in the brook, which flows into the Trout River near O’Leary.

Mr. MacKinnon said it is unlikely more dead fish will be spotted in the days to come.

“They get consumed fairly quickly or washed out to sea,” he said.

In July, 2012, about 2,000 dead fish were scooped out of a three-kilometre stretch of Barclay Brook near Coleman, and a much smaller fish kill was reported from the same area in 2011.

Environmentalists and sport fishing groups have complained about the problem for years.

“It’s disappointing, but quite predictable,” said Peter Bevan-Baker, leader of the provincial Green Party. “With the rain that we’ve had, all of the dots add up and point towards it being a pesticide problem.”

Mr. Bevan-Baker said legislation requiring buffer zones between waterways and farm fields is not working, adding that the real problem is the excessive use of pesticides.

“We need to become less reliant on food that require poisonous chemicals in order to grow,” he said. “The heavy, sudden rainfalls and the unusual climatic things that are happening perhaps suggest that the measures that may have worked in the past are no longer up to the job.”

The Sierra Club of Canada has said the use of pesticides on the Island should be reduced and that the province should better enforce buffer zone regulations.

In September, 2011, PEI farmer Avard Robert Smallman was fined $3,000 after he pleaded guilty to farming within 200 metres of a watercourse boundary without the protection of a grass headland.

The violation was discovered when Environment Department officers were called in after fish kills in the Trout River, Big Jacques River and Mill River. Environment Canada confirmed that it found traces of a pesticide in bottom sediment in the three rivers.

In July, 2010, dead fish were discovered along a two-kilometre section of the Montrose River in West Prince area.

Three years earlier, fish kills were reported after heavy rain along the Dunk River and Tryon River. Investigators were never able to determine the cause, but several farmers were cited for violating PEI environment rules.
