The Department of Fisheries, Aquaculture and Environment is investigating an incident of fish mortalities discovered Wednesday.
The Department received a report late Wednesday afternoon of dead fish in the upper end of the Wilmot River in Norboro.
Spokesperson Jim Young, Director of the Water Resources Division, said the call came from a member of a conservation group which was doing habitat improvement work in the area of Murphy's Bridge.
Young said investigators collected approximately 200-300 dead fish including sticklebacks and brook trout. Investigators have not yet determined the extent of the incident due to a lack of clarity in the water.
"At this point, we do not know the cause of death. It appears that water temperature and dissolved oxygen were not factors, but beyond that we cannot make any determination until we receive lab results," Young said.
Investigators collected water and sediment samples, as well as dead fish to be sent to the Environment Canada laboratory in Moncton for analysis. It is expected to be a couple of weeks before results are back.
The Department of Fisheries, Aquaculture and Environment is continuing to investigate the incident in cooperation with Environment Canada and the federal Department of Fisheries and Oceans.
