Scientists test water to narrow down what’s killing herring, sea creatures at St. Marys Bay

Federal scientists are testing water samples and scanning images of the bottom of St. Marys Bay, hoping to determine what caused thousands of herring and sea creatures to wash ashore near Digby, N.S. Staff aboard a vessel gathered samples Thursday and used an underwater camera to film and photograph the ocean floor. Kent Smedbol, manager of population ecology for the Department of Fisheries and Oceans (DFO) in the Maritimes, said the data will be examined to try to figure out whether an environmental factor caused the fish to die. “It could be an intrusion of very cold water very rapidly, it could be related to a rapid change in salinity with the storms that have gone through … due to the sudden influx of fresh water, rain or runoff from the land,” he said.  “Depending on what we find, then hopefully that will allow us to discount a number of possibilities and focus our efforts on some possible explanations.”  Read the story here 08:55
