University biologists say striped bass that recently washed ashore in northern Cape Breton probably died from a sudden temperature change in the ocean. A video posted to the Port Morien Wildlife Association's Facebook page on Monday shows what looks like hundreds of dead fish in North Bay, near Dingwall, N.S. Trevor Avery, a biology professor and lead researcher with the Striped Bass Research Team at Acadia University in Wolfville, N.S., said he doesn't know for sure what happened.
