Ministry of Natural Resources spokesperson Jolanta Kowalski confirmed that both the MNR and environment ministry were alerted to a massive die-off of gizzard shad fish late last week.
“We think it’s a natural occurrence,” Kowalski said. “They died off as a result of temperature shock because we had that really warm weekend ... and then it quickly cooled off again.”
Kowalski said such die-offs are not unusual but it typically happens in the spring.
Only one species was affected, further supporting the idea it was a natural occurrence, she said.
“There was nothing to indicate that it was man-made.”
