For the past three weeks, a pair of researchers -- one from the Nature Conservancy, the other a Cornell graduate student -- have been on a frigid mission on Lake Ontario's Chaumont Bay.
"We're here to capture and tag male and female ciscoes with radio receivers," said Mathew Levine, Northern New York field representative for the Nature Conservancy.
Lake Ontario ciscoes Researchers are attaching radio transmitters and tracking native ciscoes in Lake Ontario to see where they spawn.
On Tuesday, the two announced they had finished part of their task. They tagged 15 females that day, in addition to the nine males they tagged previously.
