Yellow perch have a lot more personality and difference between individuals than we had suspected,” Aaron Fisk, a professor with the university’s Great Lakes Institute, said Thursday. “It’s neat. One thing for sure, every individual is different. We saw different behaviour, even among the same size of yellow perch.

We noticed two of the yellow perch for long periods of time completely moved in tandem,” Fisk said. “According to the data, they seemed like they were right on top of one another.”
Some analysts even wondered for a time whether one of the yellow perch had eaten the other. It hadn’t.
They moved around in these intricate patterns right together, which was a bit unexpected,” Fisk said. “At one point they stayed right together for about 30 minutes, then they separated for 10 minutes in different directions, and then they came right back together.
