The warm water temperatures in central and southern Minnesota lakes brought the males in shallow, ready for some action. Many have been stood up by females not quite in the mood yet, their eggs not ready, while other females inexplicably seemed to have dumped their eggs.

The dating scene in the walleye world isn't a whole lot different: There's a lot more flirtation than actual spawning.

The fish are confused by the weather, and so are fisheries biologists, who are trying to gather eggs and sperm to hatch fish to be stocked statewide.

"I've talked to everyone I can think of, guys who have been doing this for 30 years, and all these guys are scratching their heads this year," said Neil Vanderbosch, who coordinates the annual egg-taking program for the Minnesota Department of Natural Resources. "Nobody has much experience with this kind of weather."
