A reminder to never release any pet fish into a river, stream or lake. 
 
ROBBINSDALE, Minn. — Creatures of the night vary at Crystal Lake in Robbinsdale, and on Tuesday night going into Wednesday morning, the party included humans.

Jordan Wein and his team from WSB, an environmental consulting firm, geared up for the hunt. They put on waders and sprayed themselves down with bug spray.

"It's kind of like an arms race with these guys," Wein said. "They come up with a strategy to avoid what we have, and we come up with a new strategy to outsmart them in a different way."
