Expensive perch. But it's not really clear to me that fishing for perch (or bass, or blue-gill, or most anything else that is not caught with a downrigger) in Lake Washington is actually a violation of ESA. Seems more like a hyper technical over-reaction by the State. Heck, the WDFW 'how to catch perch' video says catching them is a high priority for resource management. Having more of the buggers in the Lake as a result of a fishing ban may just increase predation on Chinook smolts.
