Here's an article that explains the same thing Tubedude mentioned about the fish starving. And it was a harsher winter than we've had in a long time. Just a thought.

Area anglers began reporting dead perch approximately 10 days ago. Fishery experts estimate as many as 3,000 perch may have died. The lake also is a popular angling destination for rainbow trout and smallmouth bass, but the die-off was limited to yellow perch and appeared to mostly affect male fish.
District Fish Biologist Todd Alsbury said examination of the dead perch found all had empty stomachs, likely the result of prolonged cold temperatures in the lake this spring that inhibited natural food source production when the fish normally would have been feeding heavily just prior to spawning.
