Yellows Hadn't Spawned Yet?!

Type: Tidal
Region: North Eastern
Location: Northeast River

I went fishing on the Northeast River on 4/2/14 and hooked up with about three dozen Yellow Perch (on the incoming tide with minnows) ranging from skinny 7" up to thick 13"+ Here's the kicker: none of them had spawned yet!! (De-hooking them got a little.. messy. Ick) All were safely returned to start the next generation, guess winter has everything delayed�
