Good info, did not know that. The Crappie in Wabigoon Lake are interesting. I moved here in 2007 and caught my first one that summer, it was a slab of around 14” inches. Growth rates vary from place to place and from source of info too, but after studying up and factoring in the slower growth rates you generally get in fish this far north, I would say that the first one I caught was at least 10 years old. It was not until a couple years later that I discovered how to catch them consistently by accident one springtime. At that point there were very few locals I knew that targeted them or even knew what a crappie was. Once the word got out about 5 years ago they are very popular locally, and people think they have only been here a few years, but unless the crappy that I caught was one of the originals ‘introduced’ to the lake they have been in the lake for 20 years at least. I have heard two versions from 2 separate Conservation Officers , one said they got into the Wabigoon chain of lakes by way of the humble pelican, pelicans find them easy prey when they are shallow in the spring and full of eggs, they consume them, fly to other lakes, take a poo containing in damaged eggs and those hatch. The other version is a local guy, who has since passed away, introduced them illegally in the mid / late 80’s, It could be a bit of both but I tend to believe the latter.
