Hog pike man. That lake must be loaded with Whites or Perch in order to make thick fish like that. All the fish pictured look very healthy girth-wise. If that one beast is indeed 43" she may be close to 25+ pounds with a girth like that. Once in a life time fish for most seasoned anglers, and these young pro's pulled it off before grade school was even finished!!
So impressed by your kids but even more impressed by their awesome father / mentor setting such a good example with fish handling and obviously setting them up with the right gear and in the right spot. Those memories will last a life time man thank you so much for sharing. Stories like this are needed when the world seems like such a negative place nowadays.
Cheers!
