This winter we are adding 1.5lb Northern Bass to our already stocked lake. The last stocking was 10 years ago with F-1's and we wanted to add "new life" to the population. Our current slot limit is 15" so I need to try and find comparison photos of the Northern vs the F-1 so I can send to our fishermen so they will not be removing the Northern by mistake. Can someone provide me with either the photos or an address where I might be able to get this? Guess the main question is are we going to be able to tell the difference?
