It is something that has to be done. Invasive species must be dealt with. If they keep up on it, they can fix the problem. The problem lies in the fact that the process must be kept up or the pike will return. It cannot be a one time shot in the dark. It is too bad that they have to get rid of them though because if you have ever had a northern pike on the end of your line you know how they can fight. Great eating too once you know how to filet them and get the Y bone out of the back.
