there is a guy that works for me that was charged by a moose while deer hunting, he shot it, then reported it, was fined with shooting a moose out of season even though it was found that the moose was hit by a car, injured, and charging him. they took his license away as well. i would be very careful removing a pike where it didnt belong. head of f and g should address this with the pike or any invasive being caught. whats right isnt always right, be careful
