No you're right, anglers take more pike than the spear guys. I cant argue with that
but the spearing on kabetogama has changed the size sructure.
I can agree that spearing has been blamed for changing the size structure. But it is actually both methods that share the blame. Darkhouse spearing plays it's part in changing the size structure. That part is a small percent of the total winter and summer take of pike (large and small).
It is not the method of taking pike that is the issue; the problem is with the sportsman. They are the ones who throw the spear or keep the caught fish. It is a simple fact that sportsmen prefer larger pike, no matter the method of taking northern pike. (most studies quantify a large northern somewhere between 20 and 24 inches)
Education can help turn these statistics around. All sportsmen should practice and promote Catch and Release and Look and Release. If you want to eat some fish, good. Take the smaller ones and let the big ones live another day. Only take what you need and respect the daily/possesion limits.
I personally am in favor of protective slots; as long as they don't effectively ban darkhouse spearing or other methods of enjoying the resource.
I hope anglers and darkhouse spearers can work together to find ways to make it work for both methods. Much like the laws for rifle, bow and arrow, shotgun, and muzzleloader work for the deer hunters. There is enough room out there for all of us to enjoy our respective sports on these great public resorces.
Right now with regards to darkhouse spearing the slot limits need some work.
