SHHH! Its dark. There is a wolf under the ice. You have a spear.
In many states darkhouse spearing is legal.
Darkhouse spearing consists of a 'decoy' that is suspended in the clear water and when a fish comes up to see the decoy-you spear it.
A large hole is needed in order to spear the fish and you will need a fishing house that is completely dark. (Hence the term, "Darkhouse".)
After you first enter a darkhouse it will take a few moments for you eyes to adjust to the darkness.
When it does, get your decoy down the hole and get your spear ready.
Darkhouse spearing is usually used to target Northern Pike,
although other species are sometimes targeted depending on that state's regulations.
