Bismarck, N.D. (AP) North Dakota's darkhouse spearfishing season is underway on most state waters. The season opened Monday and runs through March 15th. Legal fish are northern pike and nongame species. Darkhouse spearing is allowed for all residents with a valid fishing license and for residents under age 16. Nonresidents may darkhouse spearfish in North Dakota if they're from states that offer the same privilege for North Dakota residents. Anglers who take part in darkhouse spearfishing must register with the North Dakota Game and Fish Department prior to participating.
