I think we've discussed this before but I'll ask again. If the lake in question doesn't have any signs posted and the fishing regulation doesn't specify a size limit can one just assume that the wiper has to be 15 inches in order to be legally kept? I ask because in this particular lake they looked almost identical to the white bass. The only way to tell for sure was to open their mouth and verify one or two patches on the tongue. And of course the size difference. You can clearly tell when the wipers get above17 inches that they are not white bass.
