I agree with Dr Dave and think there is one primary spawn for northern bgill. I think some of the late season spawns in the northern states are from late maturing females and not a second "full" spawn for that female. For twice spawning fish in the "north", I think some females may not lay all eggs at first spawn and some or a percentage are laid later in the season. I have no proof of any of this just my thoughts and observations. I will be very interested to see the real scientific evidence on this topic for, esp northern bgill. Results will probably be VARIABLE. I do believe in two or three spawns for bgill that live exposed to long growing seasons.
