Actually about the only time anyone has been catching crappies on BM is at night for the last month. Also while there is a night bite on WBL it’s been pretty poor lately. Walleye and crappie. Just as an update.
To me a true night bite happens almost an hour after dark-bugs emerge, the bit is on. I’ve fished BM for a long time, clear pressured lake, sunset bite will extend into total darkness-but it does shut off. Things are changing a bit out there though can even catch a keeper sunny out there now.
