Comments: White suckers spawn in Beaver Brook for a few days in mid to late April. Remember to look for them after you file your taxes. Note the reddish stripes on the sides of the males flanking the female in the photo. The female and the males release their eggs and sperm simultaneously, thrashing their tails to mix them and ensure fertilization. White suckers also spawn in Sucker Brook where it enters Lake Massapoag near the entrance to the Community Center.
