Thanx for the reply.I thought they were from this year.It has been very warm here now for a while.Water temps are close if not over 70. I never thought about takein the male LMB from the fry so you dont have to much a survival rate. Do the BG males protect the fry like that???I just sank alot of trees and milk crates tied together so the tiny ones will be safe.Fun to see everything clicking when spring time comes.Good fishing to ya
