I noticed the stocking report of brookies for Henry's lake in 2012 and 2013 was about 100k and 40k. I was wondering if these stockings included male brook trout? I know there was some discussion about this, but never heard whether it was/did happen.


Yes, but...... The only brook trout we presently stock in Henrys Lake are sterile and can't successfully reproduce.  Their are still some natural brook trout in Henrys that migrate up the tributaries in the fall and spawn but survival of the eggs is poor.
By placing eggs in a pressure chamber shortly after fertilization, we can produce fish that can't successfully reproduce (3n).  This allows them to put their energy into developing body mass and allows them to stay in a lake or reservoir for a longer period of time and be available to anglers.
