That was a good question and a good find Tums.

I will add that referenced post that subsequent studies show that purely feed trained LMB put into an existing pond with fish including LMB who also eat natural prey , don't fare as well (they don't compete well). A better method is for the hatchery to feed train the LMB and move them for a time to a pond with forage as well as pellets. Studies show those LMB can compete with existing LMB.
