Swingle mentioned stocking too few LMB can result in more recruitment. He suggested this was caused by too little cannibalization of LMB YOY. At the time of the publication, the procedure for stocking was simultaneous stocking of fingerlings. Your situation is different as you have allowed the prey to build up to very strong numbers prior to introducing predator fish. A BOW with strong numbers of intermediate sized BG can greatly inhibit LMB recruitment leading to rapid growth and even in some cases no LMB recruitment.
It's its not uncommon to see trophy management plans that incorporate lower stocking rates of LMB than Swingle would have recommended. Their success, depends on the inhibiting effect of BG on LMB recruitment and so requires large enough population to of BG to get that job done. Of course other measures can be taken as well. But no matter how little LMB recruitment you get, eventually they will grow large enough and lower the numbers of BG enough to begin succeeding with recruitment.
It really depends on your goals, but stocking 50/acre isn't to few and the growth should be remarkable. But were I the owner of such a BOW interested in trophy water, I would not slack on culling the male LMB beginning the first Fall. By the second Fall, even if you had removed all the males, the remaining females would be at the verge of outgrowing the BOWs production. You might have an LMB standing weight of 100 to 125 lbs/acre by then weighing between 4 and 5 lbs per fish.
