As a guess I think for the bass to stabilize at adult size the current 2019 LMB crop will have to grow to the 10-11" size so for in an Ontario trout pond it could take 3-4 years. I doubt the 2019 LMB group will be big enough to spawn in 2020 when in June the should be around 5"-6". However if you don't remove the current 3 adults you would get another year crop of baby bass (2020) next May early June. These 2020 bass fry - fingerlings will feed the 2019 bass to get them growing to the 7"-8" size. Then they could spawn in 2021 when some of the 2019 individuals are 9" maybe 8". Expect the 2019 bass to grow to 10" to maybe 12" in 2022. Let's see how far I miss the progress of your fishery.
When the bass get to 10"-12" you can still add trout do diversify your fishery. The supplimentally stocked trout should be a minimum of 7"-8" for good survival to avoid bass predation by 12" bass.
""2. How many bass should I pull each year if I want them to be bigger?"" Assuming that you have 70 bass in one acre, I think to get the remaining bass to grow beyond the 12" you should remove at least 35 and better 45 bass per year or add yellow perch with 25-35 bass ( any size) harvest each year to provide growth & food for the bass. Plus you could harvest some yellow perch for table use.
In my experience with YP in a LMB pond one should remove every bass caught to produce the better quality yellow perch fishery. LMB are intense predators of YP.
