I have been looking into BG populations over the last couple days and here is one interesting thing I learned.
When BG experience high predation young in life they try to grow large quickly and then sexual mature.
If BG experience high mortality through out life then the pressure is to spawn before they get eaten, being large doesn't pay off.

So from a managment perspective the ideal BG growing lake would have a dense predator population to eat age 0 to age 3 BG (0"-4"). But, it would only have limited fishing pressure on the larger fish.
