Nature has ways of species getting together. If paired adults were removed from a nest that produced fry, it would be extremely rare to not have 0.5%-10% survive to maturity. 0.5% of 5000 is 25 fish. Survival is an instinct for even fish. BG can become mature at 1 yr old. Numerous things will affect survival rate.
In my experience the biggest negative to TJ's YP are the LMB. YP have to survive a long time before a 16" LMB cannot eat them at 8"-9" long.
Despite research that says YP eat YOY 1" BG in winter, IMO it is not near enough predation pressure for controlling BG overpopulation.
WE will not grow well on a diet of BG due to optimum forage theory is not in the WE's favor. They have to eat too many to stay fat and growing.
