The problem with waiting until the second year to stock any predators is the potential to have a stunted BG population which will eat small 2in LMB and could greatly impede any later LMB spawn to the point of no recruitment. It is a balancing act. Of course you can avoid this by stocking larger predators the second year but you have to put in enough to get rid of the BG overpopulation or the LMB spawn will be very low if at all. Also if you put in enough larger LMB to do the job, once they have reduced the stunted BG then they are short on food.

I like a lot of initial forage (heavy with various types) and to initially under stock LMB by 30%. I am not brave enough to wait till year 2 to stock LMB predators as that is difficult to do and have good results. I think a better approach would be to put part of your initial BG in as 3-5in BG at the start (along with the other fish) and reduce the #s of 2in BG some. This way you have the 3-5in BG spawn in mid summer and the new LMB can feast on the yoy and FH with out impacting your initial forage base while it gets established. The following spring before the BG spawn you will already have 3 year classes of BG ( the initial 3-5in. ones now 6-7in, the first 2in ones now 4-5in and the remaining first year yoy now 2-3 in.) and well fed one year old LMB able to spawn. This may not work well in Northern ponds as you can't be sure of LMB spawning at one year of age.
