Stocking fewer but larger initial stocker fish like LMB or SMB will work - a lot better than overstocking. Assuming enough forage (if not then don't stock) you will be managing the offspring of the stocker predators not so much the original fish. Fewer original predators moves the date of over reproduction off for a year +-. In addition with larger stocker fish you have better first year growth and less risk with unknown mortality than with 2 in stockers. IMO you need another type of fusion form (minnow) type forage - maybe GSH.
