TyW -- I'm not sure how much choice you'll have on some of these timings for stockings. You'll have to take the small fingerling walleyes when they are ready at the hatchery. Generally, most culturists will stock fry into fertilized ponds, and then harvest the small fingerlings when the zooplankton crashes. This occurs long before the LMB fingerlings are available in the north country.
I suggest a minimum of 500/acre of the small bluegill fingerlings. Many people go up to 1000/acre. The idea here is to stock a strong initial year class of bluegills so their first spawn will only have food and room for a "moderate" strength year class. That gets the bluegills off to a good start. It probably will take about 5 years to get a good number of the bluegills over 8 inches. Even with fast bluegill growth, it takes time to produce the big ones.
