Everyone should note that there are differences in stocking north to south. For example one successful method up north is to stock FH and LMB and then up to a year later stock BG. Another method is to stock 2 inch BG in summer followed by 2 year old LMB the next spring. These methods are not used in the south. In addition often the recommended stocking ratios are different as CJ noted. A review of the archive on State Agency manuals will help.

When small bass and bluegills of the
same age were stocked simultaneously in
Alabama, balanced populations always
resulted. When this stocking strategy
was followed in the North, the result
nearly always was a stunted bluegill
population and a bass population
unable to spawn successfully. Research
at Cornell University showed that to
achieve successful bass-bluegill populations
in northern states, the initial
stocking must consist of bass that are at
least 1 year older than the bluegills. This
can be achieved by stocking yearling
bass 1 year ahead of yearling bluegills or
combining 2-year-old bass (over 6
inches) with yearling bluegills less than
2 inches long. Researchers currently
believe that the proper number of
fingerling fish to stock is 100 bass and
200 to 500 bluegills per surface acre.
This stocking strategy has been shown
to be successful in Pennsylvania ponds.
