If you do things correctly you should be able to have 2 to 3 3-4 lb bass (17"-19")in 1/2 acre where there are abundant forage fish and not a lot of other smaller bass as predators. I have seen that occur in a few 1/2 ac ponds. Again pounds of fish per 1/2 acre will depend on the pond's productivity - food chain - food web; starting with a good phytoplankton community and/or pellet fed fish. A good fertile pond can maintain around 25 to 35 lbs of bass per 1/2 acre and not so fertile 10 to 18 lbs of bass per 1/2 ac. Those bass could all be single sex population, preferably females.
