Fillipo, a surface acre is 43,560 sq ft. It's easier for us in the US to look at it as the playing surface of a football field or 100 yards x 40 yards.
About 95% or more of those young bass will be eaten by the other bass and the punkinseeds. But, that still leaves way too many for their food supply. It reminds me of Texas. The average unmanaged Texas pond is bass heavy and bluegill light. In other words, too many predators for the food supply. Like you, without heavy culling, we wind up with a bunch of starving, skinny, bass.
