I was interested in the amount being fed in ponds with a more normal or ideal populations. Mine has a LMB overpopulation for 20 years with an under population of forage fish. All LMB caught have a RW of 75% or less. The 2# that I throw at night disappears in 5 minutes, but the large male tilapia, grass carp, & turtles get their share. I suspected that I have a bream population that is smaller than ideal. What I see when I feed confirms this. Grass Carp just Hoover it in.
