Walt you made my point. It depends on the pond. The chart tells the story - in half of the 12 studies addressing the effect on BG by shad 6 were positive to neutral and 6 were negative to neutral. But more important are the statements that blanket generalizations were not possible.

The study with LMB , BG and TShad in ponds stated " Bass were in better condition after shad stocking while no change in the condition of bluegill and redear could be detected. I can only find the links to the 2 Abstracts but I have those studies elsewhere.

Yes zooplankton #s were reduced in Stonelick lake but look at the authors conclusions about that :

"Consequently,

although competition between young-of-year

bluegills and young-of-year threadfin shad may

occur (particularly during August in Stonelick

Lake), the outcome of such interactions in a lake

ultimately depends on abundance and species

composition of the zooplankton community and

on the relative spawning times of the predator

fishes. As demonstrated by our results, these factors

vary among lakes and years, making generalization

difficult."
