The 20% cover philosophy resulted from research on a BG-LMB fish community with submerged vegetation as habitatcover. Other types of fish communities may benefit from other percentages of bottom cover. The type of cover/habitat, its density, fluffy versus course, the amount, and species involved all may affect the beneficial nature of the cover. Cover is not just fish avoiding predators but also food production - food web potential relating to diversity of habitat. Considering prey and predator behavior the 20% coverage would be close to optimum.
