The next step in extracting slop bass is to pinpoint specifically where within a bed bass exist. Slop beds regularly vary in size from less than 10-yards in diameter to several acres across. In the case of a relatively small piece of slop there's no science to dissecting it because you can thoroughly cover it with a half a dozen casts or less. But when encountering a massive scum field it pays to have a strategy. The first things to look for are natural edges and transition areas.
Natural edges are merely where the slop breaks off into open water.
For instance, the perimeter of a lily pad field commonly hosts ambushing largemouths. Aggressive bass tend to lie just inside the pads, facing open water, hoping for a snack or two to pass by. Highly aggressive bass might even patrol the outside edge. Other slop ingredients such as milfoil and duckweed offer similar natural edges and they should be treated accordingly. Transition areas within a slop bed itself are other pieces to this puzzle.
