A researcher noted that in many small ponds fish species A

A researcher noted that in many small ponds fish species A preyed on several smaller species, B, C, D, E, and F. She suspects that species A might be a keystone predator in the pond communities. What kind of experiment could you suggest to test whether this hypothesis is valid? If A is a keystone predator, how would you expect the experiment to turn out?
