If diaphanus is in trouble, you have a real problem! One way to look-in-
population status is to look for young-of-the-year. With diaphanus you
should find them in shallow water in emergent population. They look like
tiny versions of the adults, maybe not as darkly banded. You could do
size-frequencies of collected YOY to see if you find evidence of cyclical
pulses of breeding (i.e., any lunar influence?). With adults, you could look
at some kind of catch-per-unit-of-effort like how many fish are caught in
five seines along a beach, or some other effort. You could even look-in-
available sandy bottom versus muddy bottom as that might affect diaphanus.

There have been studies done in New England examining the effects of
introduced basses on native shiner populations. Not surprisingly, most
shiners have declined in the face of an introduced top predator. It would be
interesting to compare diaphanus in ponds with and without bass, but I
suspect all local ponds would have bass in them.

If the scouts even know what diaphanus is, that's a pretty good start too!
