Thanks for the advice, Jan and all. I'll add the salt tomorrow. Once
the microscope gets here, I'll post my findings with that and go from
there.

Is it enough to catch a random fish and do slide scrapings from that
or do I need to check multiple fish and also look for critters in the
water?

Sick ones are best, if flukes your best bet is to take a small gill snip.
For skin scrapings, go under the chin & behind the gill plate.

If you can't get to a sick one, I'd do more than one random fish.... but
you may have flukes that are only in the gills of the sick fish. ~ jan
