11) MICROSCOPY – Gill Biopsy
This is just a really good microscope.
So I collect a biopsy from the gills of a Sarassa Comet. My hand is in the way on one. The gills are pale in this box of fish, they are infested with flukes. The wholesaler complains that these flukes show resistance to medications. The flukes are body flukes, liverbearers, Gyrodactylus species. All I find in this group for biopsy is nothing but Flukes.
