| How is a skin scraping prepared? | A skin scrape is prepared by obtaining a small quantity of mucus from the skin surface of a freshly dead or anesthetized fish. Areas of predilection for skin parasites are those adjacent to the fins and it is a good approach to obtain material from these sites. The mucus is suspended in a small quantity of water on a microscope slide (preferably pond or tank water from which the fish was taken; tap or distilled water may destroy the parasites), a cover slip applied, and the preparation examined under the microscope (×40 magnification should be sufficient to visualize most parasites). The second picture shows prepared gill, fin, and skin biopsies. |
