==Procedure==

Choose the area that is to be sampled. It is best to scrape the '''periphery of any obvious lesions''' as this is where parasites tend to congregate and tissue is healthiest. '''Several samples''' should be taken from different regions as parasites can be very difficult to find.

==Skin Scraping in Fish==

==Skin Scraping in Fish==

When taking skin scrapings from fish, only the '''mucus''' is sampled; the '''epidermis should not be broken'''. A '''blunt metal or wooden scraper/spatula''' should be used and the mucus placed onto a slide with a small amount of '''tank/pond water''' (chlorine and other minerals in tap water may kill any parasites present). The slide can be interpreted in the same way as those from mammals. Fish may be sedated for the procedure if required to prevent damage or injury.
