I’m learning heaps at the FRDC conference here in Cairns.
Take for example, skin scrapes. Many text books (including my own book) always instruct taking samples from the base of dorsal fin, under their pectoral fin, and from the caudal peduncle.
From work done on a particular species of fluke in barramundi, Alejandro has shown differences in distribution of this parasite, depending on the age of the parasite.
See pictured, a map of the combined distribution of different ages of flukes on barramundi.
So, in addition to the three standard sites mentioned, an important fourth site is from the ventral aspect of the body.
