A fish paternity test is carried out by comparing the DNA profiles of the mother and father to that of their offspring. This test is carried out using simple oral swabs and can be carried out by anyone- the assistance of a vet is not required.

How is the fish parentage test carried out?
Carrying out a fish parentage test is very simple and straightforward. DNA samples are collected by means of oral swabs that are rubbed on the inside of the mouth of each fish participating in the test.
Why test the mother?
Having the mother's DNA makes testing more accurate. A father may be falsely confirmed to be the biological father if the mother's sample is not used. Having the mother's sample helps the laboratory exclude her share in the genetic inheritance of the offspring. When the mother is not available, extended testing can be done to determine proper parentage.
At what age can testing be done?
Cheek-swab samples can be obtained from fishes of any age, even newborns. If babies are nursing, separate them from the mother for about 30 minutes (long enough that they do not have milk in their mouth when you go to swab them).
