This study investigated the distribution of the expression of selected members of the peroxiredoxin (Prx) and glutathione peroxidase (GPx) antioxidant enzyme families in YTK (Seriola lalandi), an important finfish aquaculture species in South Australia.

The purpose of investigating the expression of these enzymes was to determine if they played a role in male fertility in fish, as both these families play a role in male fertility in mammals and individual members of these protein families were shown to be highly conserved between mammals and fish.
