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.

The objective of this research travel grant was to develop Australian Seafood CRC PhD student Shan He's professional knowledge of transferring laboratory-scale results to a pre-commercial food model for industry benefit, and also build his professional skills and industry experience.

After one and half year's research, Shan He has achieved outstanding scientific outcomes. However, these results have not been applied to an industrial application because of the limitations of the biotechnology laboratory at Flinders University in formulating food products, and in the knowledge of the industry partner's food process and formulas. This research travel grant supported Shan to apply these results to commercial food formulations in a one month industry visit to Simplot Australia, the project's industry partner. The trial activity and industry interaction will train Shan He to be an industry-ready PhD graduate in the near future, so as to be able to better serve the Australia seafood industry.

Shan He was able to conduct experiments talk to managers of different divisions in Simplot Australia related to science, such as the New Products Process & Portfolio Manager, Science & Technology Manager, Group R&D Manager etc. Through these talks Shan He was familiarised with a key decision making system of Simplot Australia called the Stage Gate System. The information that Shan He gained from the communications developed his understanding of the role of science and technology in industry. The outcomes of this project assisted in developing Shan He's professional knowledge of transferring laboratory-scale results to industry products, built his professional skills and industry experience, and thus successfully prepared him to be an industry-ready PhD graduate in the near future.
