An investigation into risk factors associated with disease in Barramundi Aquaculture production

Xian Zhe’s interest in fish health began in James Cook University Australia where he volunteered in the Marine Parasitology Laboratory, run by Dr Kate Hutson. After completing his undergraduate studies, he worked in Singapore’s aquaculture industry, helping out in fish health management and husbandry. Currently, he is pursuing his PhD at JCU Singapore where he is interested to find out how, when and why disease occurs during barramundi production. He hopes that the findings of his study will help boost the local barramundi production in Singapore and the aquaculture industry. #RiskFactors #Aquaculture #Barramundi #Disease #Singapore

Life history, ecology and fisheries impact on the blackspot shark, Indonesian whaler shark & bluespotted maskray: Implications for conservation and management.

Naomi is a current PhD student at JCU Singapore campus. She is studying the life history, ecology and trade of small-bodied sharks and rays in Southeast Asia, with focus on the Indonesian whaler shark (Carcharhinus tjutjot) and blackspot shark (Carchahrinus sealei). Since 2017, Naomi has led an independent project collecting data from Singapore’s fishing ports on the sharks and rays imported from the region for their meat. She has a BSc in Animal Behaviour from the University of Exeter (2012), and an MSc in Marine Science from Plymouth University (2013).

Nutritional requirement study and optimised feed development for Red Snapper

Shawn’s passion for aquaculture started back in 2012 where he was involved in several aquaculture genomic research in Temasek Lifesciences Laboratory, led by Prof.  László Orbán. He has also worked at Singapore Food Agency (SFA) where he has contributed to the establishment of the pilot aquaculture feed mill facility at Marine Aquaculture Centre. Currently, he is pursuing his PhD at James Cook University Singapore (JCUS) with SFA’s support to study the nutritional requirement of food-fish species. He aspires to become an aquaculture nutritionist with the know-how to develop optimal and cost-effective feeds to help improve the productivity and sustainability of the local aquaculture industry.

Developing genetic resources for Malabar red snapper and establishing the first breeding program

Liang Bing’s interest in aquaculture began in 2009, when he started to work on the development of aquaculture technology at Marine Aquaculture Centre of Singapore Food Agency (SFA), with focus on managing a selective breeding program for Asian seabass. Currently, he is pursuing his PhD at James Cook University Singapore with SFA’s support to study the application of genetic technologies for the improvement of farmed aquaculture species. He hopes to deepen his knowledge and expertise in aquaculture genetics to help the local aquaculture industry improve the productivity and sustainability.

Investigating the Pathogen-Host-Environment Relationship Of Scale Drop Disease (SDD)

Jeffrey is a current PhD student at JCU Singapore campus. He is investigating the pathogen-host-environment relationship of Scale Drop Disease in Asian Seabass. He is hoping that his research will uncover information about how the disease progresses and how it spreads so that it may be applied in future studies, such as treatment and vaccine trials. He has a Bachelor of Veterinary Science from Massey University (2013), a Master of Science from the National University of Singapore (2020), and a Master of Public Health from the University of Aberdeen (2022).

Understanding protein differences to make healthier and safer seafood

Afifah is pursuing an MPhil in Health at JCU Singapore under supervision of Professor Andreas Lopata and Dr. Thimo Ruethers. She is studying the differences in protein content between various fish with a focus on allergens - proteins triggering allergic reactions. Allergies to fish and shellfish (seafood) are a major and growing health concern. Understanding protein differences will guide food innovations (e.g., cell-cultivated meat) in producing healthier and safer seafood. Afifah holds a Bachelor of Business and Environmental Science majoring in aquaculture from JCU and gained experience as a research assistant with the Tropical Futures Institute in animal health and diseases.

Genomic selection of barramundi (Lates calcarifer) for improved scale drop disease virus (SDDV) resistance, growth, and fillet traits

Josiah’s focus for his PhD research is on the genetic improvement of barramundi. This follows a natural path from his Bachelor of Business and Environmental Science (Majoring in Aquaculture) and Graduate Diploma in Research Methods as he follows his life-long fascination with the natural world and dream to become a scientist. Through his research, Josiah aims to develop more productive, resilient, and sustainable strains of barramundi through the use of advanced genomic tools. By understanding the genetic basis of favourable traits in commercial aquaculture, he hopes that his research will increase productivity and profitability for farmers while building a more sustainable food system.
