Chew Xian Zhe


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

Naomi Clark-Shen


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).

Ngoh Si Yan (Shawn)


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.

Liang Bing


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.

Jeffrey Ling Min Than


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).
