Research background

Professor Alexander Chong has over 25 years of aquaculture research experience, focusing on the nutrition and metabolism of fish and crustaceans. His expertise includes investigating nutritional requirements, evaluating novel feed ingredients, and studying species’ responses at physiological and molecular levels. He is particularly interested in polyunsaturated fatty acids and their biosynthesis, becoming a leading authority on comparative biosynthesis pathways in teleosts and crustaceans. Alex serves on editorial boards for Reviews in Aquaculture and Aquaculture Research, and is Chief Editor for Tropical Life Science Research. He also works with industry to address feed quality issues in various species.

Research focus

Lipids and Fatty Acids, Feed Development, Sustainable Aquaculture
