Dusky grouper stocks have decreased due to overfishing, prompting the need for aquaculture to help conserve the species, but insufficient biological data hampers efforts.
Researchers used Next Generation Sequencing to analyze liver transcriptomes, confirming key genes related to lipid metabolism and testing the impact of different dietary fatty acids on these genes' expression.
Findings revealed that diet significantly affects hepatic lipid profiles and gene expression, suggesting that specific genes could serve as biomarkers for optimizing diets tailored to this endangered fish species.
