Abstract
The interface between the nutrients and cellular processes is referred to as Nutrigenomics. Nutrigenomics seeks to provide a genetic understanding for how common dietary nutrients affect the balance between health and disease by altering the expression or structure of an individual’s genetic makeup. It is the science that examines the response of individuals to food compounds using post[1]genomic and related technologies (e.g. genomics, transcriptomics, proteomics, metabolomics etc.). Nutrigenomics is establishing the effects of ingested nutrients and other food components on gene expression and gene regulation. In fish nutrition, especially for species maintained in aquaculture, formulated feeds are significantly different from the natural diet with recent changes in nutrient sources, especially with protein and oil sources now being predominated by terrestrial derived ingredients. Additionally, many feeds are now incorporated to health management and termed functional feeds, which are believed to improve fish health, reduce disease outbreaks and/or improve post-infection recovery. Using new omics technologies, including transcriptomics, proteomics, and the metabolomics, nutritional requirements and research could be improved to the subsequent level in fish nutrition.
