Advanced Omics Approaches for Deciphering Fish Immune Responses to Microbial Infections

The application of multi-omics approaches—genomics, transcriptomics, proteomics, and metabolomics—has become essential in fish disease studies. These advanced technologies allow for a comprehensive understanding of the molecular mechanisms underlying fish immune responses to pathogens. Omics data can inform the development of vaccines, immunostimulants, and diagnostic tools, offering sustainable solutions to combat fish diseases and ensure a steady supply of fish products. Transcriptomics, using RNA sequencing, has revealed immune-related genes and pathways involved in fish responses to infections. Proteomics studies have identified key proteins involved in fish immune responses, while metabolomics has highlighted crucial metabolic changes during infections. Together, these multi-omics approaches provide a holistic understanding of fish-pathogen interactions and pave the way for innovative strategies to enhance disease resistance in aquaculture, contributing to the global food supply.
