Due to the rising demand for human nutrition and a lack of wild fishery resources, aquaculture has experienced a significant expansion in terms of production and economic value over the past few decades. Therefore, sustainable aquaculture production is one of the European Union's top priorities in the 2030 agenda. However, the expansion of fish farming has resulted in an increase in the use of antibiotics to combat illness and a rise in the risk of outbreaks. The selective pressure generated by these drugs creates the ideal conditions for the emergence of antimicrobial resistance hotspots in aquaculture facilities. Refers to a collection of contemporary technologies such as genomics, metagenomics, transcriptomics, proteomics, culturomics, and metabolomics. These techniques have received increasing acclaim because of their capability to decipher novel biological science mechanisms. Metagenomics makes it possible to study microbial genomes in specific environments. In aquaculture, microbial diversity, microbial functions, and antibiotic resistance genes could all be studied with the help of metagenomics. The high-throughput technologies used in aquaculture studies of microbial diversity and antimicrobial resistance will be discussed in detail in this review.
