Abstract Aquatic species have become an integral part of human culture. As internationally important food fish species, the common carp Cyprinus carpio accounted for over 7% global aquaculture production in 2020. In addition to serving as a source, varieties are used ornamental and valued recreational fisheries. The continuously updated reference genome has recently served foundation both basic genetic studies evolutionary studies. With recent emphasis on allotetraploid signature carp, researchers begun focus how hybridization polyploidization affect successful speciation advantageous behaviour carp. this review, we survey current emerging research topics including genomic tools, germplasm resources, diversity, mechanism improvement economic traits, well multiple breeding technologies employed We also provide overview trends improvements encourage monitor Understanding basis economically traits mechanisms allopolyploidization will be innovation agronomically although road ahead challenging widely domesticated species.
