Dear Editor,The coexistence of various species in a shared natural environment often results in the differentiation of their ecological niches,as they adapt to specific ecological roles(Jani?ováet al.,2018),this process leads to the development of distinct phenotypic traits and dietary preferences(Li et al.,2021).Studying this adaptive evolution,the four major Asian domestic carps,namely Ctenopharyngodon idella(grass carp),Mylopharyngodon piceus(black carp).
