Editorial: Mining, development, and utilization of genetic resources related to economic traits of aquatic animals based on omics technology

The research on genetic resources of aquatic animals has made significant progress in the past few decades, especially in the mining of functional genes and regulatory networks related to economic traits, which was strongly supported by the mature commercialization of high-throughput sequencing technology, also known as omics technology (Munang'andu et al., 2018;Davey et al., 2021;Martyniuk, et al., 2020). It is efficient to reveal the signal pathways closely related to the development, growth, sexual maturity, neuroendocrine, and nutritional metabolism of aquatic animals using omics technology. We anticipate that in the coming years, many novel and disruptive technologies will apply in the aquaculture industry and facilitate the blooming of research on the genetic resources of aquatic animals. We are happy that many young scientists contributed innovative work to this special issue. As guest editors of this special, we are very grateful to all the authors for their efforts and contributions. We also thank all reviewers for their careful evaluation and valuable suggestions of the articles assigned to them, which made great improvements to these articles. Finally, we are glad to acknowledge Frontiers in Marine Science for always supporting this special issue.
