Abstract
As a major source of "blue food" Selective breeding offers enormous potential to improve important commercial characters and increase commercial efficiency in aquaculture by providing cumulative and permanent genetic improvement of farmed species. Compared to traditional genetic improvement strategies, molecular markerassisted selection (MAS) rapidly screens for dominant formations within a population by locating genetic markers that are closely linked to the target trait, which greatly saves time and economic costs to increase breeding efficiency During the past few decades, better molecular markers, sequencing techniques and breeding algorithms mean that the mapping of specific genetic loci for economic characters is more efficient and precise. In particular, the advent of high-throughput sequencing technologies has greatly facilitated the rapid development of genomics and molecular biology to analyze the biological and genetic background of quantitative traits, so as to promote the application of aquaculture molecular breeding. The aim of this Research Topic is to collect latest molecular breeding model and/or high-quality research finding on aquaculture genetics and genetic breeding. At present, the Research Topic has collected twelve articles, which are groups in seven different themes (Table
