Shrimps are an important part of global aquaculture, especially South American white shrimp and other varieties dominate the global aquatic supply, and their output accounts for more than half of the world's total crustacean production. Growth traits (such as body length, weight, etc.) are directly related to breeding yield and economic benefits, and are one of the core goals of aquatic breeding. In recent years, molecular genetic technologies such as quantitative trait locus (QTL) localization and genome-wide association analysis (GWAS) have made progress in the field of aquatic products and have been gradually applied to shrimp genetic breeding research. This study reviews the main growth traits of shrimp and their biological mechanisms, reviews the current application status of QTL localization and GWAS in the study of growth traits of shrimp, summarizes the research progress of key molecular markers and candidate genes, and discusses the combination of traditional breeding and molecular assistive means using Chinese shrimp as an example. Finally, future strategies and international cooperation in shrimp molecular breeding are expected.
