Application of single-nucleotide polymorphism (SNP) as a molecular marker in the study of genetic diversity of aquatic populations

Genetic diversity is one of the important and essential characteristics of any population for its survival. The study of genetic variation in different populations of aquatic organisms is of particular importance in order to protect, stabilize and manage their stocks. Based on studies conducted in recent years, molecular markers have proven that they can be used as indicators of the genetic diversity of aquatic populations. Therefore, the necessity of examining genetic variations in various aquatic species has led to the use of molecular markers in many ecological studies. The present study was conducted to investigate the role of molecular markers, especially single nucleotide polymorphisms (SNP), in the study of genetic diversity in aquatic organisms. The findings can be valuable for the conservation and sustainable management of aquaculture stocks in fisheries and aquaculture.
