Abstract

The global decline in wild sturgeon populations has led to the implementation of policies to conserve and protect this species. Sturgeon conservation is a major concern today, and actions must be taken in this direction. When discussing this topic, it is important to understand how species adapt to survive in different environments. Studying their DNA is the most accurate method for determining evolutionary relationships among sturgeon species. Molecular genetics focuses on the genetic information contained within DNA molecules that is responsible for the development, functioning, and diversity of all living organisms. Genomic DNA extraction is a fundamental molecular biology technique used in studies of genetic diversity and the phylogenetic evolution of species. In this work, we propose an effective method for extracting DNA from sturgeon fin fragments that were preserved in ethanol and stored in the refrigerator for an extended period of time.
