Xinhua News Agency, Canberra, June 25 (Reporter Bai Xuyue Dongxing) The Commonwealth Scientific and Industrial Research Organization of Australia issued a communiqué a few days ago, stating that its researchers have developed a new DNA (deoxyribonucleic acid) detection technology that can determine the age of fish.
The researchers said that traditionally the age of bony fishes is generally determined by measuring the increment of calcification structures such as otoliths.
Based on previously discovered age-related DNA methylation sites in the zebrafish genome, the researchers determined the age of three endangered freshwater fish, including barramundi
Researchers said that understanding the age of fish is very important for species protection, which helps to understand the growth and reproduction of fish, formulate sustainable fishing methods, and determine whether species is at risk of extinction
