“…In 2017, at least 858 species in 81 families were listed, up to 70 species of which were from unidentified taxa, while at least 137 species were threatened (Vidthayanon, 2017). Human activities often affect biodiversity, causing degradation or loss (United Nations, 1992), including of genetic diversity (Nguyen et al, 2022). Sustainable development is a process for resource management and sustainable utilization.…”

The purposes of this research were to identify fish species using DNA barcodes or partial sequences of cytochrome b (Cytb) and to assess the diversity of fish in the Mae Tam reservoir, Phayao province, Thailand. Fish samples were collected 3 times, during the winter, summer, and rainy seasons, from 2 sampling sites using gillnets with 3 mesh sizes (30, 50, and 70 mm). A total of 34 representative samples were classified into 12 species, 7 families and 6 orders by morphological-and DNA barcoding-based identifications. However, one cichlid species, Cichlasoma trimaculatum, could only be identified using DNA barcoding. Family Cyprinidae had the greatest diversity, 50.00%. The diversity, richness and evenness indices ranged from 0.43-0.65, 0.64-1.46, and 0.27-0.40, respectively, indicating that fish diversity at both sampling sites was relatively low. A comparison of the catch per unit effort (CPUE) with 3 different mesh sizes found that the 50 mm mesh size was the best (474.80 ± 171.56 g/100 m 2 /night), followed by the 70 mm (417.41 ± 176.24 g/100 m 2 /night) and 30 mm mesh sizes (327.88 ± 115.60 g/100 m 2 /night). These results indicate that DNA barcoding is a powerful tool for species identification. Our data can be used for planning the sustainable management of fisheries resources in the Mae Tam reservoir.
