Genetic diversity and population structure of Pseudobagrus ussuriensis (Bagridae, Siluriformes, Actinopterygii, Osteichthyes) revealed by integrative analysis of mitochondrial genes and GBS-derived SNPs.

ABSTRACT:

Background

Global freshwater fishes face multiple pressures, including habitat degradation, overfishing, and environmental pollution, leading to a continuous decline in genetic diversity. Ussuri catfish (Pseudobagrus ussuriensis, Chinese common names: Huangziang and Niuweiba) is an endemic Chinese species of considerable ecological and economic importance. Declines in population size and degradation of wild stocks have raised significant conservation and aquaculture concerns. To promote the effective conservation and sustainable use of this species' germplasm resources, we analyzed the genetic diversity and population structure of 149 individuals from three wild populations and two cultured populations using mitochondrial genes (Cytb and COI) and genotyping-by-sequencing (GBS) data
