Phoxinus grumi is a species of freshwater ray-finned fish belonging to the family Leuciscidae, the shiners, daces and minnows. It is endemic to China.

Genomics

A chromosomal-level genome assembly of P. grumi was published in 2026. The assembled genome has a size of approximately 900 Mb, with 97.6% of the sequence anchored to 25 chromosomes and an estimated completeness of 98.1% based on BUSCO analysis. A total of 24,224 protein-coding genes were predicted, most of which were functionally annotated. This genomic resource is expected to support studies of adaptation and conservation genetics in this species.
