Description
Fengjiao Ma and co-authors report a genomics study from two thousand twenty-five on a fish called Coilia nasus. The species has two forms: one migrates from sea to fresh water to spawn, and one lives its whole life in fresh water. Whether the fresh water form counts as its own subspecies was long disputed.
The team resequenced genomes from twelve populations across three river systems. Their analyses showed the fresh water form is an ecotype of the same species, not a subspecies. It carries slightly more genetic variety and split from the migratory form a few thousand years ago, near the time Tai Lake formed. The study also found genes under selection that suit local life in the migratory form.
