Population genetic structure revealed by a school of the freshwatermigratory fish, Brycon hilarii

It is believed that different genetic populations of migratory fishes can co-exist in a single hydrographic system. Although different populations may occupy and explore the river together, they segregate during the spawning season and consequently the population genetic structuring is maintained. G...
