Once abundant in the Nida River, vimba bream (Vimba vimba) was not detected during extensive electrofishing surveys undertaken in the late 1960s, 1990s, or early 2010s. Irrespective, a few angler records of this species suggested that a small population of vimba bream might persist in the Nida River. Finally, several records from 2015, 2016, and 2017 confirmed its presence in this river system and indicated its successful reproduction in the middle reach of the river.
