Clupeonella muhlisi is a species of clupeid fish endemic to Lake Uluabat in Turkey, linked to the Sea of Marmara.

[2] It is a small fish, up to 8 cm in length, that shoals at the water surface.

It feeds on pelagic crustaceans and fish eggs.

[2] This population of sprat has previously been considered either conspecific with Clupeonella abrau that inhabits Lake Abrau, Russia, near the northeastern Black Sea coast, or a distinct subspecies of that species, Clupeonella abrau muhlisi,[3][4] or a population belonging to the more widespread Black Sea sprat (Clupeonella cultriventris).
