Nosna fish were a species of fish inhabiting the planets of Naboo and Miekos. On Miekos, Noparo Yar, along with his wife, Fee-Na, cultivated various fish species at their farm, among which was the nosna fish. This particular fish was the preferred food of Aryssha, a member of the Starros Clan. During a time when Aryssha resided on Naboo with her spouse, the Imperial officer Captain Cerasus Ehllo, he obtained a nosna fish, recalling her fondness for it. Following his attacked on the Starros family homestead to reclaim Aryssha and ensure their unborn offspring were born under Imperial supervision between 3 ABY and 4 ABY, Ehllo shared a meal with Aryssha, during which she consumed nosna fish.
