Artenschutz: Protomelas sp. 'oxyrhynchus mix' wurde nicht durch die Internationalen Union für die Erhaltung der Natur (IUCN) in der Roten Liste bedrohter Arten bewertet. P. sp. ‘oxyrhynchus mix’ is a rare species and is vulnerable to being over-fished as it lives in shallow flat-bottomed areas. Since it has been discovered in recent years there is no indication whether it was more common 20-30 years ago.
