The Top Ridge Scaled Rattail (Trachyrincus scabrus), also known as the roughsnout grenadier, is a deep-sea fish found primarily in the Northeast Atlantic, Mediterranean Sea, and parts of the eastern Atlantic off northwest Africa. Characterized by its elongated body, large head, and distinctive ridged scales, this species inhabits depths typically between 400 and 2,000 meters. The fishing industry for the Top Ridge Scaled Rattail is relatively small compared to other commercial species, as it is often caught as bycatch in deep-water trawl fisheries targeting more valuable species like hake and black scabbardfish. The primary countries harvesting this species include Spain, Portugal, and Morocco, with additional landings reported from France and Italy. While not a major target species, its presence in deep-sea trawl catches makes it a notable component of the deep-water fisheries in these regions.
