Top Roudi Escolar Fishing Countries

Roudi escolar (Promethichthys prometheus), also known as black snake mackerel, is a deep-sea fish found in tropical and subtropical waters worldwide. This species is prized for its firm, oily flesh but is also known for its high wax ester content, which can cause digestive issues if consumed in large quantities. The fishing industry for Roudi escolar is relatively small compared to other commercial species, but it is targeted by deep-sea longline and trawl fisheries. The top countries harvesting Roudi escolar include Spain, Portugal, Japan, and Taiwan, where it is often marketed as a delicacy or used as a substitute for more expensive fish such as tuna or mackerel. These countries have developed specialized fleets and processing facilities to handle deep-sea species, and Roudi escolar is typically exported to markets with a taste for exotic or oily fish.
