Here the fish are caught by local artisan fishermen as well as by foreign industrial fleets; they may be the targeted species or may be bycatch in hake, cephalopod or shrimp fisheries, but the catch statistics are not subdivided by species. There is also thought to be overfishing in the Black Sea. The fish is currently listed by the International Union for Conservation of Nature as being of "least concern" because it has a wide range, occurs at depths down to 328 m (1,080 ft) and is expanding its range northwards as a result of rising sea temperatures.[1]
