Top Slender Codling Fishing Countries

The Top Slender Codling (*Halargyreus johnsonii*) is a deep-sea fish species found in temperate and subtropical waters of the Atlantic, Indian, and Pacific Oceans, typically at depths between 500 and 2,000 meters. Characterized by its elongated, slender body and silvery coloration, the slender codling is not a major target of commercial fisheries but is sometimes caught as bycatch in deep-sea trawl fisheries. The primary countries involved in harvesting slender codling are New Zealand and Australia, where deep-sea trawl fleets occasionally land this species while targeting more commercially valuable fish like hoki and orange roughy. Other countries with minor landings include Spain, Portugal, and Japan, mostly as incidental catch. The overall fishing industry for slender codling is relatively small, with limited direct economic importance, but the species is monitored as part of broader deep-sea fishery management efforts to ensure ecosystem sustainability.
