Top Thickback Soles Not Elsewhere Included Fishing Countries

Thickback soles, grouped under the "Not Elsewhere Included" (NEI) category in fisheries statistics, refer to various species of flatfish in the Soleidae family, primarily found in the eastern Atlantic and Mediterranean waters. These demersal fish are characterized by their oval, flattened bodies and are prized for their delicate, mild-flavored flesh. The top countries harvesting NEI thickback soles are predominantly European, with Spain, Italy, and France leading the catch due to their extensive Mediterranean and Atlantic coastlines, established fishing fleets, and strong culinary demand for flatfish. These nations utilize both artisanal and commercial trawl fisheries, often landing thickback soles alongside other sole species. The fishing industry for thickback soles is significant in these countries, supporting local economies and traditional seafood markets, though catches are closely monitored to ensure sustainability and prevent overexploitation of these valuable demersal resources.
