Dagetichthys lusitanica, commonly known as the Portuguese sole, is a species of flatfish native to the eastern Atlantic Ocean.[1] Little is known of the abundance or behaviour of this fish, and the International Union for Conservation of Nature has rated its conservation status as being "data deficient".[1]
Description
The Portuguese sole grows to a standard length of about 35 cm (14 in). The general shape is oval, tapering somewhat towards the tail. Like other flatfish, the body is flattened laterally and the fish lies on its side, with both eyes on the right side; the upper eye is slightly in front of the lower one. The dorsal fin starts from the edge of the head and has 79 to 83 soft rays. The anal fin has 57 to 67 soft rays and it and the dorsal fin are continuous with the caudal fin. The upper side of the fish is greyish-brown, with black blotches, arranged in indistinct longitudinal rows. The underside of the fish is whitish.[3][4]
Distribution
The Portuguese sole is native to the tropical and sub-tropical eastern Atlantic Ocean and the western end of the Mediterranean Sea. Its range extends from Portugal and Spain, through Algeria and Morocco, round the western coast of Africa as far south as the Republic of the Congo and Angola. It is also present in the Cape Verde Islands and São Tomé and Príncipe. It is a demersal fish, living on, or just above, the seabed at depths down to about 160 m (525 ft), on sandy and muddy substrates.[1]
Status
Over most of its range, the Portuguese sole is caught by trawling by artisanal fishermen, and in some areas, by commercial trawling as well. It is not usually the target species, but is caught largely as bycatch. There are no records of the quantities of fish taken, and the total population size of this fish is unknown, so the International Union for Conservation of Nature has rated its conservation status as "data deficient".[1]
