Dagetichthys lusitanicus, 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]
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]
The Portuguese sole is native to the tropical and sub-tropical eastern Atlantic Ocean. Its range extends from Portugal to Angola. It is also present in the Cape Verde Islands and São Tomé and Príncipe. It was first recorded in the Mediterranean Sea in the early 1960s along the coast of Spain and has since extended its range to Libyan waters. [5]
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]
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".

The European sprat, also known as brisling, brisling sardine, bristling, garvie, garvock, Russian sardine, russlet, skipper or whitebait, is a species of small marine fish in the herring family Clupeidae. Found in European, West Asian and North African waters, it has silver grey scales and white-grey flesh. Specific seas in which the species occurs include the Irish Sea, Black Sea, Baltic Sea and Sea of the Hebrides. The fish is the subject of fisheries, particularly in Scandinavia, and is made into fish meal, as well as being used for human consumption. When used for food it can be canned, salted, breaded, fried, boiled, grilled, baked, deep fried, marinated, broiled, and smoked.
The common ling, also known as the white ling or simply the ling, is a large member of the family Lotidae, a group of cod-like fishes. It resembles the related rocklings, but it is much larger and has a single barbel. This species is unrelated to the pink ling, Genypterus blacodes, from the Southern Hemisphere. The common ling is found in the northern Atlantic, mainly off Europe, and into the Mediterranean Basin. It is an important quarry species for fisheries, especially in the northeastern Atlantic, although some doubts exist as to the sustainability of the fisheries. As an edible species, it is eaten fresh, frozen, or dried, but also preserved in lye, while the roe is a delicacy in Spain.
The bignose shark is a species of requiem shark, in the family Carcharhinidae. Distributed worldwide in tropical and subtropical waters, this migratory shark frequents deep waters around the edges of the continental shelf. It is typically found at depths of 90–430 m (300–1,410 ft), though at night it may move towards the surface or into shallower water. The bignose shark is plain-colored and grows to at least 2.7–2.8 m (8.9–9.2 ft) in length. It has a long, broad snout with prominent nasal skin flaps, and tall, triangular upper teeth. Its pectoral fins are long and almost straight, and there is a ridge on its back between the two dorsal fins.
The false catshark or sofa shark is a species of ground shark in the family Pseudotriakidae, and the sole member of its genus. It has a worldwide distribution, and has most commonly been recorded close to the bottom over continental and insular slopes, at depths of 500–1,400 m (1,600–4,600 ft). Reaching 3.0 m (9.8 ft) in length, this heavy-bodied shark can be readily identified by its elongated, keel-like first dorsal fin. It has long, narrow eyes and a large mouth filled with numerous tiny teeth. It is usually dark brown in color, though a few are light gray.
Squatina squatina, the angelshark or monkfish, is a species of shark in the family Squatinidae, that were once widespread in the coastal waters of the northeastern Atlantic Ocean. Well-adapted for camouflaging itself on the sea floor, the angelshark has a flattened form with enlarged pectoral and pelvic fins, giving it a superficial resemblance to a ray. This species can be identified by its broad and stout body, conical barbels, thornless back, and grayish or brownish dorsal coloration with a pattern of numerous small light and dark markings. It measures up to 2.4 m (7.9 ft) long.
The witch, known in English by a variety of other common names including the witch flounder, pole flounder, craig fluke, Torbay sole, and grey sole, is a species of flatfish from the family Pleuronectidae. It occurs on both sides of the North Atlantic Ocean on muddy sea beds in quite deep water. In northern Europe it has some importance in fisheries as a food fish.
Mullus barbatus is a species of goatfish found in the Mediterranean Sea, Sea of Marmara, the Black Sea and the eastern North Atlantic Ocean, where its range extends from Scandinavia to Senegal. They are fished, mostly by trawling, with the flesh being well regarded. The International Union for Conservation of Nature has assessed their conservation status as being of "least concern".
The solenette or yellow sole, Buglossidium luteum, is a species of flatfish in the family Soleidae, and the only member of its genus. It is characterized by its small size, low-slung semi-circular mouth, and regularly placed dark fin rays. A common and widespread species, it is native to sandy bottoms in the northeastern Atlantic Ocean and the Mediterranean Sea. It is of little commercial value.
Cephalopholis taeniops, the African hind, bluespotted sea bass or spotted grouper, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is in the family Serranidae which also includes the anthias and sea basses. This species occasionally makes its way into the aquarium trade and is a target for local fisheries. It is found in the eastern Atlantic Ocean.
The Mediterranean scaldfish, also known as the scaldfish, is a species of benthic left eyed flatfish belonging to the family Bothidae. It is found in the eastern Atlantic of Europe and Africa as well as the Mediterranean, and is of minor interest to fisheries.
The common guitarfish is a species of cartilaginous fish in the family Rhinobatidae. It is native to the eastern Atlantic Ocean and the Mediterranean Sea. It is a bottom-dwelling fish feeding on crustaceans, other invertebrates and fish. The females give birth to live young. Its lifestyle makes it vulnerable to trawling and other fishing methods, populations seem to be declining and it has disappeared from parts of its range.
The dog snapper, also known as the dogtooth snapper, pargue or snuggletooth snapper, is a species of marine ray-finned fish, a snapper belonging to the family Lutjanidae. It is native to the Atlantic Ocean. It is a commercially important species, and is popular for display in public aquaria.
Dagetichthys lakdoensis is a species of freshwater sole native to the Bénoué basin in Cameroon, with recent records from Nigeria in the Niger Delta. This species grows to a length of 40 centimetres (16 in) TL. This species is one of three known members of its genus, the others being the marine Dagetichthys lusitanicus and Dagetichthys marginatus
The Egyptian sole is a species of flatfish in the true sole family, Soleidae. It lives on the sandy or muddy seabed of the Mediterranean Sea, and is now colonising the Red Sea. It often semi-immerses itself in the substrate. The upper side is greyish-brown while the underside is white. It grows to a maximum length of about 70 cm (28 in). This fish is used for human consumption and is prized as a food fish. It is caught mostly by trawling on the seabed.
Upeneus moluccensis, the goldband goatfish, golden-banded goatfish or Moluccan goatfish, is a species of Indo-Pacific goatfish from the red mullet and goatfish family, the Mullidae. It is widespread in the warmer waters of the Indian and Pacific Oceans as far east as New Caledonia and has colonised the eastern Mediterranean Sea from the Red Sea via the Suez Canal, making it a Lessepsian migrant.
