The fivebeard rockling (Ciliata mustela) is a coastal ray-finned fish of the family Lotidae. the lings and rocklings. It is found in the eastern Atlantic Ocean. It is not a fish of any commercial importance.
The fivebeard rocklings is a long, slender fish which may attain a length of 25 centimetres (9.8 in). It has a smooth, scaleless body with unusual and long dorsal, which is made up of a first ray followed by a line of vibrating rays in a furrow in the back. The front part of the dorsal fin does not have any membrane connecting the rays although the rear dorsal fin is which runs the length of the body, as does the anal fin, is made up of rays connected by membrane. [3] It has five barbels around its mouth, two above either nostril and a single barbel on the lower jaw. It has a rather small mouth with the corners of the mouth just going beyond the eye. The main colour is dark brown. [4] This fades to pale gray-brown on the underside. [2]
The fivebeard rockling is found in the eastern Atlantic from Finnmark to Lisbon, including the Skagerrak, the Kattegat, Iceland and around Great Britain and Ireland. [2]
The fivebeard rockling is found in the intertidal zone, often under rocks. They are usually found in rocky areas but it can be found in breakwater pools on sandy shores so long as these have a growth of algae. [4] These fish can display homing behaviour and are normally found no deeper than the lower limit for the growth of green algae, around 20 metres (66 ft). They are predatory fish and the major part of their diet is crustaceans but they will eat polychaetes, gastropods and small fish, they have also been recorded consuming algae. The five-bearded rockling has a temperature range of 8 to 24 °C (46 to 75 °F) Both sexes reach maturity at around one year old. A smaller female may lay as few as 9,000 eggs when spawning, while the largest females may lay as many as 30,000. Spawning takes place in the deeper waters of the Atlantic to the west of Ireland during February to May. The eggs and larvae are pelagic. [1]
The fivebeard rockling is regarded as being of least concern by the IUCN and is not a commercially important species, in the warmer waters in which it occurs it may be threatened by climate change. [1]
The black sea bass is a species of marine ray-finned fish, a sea bass from the subfamily Serraninae which is part of the family Serranidae, which also includes the groupers and anthias. It is found in the western Atlantic Ocean, where it is an important species for commercial and recreational fisheries.
The roach, or rutilus roach, also known as the common roach, is a fresh- and brackish-water fish of the family Cyprinidae, native to most of Europe and western Asia. Fish called roach can be any species of the genera Rutilus and Hesperoleucus, depending on locality. The plural of the term is also roach.
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 pyjama shark or striped catshark is a species of catshark, and part of the family Scyliorhinidae, endemic to the coastal waters of South Africa. This abundant, bottom-dwelling species can be found from the intertidal zone to a depth of around 100 m (330 ft), particularly over rocky reefs and kelp beds. With a series of thick, parallel, dark stripes running along its stout body, the pyjama shark has an unmistakable appearance. It is additionally characterized by a short head and snout with a pair of slender barbels that do not reach the mouth, and two dorsal fins that are placed far back on the body. It can grow up to a length of 1.1 m (3.6 ft) long.
Holacanthus bermudensis, also known as the blue angelfish or Bermuda blue angelfish, is a species of ray-finned fish, a marine angelfish belonging to the family Pomacanthidae. It occurs in the western Atlantic Ocean.
The grey triggerfish, or gray triggerfish, is a species of ray-finned fish in the triggerfish family. The species is native to shallow parts of the western Atlantic from Nova Scotia to Argentina and also the eastern Atlantic, the Mediterranean Sea and off Angola on the west coast of Africa.
The snowy grouper is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found in the western Atlantic Ocean.
Synodontis granulosus is a species of upside-down catfish endemic to the Democratic Republic of the Congo, Burundi, Zambia, and Tanzania, where it is only known from Lake Tanganyika. It was first described by Belgian-British zoologist George Albert Boulenger in 1900, from specimens collected at multiple points along the shore of Lake Tanganyika. The species name comes from the Latin word "granulum", meaning of grain, and refers to the granular papillae present on the skin of the fish's body.
The Lake Victoria squeaker is a species of upside-down catfish that is native to Kenya, Burundi, Tanzania and Uganda where it is found in Lakes Kioga and Victoria and the Victorian Nile in the lower Kagera River and the Malagarasi River drainage. It was first described by British-Belgian zoologist George Albert Boulenger in 1906, from specimens collected in the Lake Victoria at Buganga, Uganda and Entebbe, Uganda by Mr. E. Degen. The species name victoriae is derived from the location where the species was originally discovered, Lake Victoria.
The shore rockling is a mottled brown, small, elongated fish. This eel-like fish has three barbels on its head, with the second dorsal fin and the anal fin running the length of most of its body. These fins may be viewed moving in a continuous wave motion.
Synodontis clarias, known as the red tailed synodontis, or the mandi, is a species of upside-down catfish that occurs widely in the waters of northern Africa. It was first described by Swedish zoologist Carl Linnaeus in 1758 as Silurus clarias. The original specimens were obtained in Egypt, near Cairo. The meaning of the species name clarias is not certain, but may possibly have been used to mean "bright" or "clear".
Synodontis macrostigma, known as the largespot squeaker, is a species of upside-down catfish that is native to Angola, Botswana, Namibia, South Africa and Zambia where it is found in the Cunene, Okavango, upper Zambezi and Kafue River systems. It was first described by British-Belgian zoologist George Albert Boulenger in 1911, from specimens collected in the Okovango River, Botswana, by R. B. Woosnam. The species name macrostigma is derived from the Greek word makros, meaning "large", and the Greek word stigma, meaning "mark" or "spot" and refers to the large spots on the sides of the fish.
Synodontis marmoratus is a species of upside-down catfish that is native to Cameroon where it is found in the Sanage and Nyong Rivers. It was first described by Swedish zoologist and conservationist Einar Lönnberg in 1895, from a specimen collected from Bonge, Cameroon.
Synodontis multimaculatus, known as the dotted synodontis, is a species of upside-down catfish that is native to the Democratic Republic of the Congo where it is found in the Ubangi River. It was first described by British-Belgian zoologist George Albert Boulenger in 1902, from a specimen collected in the Ubangi River in Mobayi-Mbongo, the Democratic Republic of the Congo. The species name multimaculatus is derived from the word multi, meaning many, and the Latin word maculatus, meaning spots, referring to the many spots on the fish.
Synodontis omias is a species of upside-down catfish native to the Niger River basin of Guinea, Mali, Niger and Nigeria. It was first described by German-born British zoologist, ichthyologist, and herpetologist Albert Günther in 1864, from a specimen collected in Jebba, Nigeria, on the Niger River. There have been very few specimens of this species identified, and it may be the same species as S. budgetti from the Upper Niger.
