Monogenea
Monogeneans are a group of ectoparasitic flatworms commonly found on the skin, gills, or fins of fish. They have a direct lifecycle and do not require an intermediate host. Adults are hermaphrodites, meaning they have both male and female reproductive structures.L.A. Tubbsa et al. (2005). "Effects of temperature on fecundity in vitro, egg hatching and reproductive development of ''Benedenia seriolae'' and ''Zeuxapta seriolae'' (Monogenea) parasitic on yellowtail kingfish Seriola lalandi". ''International Journal for Parasitology''(35), 315–327. Some monogeneans are oviparous (egg-laying) and some are viviparous (live-bearing). Oviparous varieties release eggs into the water. Viviparous varieties release larvae, which immediately attach to another host. The genus ''Gyrodactylus'' is an example of a viviparous variety, while the genus ''Dactylogyrus'' is an example of an oviparous variety.

Cichlid
Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of ''Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Many cichlids, particularly tilapia, are important food fishes, while others, such as the ''Cichla'' species, are valued game fish. The family also includes many popular freshwater aquariu ...

Cichlidogyrus
''Cichlidogyrus'' is a genus of monopisthocotylean monogeneans in the family Ancyrocephalidae. The type-species of the genus is '' Cichlidogyrus arthracanthus'' Paperna, 1960, by original designation. All the species of the genus are parasites on the gills of fish, namely African Cichlidae, Nandidae and Cyprinodontidae. Species of ''Cichlidogyrus'' are parasitic in many clichlid species in the Lake Tanganyika; a recent study (2016) has shown that species which are parasite on deep-water fish show reduced parasite-host specificity in comparison to species from littoral waters, probably an adaptation to low host availability. According to Antoine Pariselle and Louis Euzet, 71 species of ''Cichlidogyrus'' were known in 2009 - new species have been described since. Nikol Kmentová, Milan Gelnar, Stephan Koblmüller and Maarten P.M. Vanhove estimated that the number of species was more than 100 in 2016 and Chahrazed Rahmouni, Maarten P. M. Vanhove and Andrea Šimková ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cichlidogyrus Evikae
''Cichlidogyrus evikae'' is a species of monopisthocotylean monogenean in the family Dactylogyridae (or Ancyrocephalidae according to certain classifications). It is a parasite of the gills of the fish '' Tanganicodus irsacae'' (Perciforme, Cichlidae) in Lake Tanganyika, Burundi. Etymology According to Rahmouni, Vanhove & Šimková, “the name ''evikae'' was given in honour of the Czech parasitologist Dr. Eva Řehulková (Department of Botany and Zoology, Faculty of Science, Masaryk University, Czech Republic The Czech Republic, or simply Czechia, is a landlocked country in Central Europe. Historically known as Bohemia, it is bordered by Austria to the south, Germany to the west, Poland to the northeast, and Slovakia to the southeast.

Pseudorhabdosynochus
''Pseudorhabdosynochus'' is a genus of monopisthocotylean monogeneans, included in the family Diplectanidae. The type-species of the genus is ''Pseudorhabdosynochus epinepheli'' ( Yamaguti, 1938). The genus includes more than 80 species, which are all parasitic on the gills of marine fish, especially groupers. Since groupers are mostly abundant in warm waters, species of ''Pseudorhabdosynochus'' are found in warm parts of the oceans, especially in coral reefs, but species have also been found in deep-sea groupers. Several species of ''Pseudorhabdosynochus'' are pathogens of maricultured groupers. Morphology All species of ''Pseudorhabdosynochus'' are small animals, ranging 0.3–1 mm in length. As most monogeneans, they are flat, with an anterior head bearing four oculi and head glands, a main elongate body and a posterior haptor. The digestive system includes an anterior muscular pharynx, and two lateral intestinal branches (or caeca); as in all Platyhelminthes, ther ...

Grouper
Groupers are fish of any of a number of genera in the subfamily Epinephelinae of the family Serranidae, in the order Perciformes. Not all serranids are called "groupers"; the family also includes the sea basses. The common name "grouper" is usually given to fish in one of two large genera: ''Epinephelus'' and ''Mycteroperca''. In addition, the species classified in the small genera ''Anyperidon'', ''Cromileptes'', ''Dermatolepis'', ''Graciela'', ''Saloptia'', and ''Triso'' are also called "groupers." Fish in the genus ''Plectropomus'' are referred to as "coral groupers." These genera are all classified in the subfamily Epiphelinae. However, some of the hamlets (genus ''Alphestes''), the hinds (genus ''Cephalopholis''), the lyretails (genus ''Variola''), and some other small genera (''Gonioplectrus'', ''Niphon'', ''Paranthias'') are also in this subfamily, and occasional species in other serranid genera have common names involving the word "grouper." Nonetheless, the word "grou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudorhabdosynochus Epinepheli
''Pseudorhabdosynochus epinepheli'' is a diplectanid monogenean parasitic on the gills of species of groupers. It is the type species of the genus '' Pseudorhabdosynochus'' Yamaguti, 1958. Description ''Pseudorhabdosynochus epinepheli'' is a small monogenean, about half a millimetre in length. Adults are hermaphroditic. The species has the general characteristics of other diplectanids, with a flat body and a posterior haptor, which is the organ by which the monogenean attaches itself to the gill of is host. The haptor bears two squamodiscs, one ventral and one dorsal, which are made up of numerous rows of rodlets. The reproductive organ include a single ovary and a single testis. The sclerotized male copulatory organ, or "quadriloculate organ", has the shape of a bean with four internal chambers, as in other species of '' Pseudorhabdosynochus''. The vagina also includes a sclerotized part, which is a complex structure. The sclerotised vagina comprises an anterior trumpet, fo ...

Calydiscoides Euzeti
''Calydiscoides euzeti'' is a species of monogenean of the family Diplectanidae. As all members of the family Diplectanidae, it has a single posterior testis and a single ovary that wraps the lateral caecum of the intestine. As all members of the genus Calydiscoides, it is characterized by the presence of lamellodiscs, which are specialized attachment organs made up of concentric lamellae, on the posterior part of its body. The species is distinguished from other species of the genus ''Calydiscoides'' by the shape and size of its male copulatory organ, which is elongate in shape with an anterior curved whip, and 70–83 μm in length. It is ectoparasite on the gills of two species of marine fish, emperors An emperor (from la, imperator, via fro, empereor) is a monarch, and usually the sovereign ruler of an empire or another type of imperial realm.

Atlantic Salmon
The Atlantic salmon (''Salmo salar'') is a species of ray-finned fish in the family Salmonidae. It is the third largest of the Salmonidae, behind Siberian taimen and Pacific Chinook salmon, growing up to a meter in length. Atlantic salmon are found in the northern Atlantic Ocean and in rivers that flow into it. Most populations are anadromous, hatching in streams and rivers but moving out to sea as they grow where they mature, after which the adults seasonally move upstream again to spawn. When the mature fish re-enter rivers to spawn, they change in colour and appearance. Some populations of this fish only migrate to large lakes, and are "landlocked", spending their entire lives in freshwater. Such populations are found throughout the range of the species. Unlike Pacific species of salmon, ''S. salar'' is iteroparous, which means it can survive spawning and return to sea to repeat the process again in another year. Such individuals can grow to extremely large sizes, althoug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
