Centrocestus Formosanus
''Centrocestus formosanus'', the mystery fluke, is a trematode parasite of Asian origin that has found its way into North American streams and rivers. It not only affects the fountain darter, but also many species of commercially important fishes. It is also capable of infecting humans The parasite is transmitted by a freshwater snail red-rimmed melania ''Melanoides tuberculata'' Vergara D. & Velásquez L. E. (2009).

Trematode
Trematoda is a Class (biology), class of flatworms known as trematodes, and commonly as flukes. They are obligate parasite, obligate Endoparasites, internal parasites with a complex biological life cycle, life cycle requiring at least two Host (biology), hosts. The intermediate host, in which asexual reproduction occurs, is a Mollusca, mollusk, usually a snail. The definitive host, where the flukes Sexual reproduction, sexually reproduce, is a vertebrate. Infection by trematodes can cause disease in all five vertebrate classes: mammals, birds, amphibians, reptiles, and fish. Etymology Trematodes are commonly referred to as flukes. This term can be traced back to the Old English name for flounder, and refers to the flattened, rhomboidal shape of the organisms. The etymology of trematode stems from the Ancient Greek, Greek word ''trēmatṓdēs'', which means "pierced with holes", and refers to the worm's sucker (zoology), sucker, which pierces a hole in the host while the worm is ...

Parasite
Parasitism is a Symbiosis, close relationship between species, where one organism, the parasite, lives (at least some of the time) on or inside another organism, the Host (biology), host, causing it some harm, and is Adaptation, adapted structurally to this way of life. The entomologist E. O. Wilson characterised parasites' way of feeding as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as Armillaria mellea, honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the Orobanchaceae, broomrapes. There are six major parasitic Behavioral ecology#Evolutionarily stable strategy, strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), wikt:trophic, trophicallytransmitted parasitism (by being eaten), ...

Fountain Darter
The fountain darter (''Etheostoma fonticola'') is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the Family (biology), family Percidae, which also contains the perches, Gymnocephalus, ruffes, and Sander (fish), pikeperches. It is found in the headwaters of only two rivers in Texas, United States, the Comal River and the San Marcos River. It is generally smaller than long and feeds on small invertebrates. It is a federally listed endangered species of the United States and is also listed as endangered by the IUCN. Distribution and habitat The fountain darter is known from only two locations, primarily the headwaters of the spring-fed San Marcos River, having been observed as far as 1.25 miles downstream, as well as the upper reaches of the Comal River in central Texas. Its geographic isolation is reflective of its incredibly specific habitation preferences, which demand conditions that can only be found in these two Texas river headwat ...

Freshwater Snail
Freshwater snails are gastropod mollusks that live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a gastropod shell, shell, with very few exceptions. Some groups of snails that live in freshwater Respiratory system, respire using gills, whereas Pulmonata, other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung (e.g. ''Ampullariidae''). Most feed on algae, but many are detritivores and some are Filter feeding, filter feeders. Freshwater snails are indirectly among the deadliest animals to humans, as they carry parasitic worms that cause schistosomiasis, a disease estimated to kill between 10,000 and 200,000 people annually. There are thousands of known species, and at least 33–38 independent Lineage (evolut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-rimmed Melania
The red-rimmed melania (''Melanoides tuberculata''), also known as the Malayan livebearing snail or Malayan/Malaysian trumpet snail (often abbreviated to MTS by aquarists), is a species of freshwater snail with an operculum, a parthenogenetic, aquatic gastropod mollusk in the family Thiaridae. The common name comes from the presence of reddish spots on their otherwise greenish-brown shells. The species name is sometimes spelled ''M. tuberculatus'', but this is incorrect because '' Melanoides'' Olivier, 1804 was clearly intended to be feminine because it was combined with the feminine specific epithet ''fasciolata'' in the original description."Genus: ''Melanoides''" ''Molluscs of central Europe'', accessed 19 April 2011.

Black Carp
The black carp (''Mylopharyngodon piceus'') or Chinese black roach is a species of freshwater ray-finned fish belonging to the family Xenocyprididae, the East Asian minnows or sharpbellies. The black carp is the sole extant species of the genus '' Mylopharyngodon''. It is native to lakes and rivers in East Asia, ranging from the Amur Basin across China to Vietnam. One of the largest cyprinids in the world, the black carp has a typical length of , though it can reach up to in length and in weight. It is carnivorous and generally feeds on invertebrates such as snails, clams and mussels. Black carp, together with bighead carp, silver carp, and grass carp, make up the culturally important " four famous domestic fishes" used in polyculture in China for over a thousand years. It has also been introduced in the United States as one of the invasive " Asian carps", though it is not as widely distributed worldwide as the other three. In China, black carp is widely cultivated for foo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Farm
Fish farming or pisciculture involves commercial breeding of fish, most often for food, in fish tanks or artificial enclosures such as fish ponds. It is a particular type of aquaculture, which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans, molluscs and so on, in natural or pseudo-natural environments. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery. Worldwide, the most important fish species produced in fish farming are carp, catfish, salmon and tilapia. Global demand is increasing for dietary fish protein, which has resulted in widespread overfishing in wild fisheries, resulting in significant decrease in fish stocks and even complete depletion in some regions. Fish farming allows establishment of artificial fish colonies that are provided with sufficient feeding, protection from natural predators and competitive ...
