Pacú
Pacu () is a common name used to refer to several species of omnivorous South American freshwater Serrasalmidae, serrasalmid fish related to piranhas. Pacu and piranha do not have similar teeth, the main difference being jaw alignment; piranha have pointed, razor-sharp teeth in a pronounced underbite, whereas pacu have squarer, straighter teeth and a less severe underbite, or a slight malocclusion, overbite. Pacu, unlike piranha, mainly feed on plant material and not flesh or Fish scale, scales. Additionally, the pacu can reach much larger sizes than piranha, at up to in total length and in weight. Name The common name ''pacu'' is generally applied to fish classified under the below listed Genus, genera. Among these, several genera contain species where commonly used English names include the word ''pacu'', as listed. *Subfamily Colossomatinae **''Colossoma'' – black pacu, black-finned pacu, giant pacu **''Mylossoma '' **''Piaractus'' – red-bellied pacu, small-scaled pacu ...

Shedd Aquarium
Shedd Aquarium (formally the John G. Shedd Aquarium) is an indoor public aquarium in Chicago. Opened on May 30, 1930, the aquarium holds about 32,000 animals. It is the third largest aquarium in the Western Hemisphere (after the Georgia Aquarium and The Seas at Epcot) and the 11th-largest aquarium in the world. The Shedd Aquarium is a highly-ranked world aquarium and at one time was the largest indoor facility in the world. It is the first inland aquarium with a permanent saltwater fish collection.

Fish Scale
A fish scale is a small rigid plate that grows out of the skin of a fish. The skin of most jawed fishes is covered with these protective scales, which can also provide effective camouflage through the use of reflection and colouration, as well as possible hydrodynamic advantages. The term ''scale'' derives from the Old French , meaning a shell pod or husk. Scales vary enormously in size, shape, structure, and extent, ranging from strong and rigid armour plates in fishes such as shrimpfishes and boxfishes, to microscopic or absent in fishes such as eels and anglerfishes. The morphology (biology), morphology of a scale can be used to identify the species of fish it came from. Scales originated within the jawless ostracoderms, ancestors to all jawed fishes today. Most bony fishes are covered with the cycloid scales of salmon and carp, or the ctenoid scales of perch, or the ganoid scales of sturgeons and gars. Cartilaginous fishes (sharks and rays) are covered with placoi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paraguay River
The Paraguay River (''Ysyry Paraguái'' in Guarani language, Guarani, ''Rio Paraguai'' in Portuguese language, Portuguese, ''Río Paraguay'' in Spanish language, Spanish) is a major river in south-central South America, running through Brazil, Bolivia, Paraguay and Argentina.

Course The Paraguay's source is south of Diamantino in the Mato Grosso state of Brazil. It follows a generally southwesterly course, passing through the Brazilian city of Cáceres, Mato Grosso, Cáceres. It then turns in a generally southward direction, flowing through the Pantanal wetlands, the city of Corumbá, then running close to the Brazil-Bolivia border for a short distance in the Brazilian states of Mato Grosso and Mato Grosso do Sul.

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 ...

''Piaractus brachypomus'' also known as the red-bellied Pacu or pirapitinga, is a large species of pacu, a close relative of piranhas and silver dollar (fish), silver dollars, in the serrasalmid family.Nico, L.; P. Fuller; and M. Neilson (22 October 2013)Piaractus brachypomus.USGS Nonindigenous Aquatic Species Database, Gainesville, FL. Retrieved 2 March 2017.

Colossoma Macropomum
The tambaqui (''Colossoma macropomum'') is a large species of freshwater fish in the family Serrasalmidae. It is native to tropical South America, but kept in aquaculture and introduced elsewhere. It is also known by the names black pacu, black-finned pacu, giant pacu, cachama, gamitana, and sometimes as pacu (a name used for several other related species). The tambaqui is currently the only member of ''Colossoma'', but the '' Piaractus'' species were also included in this genus in the past. Distribution The tambaqui is native to freshwater habitats in the Amazon and Orinoco basins of tropical South America. In nutrient-rich whitewater rivers such as the Madeira, Juruá, Putumayo (Içá) and Purus it ranges throughout, all the way up to their headwaters.Araujo-Lima, C.A.R.M.; and M.L. Ruffino (2003).

Serrasalminae
The Serrasalmidae (serrasalmids) are a family of characiform fishes native to freshwater habitats of South America. They include more than 90 species. The name means "serrated salmon family", which refers to the serrated keel running along the belly of these fish. Fish classified as Serrasalmidae are also known by these common names: pacu, piranha, and silver dollar. These common names generally designate differing dental characteristics and feeding habits. Description Serrasalmids are medium- to large-sized characiform bony fishes that reach about long, generally characterized by a deep, laterally compressed body with a series of midventral abdominal spines or scutes, and a long dorsal fin (over 16 rays). Most species also possess an anteriorly directed spine just before the dorsal fin extending from a supraneural bone; exceptions include members of the genera '' Colossoma'', '' Piaractus'', and '' Mylossoma''. Most serrasalmids have about 60 chromosomes, ranging from 54 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myleus
''Myleus'' is a genus of serrasalmids from South America, where found in the Amazon, Orinoco and São Francisco basins, as well as the river basin of the Guiana Shield.Ota, R.P., Röpke, C.P., Zuanon, J. & Jégu, M.

Volume II, ''Santo Antonio Energia, São Paulo, 12–47.'' They are found in rivers with moderately or fast-flowing water, including rapids. They are primarily herbivores, but also take some animal matter. Depending on the exact species, they reach up to in standard length, and the adult males have a double-lobed anal fin and filamentous extensions on the dorsal fin. Their strong teeth means that larger individuals can inflict severe bites on humans. Species There are currently 6 recognized species of ''Myleus''. Several others have been moved to the genus ''Myloplus''. * '' Myleus altipinnis'' (Valenciennes, 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
