Piapara ( Almanca )

wikipedia DE tarafından sağlandı

Der Piapara (Leporinus obtusidens, Syn.: Curimatus obtusidens) gehört zu den Salmlerartigen und Strahlenflossern. Er ist in den Flüssen Brasiliens, Argentiniens, Paraguays und Uruguays weit verbreitet.[1]

Namen

Der Piapara wird in Brasilien auch Piava oder Piaú genannt. In Argentinien ist er unter dem Namen Boga oder Bogón geläufig.[1] Zu ihren Verwandten gehören der Aracu (Leporinus klausewitzi) im Amazonasbecken, die Piaús (Leporinus steindachneri Eigenmann, 1907) im Einzugsbereich der Flüsse Rio Araguaia, Rio Tocantins, Rio Paraná und São Francisco und die als Piavuçu und Piava bezeichneten lokalen Unterarten.[2]

Verbreitung

Sein Hauptverbreitungsgebiet erstreckt sich auf das Flussbecken des Rio Paraná, Río de la Plata, Río Uruguay und Rio São Francisco im östlichen Brasilien.

Morphologie

Leporinus obtusidens besitzt einen länglichen Körper und einen verhältnismäßig kleinen Kopf. Die kleinen nagetierartigen Zähne gaben der Gattung den Namen Leporinus, hasenartig. Die Juvenilform zeigt an den silberfarbenen Flanken häufig dunkle Flecken, die sich mit zunehmendem Alter verlieren. Sie werden zwischen 40 und 80 Zentimeter lang und im Rio de la Plata in Ausnahmefällen bis 8 Kilogramm schwer.

Lebensweise

Der Pipara lebt als Schwarmfisch im Süßwasser der subtropisch bis tropischen Klimazone benthopelagisch[3] und potamodrom.[1] Im Flusssystem des Rio de la Plata kommt die Art im ufernahen Bereich von Flüssen, Altarmen, Überschwemmungsauen, Seen, Einmündungen sehr häufig vor.[2] Leporinus obtusidens ernährt sich omnivor von Algen, Wasserpflanzen, kleinen Krustentieren, Wasserschnecken, Wasserinsekten und Pflanzensamen. In der Nähe von Flusshäfen gewöhnen sich die Fische auch an Getreidesaat, die beim Löschen der Frachtschiffe von Bord fällt. Zu ihren Feinden gehören Raubfische wie die Antennenwelse Pseudoplatystoma fasciatum und Pseudoplatystoma corruscans und teilweise für Jungfische auch der Barbensalmler Prochilodus lineatus. Die Geschlechtsreife erreicht er bei einer Länge von ca. 10 bis 20 Zentimetern und laicht in großer Zahl ab.[1] Als Wanderfisch auf dem Weg zu seinen Laichgründen überwindet der Piapara weite Distanzen. An einem Damm in Minas Gerais/Brasilien stellte man fest, dass die Schwimmblase der Fische durch das Betreiben hydroelektrischer Anlagen stark beschädigt und damit der Bestand der Tiere gefährdet wird.[4]

Nutzung

Der Piapara gehört zu den beliebten Speisefischen, der aufgrund seines schnellen Wachstums auch in Teichwirtschaften und Aquakulturen gehalten werden kann. Sein Sperma wird teilweise in Genbanken konserviert.[5][6] Außerdem ist der Piapara ein Sportfisch, der mit Naturködern wie grünem oder gequollenem Mais, Teig oder Schnecken gefangen wird.

Megaleporinus obtusidens ( İngilizce )

wikipedia EN tarafından sağlandı

Megaleporinus obtusidens is a South American species of headstander that inhabits the basins of the Paraná River and the Río de la Plata, the Uruguay River, and the São Francisco River (including minor rivers and tributaries like the Bermejo, Pilcomayo, Salí, Juramento, Dulce, and Uniguay). It may be found in the main courses and streams, as well as in lakes and lagoons; it often shelters among stones and aquatic vegetation.

In Argentina and Uruguay its common name is boga (sometimes augmentative bogón); in Brazil it is known as piapara. There is also a variant called piava and another called tres puntos ("three dots"). This species is also known by the technical synonym Curimatus obtusidens. The common name boga is applied to many other species of fish, usually unrelated to this one.

Megaleporinus obtusidens has an elongated wide body, with a comparatively small head and a blunt mouth; its teeth are reminiscent of the incisors of Lagomorpha, whence the name of the genus (leporinus, "hare-like", as in Leporidae). Its basic colour is a light greenish-gray, with three rounded dark spots in mid-flank, which may not be visible in some specimens. In young individuals there are also eight broad vertical streaks, joined in the back and coming down to the middle line. The back, as usual in this habitat, is darker than the belly.

The length and weight of the individuals are extremely variable according to the area, probably influenced by different feeding habits, opportunities and exploitation, as well as local sub-specific variants. In the Río de la Plata L. obtusidens is reported as weighing an average of 2 kg, with a maximum of 4 kg; in the upper course of the Paraná River it is about 4.5 kg; and in the middle course of the Paraná there are specimens of boga over 6 kg (with exceptionally developed ones over 8 kg). Adult individuals are reported between 40 and 80 cm long. The larger fish probably belong to other species of Leporinus (either L. friderici, which is still not very well known, or Megaleporinus macrocephalus, only recently classified as a separate species).

Megaleporinus obtusidens is an omnivore: it eats water plants, crabs and river snails. However, it prefers grain and seeds (wheat and maize), and it often gathers in large banks near ports, where cargo ships drop grains into the water. It is preyed upon by larger fish like the surubí and the dorado. It prefers warm waters and reproduces in spring and summer, starting at 2 years of age.

Megaleporinus obtusidens ( İspanyolca; Kastilyaca )

wikipedia ES tarafından sağlandı

La boga (Megaleporinus obtusidens)[2]​ es un pez teleósteo sudamericano, que abunda en cursos fluviales en toda la cuenca del río Paraná, río de la Plata, río Uruguay, río Paraguay, río São Francisco (y todos los demás integrantes de las cuencas y tributarios como el Bermejo, Pilcomayo, río Salí/Dulce, río Juramento/Salado); tanto en sus cursos mayores y arroyos como también en lagos y lagunas, protegiéndose entre piedras y vegetación acuática.

Sus proporciones corpóreas son extremadamente variables de acuerdo al área, seguramente influenciado por diferentes ofertas de alimentación, oportunidades y explotación, y a variantes locales subspecíficas. En el río de la Plata L. obtusidens pesa en promedio 2 kg, con máximos de 5 kg; en el curso superior del Paraná es de 4,5 kg; en su curso medio hay especímenes de boga sobre 7 kg (con excepcionales desarrollos de 9 kg). En las cooperativas de pescadores de Santa Fe (capital) y de Rosario (Argentina) es infrecuente encontrarse con formidables ejemplares de 10 kg. Los adultos alcanzan largos de 40 a 100 cm.
