Now found in Thailand, Asia,
where this large South American Pim has now been introduced
to large ponds and fishing lakes for sport fishing
along with other similar sized members of the Pimelodidae
family such as Pseudoplatystoma
fasciatum,Sorubimichthys
planiceps and
the Red Tail CatfishPhractocephalus
hemiolopterus.There
has been 5 new species described by Buitrago-Suárez,
U.A. and B.M. Burr in 2007, to go alongside P.
tigrinum, P. fasciatum
and P. corruscans. These species are
P. punctifer (Castelnau), P.
reticulatum Eigenmann
& Eigenmann, P. orinocoensen, P.
metaense, and
P.
magdaleniatum.
So far P. punctifer is the only species
that has not been accepted in some publications in
print and on the internet.Two species (P.
punctifer ? and P. tigrinum) are sympatric
in the Amazon Basin, two (P. metaense and
P. orinocoense) are sympatric in the Orinoco
Basin, and two others, P. corruscans and
P. reticulatum, are sympatric in the Paraná.
Pseudoplatystoma magdaleniatum and P.
fasciatum each occur as the only species of Pseudoplatystoma
in their respective individual ranges. Aquarium
Care: Its tank should have a shaded area
at the back such as a large branch and plants to hide
under as it is nocturnal, and also the lighting should
not be too bright. Should not be kept with any fish
that is smaller than itself and it also should be
housed in a very large tank. The best companions would
probably be large Pacu's or similar sized fish that
would not be swallowed. In my opinion this wonderful
looking Pim should only be kept in Public Aquariums as
it can damage its large nose if kept in too confined
an area, it can get jumpy too if feels its barbels
on the tank sides as it turns around. It can also
go of its food as well, if it is anyway disturbed.
Diet: In their natural habitat they
eat other fish such as characins and other catfish,
they also eat freshwater crabs. In the aquarium a
diet of earthworms, freshwater fish such as trout
and also shrimp and prawns. You should only feed when
it starts looking actively for it, as they will rest
for a few days after feeding to digest their food.
Etymology: The specific name corruscans:
Apparent misspelling of coruscans (L.), flaming or
flashing or glittering, probably referring to bright
colouration, yellow-orange above and silver below.
South America:
Sao Francisco and Paraná River basins. Type
locality: In flumine S. Francisci, Brazil.
Size:
150.0cm. (5ft 4ins)
Temp:
22-26°C (71-77°F)
p.H.
6.0-7.0.
IUCN
Red List
Pseudoplatystoma
corruscans can be found in the San Francisco and
La Plata river basins in South America. Decreased commercial
fishing landings have been recorded at some points in
the São Francisco and Paraná basins, which
suggests a decline in the subpopulations in at least
these two basins. The reduction in population size is
directly linked to two main factors: the construction
of hydroelectric plants and overfishing, while there
may be additional impacts of hybridisation with congeners
and pollution. It is expected that there will be contributions
from individuals from the subpopulations of Argentina
and Paraguay to the Pantanal, where the subpopulations
are still in the best state of conservation. However,
contributions are not expected for the subpopulations
occurring in the upper Paraná and São
Francisco, which are more affected by the fragmentation
caused by successive dams. Based on the reductions in
fishing landings attested to various areas, a population
decline of 25% in the last 45 years (three generations)
is suspected. Thus, Pseudoplatystoma corruscans
is categorised as Near
Threatened (NT), because it approaches
VU A2bcde, (IUCN 2023).
