The black armored catfish Rhinelepsis
aspera Agassiz, 1829 (‘cascudo-preto’)
is an important and currently rare commercial fish
of the São Francisco River, although still
found in large numbers in its main tributary, the
Paracatu River. Its flesh is firm, tasty and practically
devoid of bones and fat. It is caught with gill nets.
Habitat: Among the Loricariidae of
the São Francisco river basin, R. aspera
is the one that reaches the largest size, and can
exceed 4 kg of body weight. R. aspera can
be found throughout the basin of the São Francisco
and Paraná rivers, with its typical location
in the São Francisco river (Fowler, 1954).
Description: The Rhinelepis
group is unique among Loricariids for possessing a
round (normal) iris versus a bilobed iris (although
it is often hard to see the flap in bilobed, preserved
fishes). The species has also thick plates and lacks
an adipose fin. Reproduction: May
not be possible as this genera migrate to spawn, and
scatter their eggs with no parental protection. Aquarium
Care: Grows rather large and would need a
large tank to accommodate it. Diet:
Omnivore: Feed veg, frozen foods and also tablet and
