The flooded fields of Maranhão form an
immense floodplain, variable according to the rainfall
regime in the region, whose characteristics are
conducive to the feeding, reproduction and growth of
various species, with considerable commercial interest
and with morphophysiological aspects that suggest a
adaptability for feedlot fish production. Thus, this study
aimed to elucidate the main species of siluriformes in the
flooded fields of the plains of Maranhão with
zootechnical potential. Through literary review, three
catfish species of the order Siluriformes, Pimelodus
blochii, Hemisorubim platyrhynchos and
Trachelyopterus galeatus, whose size reached 25, 50 and
18 cm, respectively, were identified.
