Yamú can be found in Meta, Casanare, Arauca, Dorada and Norte de Santander. It is a native species of the Orinoco basin.
It is a native fish of the Colombian Orinoquia. Since 1984 it loomed like a fish with potential for cultivation in ponds, but only until 1992 the first breeding tests were held in captivity.
They are nervous fish, carnivorous with omnivores tendency, especially in the early days of larva and fingerling, are extremely voracious but accept the commercial concentrate for fish very well. The breeding season goes from February to June, depending on the time of the beginning of rains.
The Yamú can be fished mainly by launching and by depth. During the summer the yamú can be induced to bite with artificial lures mostly undulated metal spoons. Also attacks the small "tacos", "flats", rapalas and vibrating spoons. Dragging is rarely used because of the reduced flow of the waters where it lives, but where this method can be used, performance is very good. In some places, it is ideal to ascend the river and to come down with the engine off, throwing to the banks.
