Size 1170mm or 46.1" SL. Find near, nearer or same sized spp.
Identification Head compressed and elongate. Eyes reduced and located high on the head. Upper jaw surpasses lower. Barbels long, large and flattened. Coloration is gray above and lighter below with no spots on body. Specimens taken from white waters high in suspended sediment are bluish above and white-pink below. Caudal fin has long filaments on upper and lower lobes.
Sexing It has been reported that the average size of males captured by commercial fisheries is 65 cm and females 75 cm.
General Remarks This fish is only encountered in the deepest channels of rivers. The largest specimens reported from the Amazon are 100 cm while those from the Orinoco are reported to 117 cm. One of the most common species captured by commercial fisheries in the llanos of Colombia and Venezuela. Between May 1998 and May 1999 one ton was taken in Inirida and three tons in Puerto Carreno (Rio Orinoco). Over fishing has had a tremendous negative impact on this fish. In 1985 in the Rio Meta commercial fisheries reported 37.7 tons at an average length of 74 cm. By 1999 the catch had fallen to .8 tons with an average length of 59 cm. This represents a 98 percent decrease in 14 years! This fish is classified as ''Endangered'' and the capture of specimens smaller than 62 cm is illegal. This means that the small specimens imported for the aquarium trade are illegally acquired.
The common name is based on the thick barbels that make the fish look like it's dribbling.
