Brachyplatystoma vaillantii in Trinidad and Tobago
Laulao catfish

Go to Species Summary

Brachyplatystoma vaillantii   (Valenciennes, 1840)
Family:	Pimelodidae (Long-whiskered catfishes)			picture (Brvai_u0.jpg) by IBAMA
Order:	Siluriformes  (catfish)
Class:	Actinopterygii (ray-finned fishes)
FishBase name:	Laulao catfish
Max. size:	150 cm TL (male/unsexed; Ref. 5217); max. published weight: 20.0 kg (Ref. 5273)
Environment:	demersal; potamodromous
Climate:	tropical
Global Importance:	fisheries: commercial
Resilience:	Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.)
Distribution:	South America: Amazon and Orinoco River basins and major rivers of the Guianas and northeastern Brazil.
Biology:	Juveniles and subadults frequently found at river mouths and estuaries. Occurs downstream from the first falls where the water is charged with mud and the bottom is muddy. In the Amazon, it can sometimes be caught in the upper part up to the foot of the Andean range where it appears to be more rare than Brachyplatystoma filamentosum and Brachyplatystoma flavicus but never in the zones prone to flood. Reproductive migrations probably occur like in other Brachyplatystoma (Ref. 35381). Usually caught with longlines and drift nets (Ref. 35381). Its flesh of excellent quality is highly appreciated
Threatened:	Not Evaluated, see IUCN Red List  , (Ref. 36508)
Dangerous:	harmless
