Distribution

These catfish originate from the Mekong basin, and are reported from Chao Phraya, Mae Klong, and peninsular Thailand river systems. [1] There is also an introduced population in Malaysia. [2]

Appearance and anatomy

Hemibagrus wyckioides reaches a length of 130 centimetres (51 inches) TL. [1] This species is the largest Bagrid catfish in Asia, and may reach 80 kilograms. [3] The caudal fin is white when the fish is small, but it becomes bright red when it reaches about 15 cm (6 in). [1]

Hemibagrus wyckii bears a resemblance to H. wyckioides, however, H. wyckioides lacks serrations on the dorsal fin spine, has a shorter dorsal fin base, and shorter maxillary barbels. [3]

Ecology

Hemibagrus wyckioides occurs in large upland rivers, and is common in areas with rocky bottoms and irregular depths. [1] [3] These fish do not migrate, but they reproduce locally and enter the flooded forest during high water in JulyOctober. [3] H. wyckiodies feed on insects, prawns, fish, and crabs. [3]

Relationship to humans

This fish is marketed fresh as a food fish. [1] Hemibagrus are aquacultured in Asian countries. [4]

Hemibagrus wyckioides and Hemibagrus wyckii are the two members of this genus imported as aquarium fish. [4] This species will rearrange decorations in the aquarium. [5] These fish are not picky, and will eat a variety of fish foods. [5] This species is sometimes claimed to be the most aggressive freshwater fish in the world, and should be left alone. [6]

As an Invasive Species

H. wyckioides is an invasive species in Malaysia. They were introduced as a food fish and some individuals escaped from fish farms or were released illegally into rivers. It is now illegal to keep H. wyckioides in net cages in Malaysia. [2]
