Siamese catfish

Location at the Zoo: Indomalaya



Region:

Southeast Asia

Class:

Osteichthyes

Order:

Siluriformes

Family:

Pangasiidae

Genus:

Pangasius

Scientific Name:

Pangasius sutchi

Description

: Length up to 100 cm or more. The elongated dark grey body resembles that of a shark. It has large eyes, a small mouth and the tail is deeply forked. The back is darker than the main body colour. A slender, horizontal, white stripe extends from the base of the tail to the gill cover. The fins are light grey to transparent. Males are more slender and have darker striping than the females.

Distribution

: Southeast Asia, particularly Mekong and Maeklong basins, but has been introduced elsewhere.

Habitat

: Tropical freshwater: found in large schools, swimming in rapid areas of large rivers.

Food

: Omnivorous, feeding on smaller fishes and crustaceans as well as vegetable debris.

Reproduction and Development

: It moves upstream to spawn during the flood season while the waters are high and returns downstream to seek rearing habitats when the water levels recede. The dates of the migrations vary depending on the river system. In the Mekong river basin, they migrate upstream in May to July and return downstream during September through December. South of the Khone Falls, upstream migration occurs in October to February, with its peak in November to December. The habitat consists of rapids and sandbanks, interspersed with deep rocky channels and pools. Spawning takes place during the monsoon season. Large numbers of eggs are laid. Egg production increases dramatically with the size of the fish. Larvae and fry drift downstream with the current.

Adaptations

: It can survive under varied water conditions. It consumes anything edible. It is migratory moving with flood waters, utilizing floodplains.

Threats to Survival

: In its original habitat, the Mekong Delta, it was extensively fished. It is an important aquaculture food fish and has been introduced and farmed throughout Southeast Asia. Siamese catfish that escape from aquaculture facilities may compete with wild fish and have habitat and environmental impacts, especially in areas where Siamese catfish are not yet established.

Status

: IUCN: Not listed; CITES: Not Listed

Zoo Diet

: Fruit gelatine, fish gelatine
