The walking catfish is a freshwater fish that can crawl across wet land to reach new water. It lives in Southeast Asia and has also been introduced to places such as Florida. Its spiny defence is the reason it needs careful handling.1

Hoe om dit te herken

Elongated body, grey or grey-brown in colour1
Often covered on its sides with small white spots1
Long dorsal and anal fins, and several pairs of sensory barbels1
Scaleless skin covered in mucus1
No adipose fin, a small fleshy fin on the back near the tail1

Word dikwels verwar met: It is often confused with North American ictalurid catfish and with close relatives such as C. magur. The walking catfish can be told apart from the North American ictalurid catfish because it lacks an adipose fin.1

Gifkrag

Giftige stekels

Skerp stekels dra die gif. Dit maak seer as jy daarop trap of dit gryp.

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

It must be handled carefully when fished because of its embedded sting or thorn-like spines. It is also harmful as an invasive species, because it eats the food of native fish, preys on their young and can destroy fish farms.1

Wat doen dit as dit bang is?

It has a sting or thorn-like spine hidden behind its fins, which it uses to defend itself.1

As sy stekels jou steek

Sit die wond in warm water, so warm as wat die persoon kan verdra sonder om te brand (toets dit met jou eie hand), vir 30 tot 90 minute. Kry mediese hulp, veral vir klipvisse en pylsterte.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As sy stekels jou steek: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

It can survive 18 hours out of water.1

It moves over land with snake-like wiggles, using its pectoral fins to stay upright.1

In Florida, fish farmers have had to put up fences to protect their ponds from them.1

It often rises to the surface to gulp air, because it breathes air as well as using water.1

Walking catfish were imported to Florida in the early 1960s for aquaculture, and escapes led to wild populations.1

In Indonesia it is known as lele and is the main ingredient in dishes such as pecel lele.1

Mite-breker

Mite: The walking catfish truly walks on land like a four-legged or two-legged animal.

Waarheid: It does not walk in that way. It uses its pectoral fins to stay upright while it wiggles its body in snake-like movements.1
