The channel catfish is a freshwater fish native to North America, and it is the continent's most common catfish. It lives in rivers, lakes, ponds and reservoirs, and it is a popular fish for anglers to catch and eat. It has spines on some of its fins that can cause a small injury if it is handled badly.1

Noord-Amerika

Tuis

It thrives in rivers, reservoirs, lakes and ponds, and it lives in murky water. Adults are often caught by anglers, and the species is also farmed (aquaculture) in the United States. Females lay eggs in crevices, hollows or debris to shelter them from fast currents.1

Wat eet dit?

Adults over 45 cm mainly prey on fish such as yellow perch and sunfish, and also eat snails, clams, crayfish, frogs, insects and plants. Young channel catfish eat a wide mix of plants and animals. They feed by opening the mouth quickly to pull in water and prey, then swallow prey whole.1

Hoe om dit te herken

Four pairs of barbels (whisker-like feelers) surround the mouth.1
Sharp spines sit on the pectoral (side) fins and the dorsal (back) fin.1
The pectoral spine has serrations (small saw-like ridges).1
It lives in muddy or dark water and finds food mainly by smell and taste.1

Gifkrag

Giftige stekels

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

Wat doen sy gif as dit byt of steek?

The pectoral spine has poisonous tissues that help deter predators.1

Hoe gevaarlik is dit vir mense?

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

Its fin spines may cause injury if the fish is handled improperly. A prick from a spine is no more dangerous than a mosquito sting.1

Wat doen dit as dit bang is?

It can lock its pectoral spine as a defence, and the serrated, poison-bearing spine helps to deter predators.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

Taste buds cover the whole body, and they are most dense on the four pairs of barbels around the mouth.1

They can sense certain amino acids in water at about one part per 100 million, which helps them find food in murky water.1

The largest channel catfish on record weighed 26 kg and was caught in South Carolina in 1964.1

Channel catfish are the most fished catfish in the United States, with around 8 million anglers catching them each year.1

Fossils of this species have been found in central North America from the Miocene onwards, and the species has lasted for nearly 20 million years.1

Kansas, Missouri, Nebraska and Tennessee have made the channel catfish their official state fish.1

Mite-breker

Mite: Channel catfish barbels can sting when touched.

Waarheid: The barbels cannot sting. The spines on the pectoral and dorsal fins are the only part that can cause injury.1
