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

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

Kaj je?

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

Kako jo prepoznaš

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

Moč strupa

Ostre bodice nosijo strup. Če stopiš nanjo ali jo primeš, boli.

Kaj naredi njen strup, ko ugrizne ali piči?

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

Nevarnost za ljudi: BolečeLahko zelo boli, a skoraj nikoli ni resno.

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

Kaj naredi, ko se prestraši?

It can lock its pectoral spine as a defence, and the serrated, poison-bearing spine helps to deter predators.1

Če te zbode z bodicami

Rano daj v vročo vodo, tako vročo, kot jo poškodovanec prenese, ne da bi se opekel (preizkusi jo s svojo roko), za 30 do 90 minut. Poišči zdravniško pomoč, še posebej pri kamnitih ribah in morskih bičih.

Ostani varen

Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
Če te zbode z bodicami: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

Dejstva

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

Razbijalec mitov

Mit: Channel catfish barbels can sting when touched.

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