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

Ekhaya
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
Ubude

Ubunzima
910 g ukuya ku-26 kg (2 lb ukuya ku-57 lb)1
Esona santya siphezulu
malunga ne-8,5 km/h (5,3 mph)

Sitya ntoni?
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

Indlela yokusiqaphela

  • 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

Amandla etyhefu yokuluma nokuhlaba

Amava anetyhefu

Amava abukhali aphethe ityhefu. Ukusinyathela okanye ukusibamba kubuhlungu.

Ityhefu yaso yokuluma okanye yokuhlaba yenza ntoni?

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

Siyingozi kangakanani ebantwini?

Ingozi ebantwini: KubuhlunguKunokuba buhlungu ngokwenene, kodwa phantse akusoze kube kubi kakhulu.

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

Senza ntoni xa soyika?

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

Ukuba amava aso ayakugwaza

  • Faka inxeba emanzini ashushu, ashushu kangangoko umntu angakwazi ukunyamezela ngaphandle kokutshiswa (wavavanye ngesandla sakho), imizuzu engama-30 ukuya kwengama-90. Fumana uncedo lwezonyango, ingakumbi kwii-stonefish nakwii-stingray.

Soloko utsalela inombolo kaxakeka kuqala (112, 000, 911). Esi sisikhokelo soncedo lokuqala ngokubanzi, asilocebiso lwezonyango. Iziseko zoncedo lokuqala

Hlala ukhuselekile

  • Ungaze uchukumise, ubambe okanye uqhule isilwanyana sasendle, nokuba sincinci, kwaye nokuba sibonakala silele okanye sifile.
  • Sinike indawo. Ukuba udibana naso, hlala uzolile, buyela umva kancinci kwaye usiyeke sihambe ngendlela yaso.
  • Ukuba amava aso ayakugwaza: hlala uzolile, musa ukushukuma, tsalela inombolo kaxakeka (112, 000, 911) okanye uye esibhedlele ngokukhawuleza. Khumbula ukuba sasikhangeleka njani, ifoto iyanceda.

Asikuzingeli. Sisebenzisa ityhefu yaso ukubamba ukutya okanye ukuzikhusela, kwaye singakhetha ukuzimela. Okungakumbi malunga nokuhlala ukhuselekile

Iinyaniso

1

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

2

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

3

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

4

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

5

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

6

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

Umqhekezi weentsomi

Intsomi: Channel catfish barbels can sting when touched.

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