  • This species is notable for its forked tail and its upper jaw which is longer and overlaps the lower jaw.
  • They inhabit lakes, larger rivers, and streams especially on mudflats, clean sand, gravel or stone bottoms. They can also be found below dams.

What do Blue Catfish Eat?

What Do African Catfish Eat?

  • The North African catfish is commonly found in Africa, some parts of Asia and Europe.
  • This species inhabits a plethora of freshwater environs which include lakes, pools, and ponds.

How Do Catfish Hunt?

Catfish use a wide array of hunting techniques to find their prey.

How Do Catfish Hunt?

  • Predation has been noted to be successful when slow benthic organisms are targeted.
  • One strategy some species use is the pack-hunting technique where there is a collaboration of several catfish.
  • Herding is mostly used where their preferred prey is trapped and later ambushed. Catfish can also hunt prey individually by targeting prey and capturing it.

When Do Catfish Eat?

Different catfish species are active during different times of the day.

  • Some species are nocturnal, preferring to come out at night to feed.
  • An excellent example of a nocturnal feeder is the African catfish.
  • Some species display diurnal or crepuscular activity.

How Often Do Catfish Eat?

How often catfish eat depends on many factors, one being age.

  • Younger catfish need more energy to grow compared to the already mature species.
  • As such, they will tend to eat as often and more compared to mature catfish.

What Eats Catfish?

Thanks to their abundance and their poor motility in land and water, catfish are preyed upon quite easily by a vast range of organisms.

What Eats Catfish? Crocodile

  • Examples of organisms that predate on catfish include crocodiles, some Bird Species, Storks, Fish Eagles, leopards, and of course, humans!
  • Some catfish species are eaten by other catfish (cannibalism).

Where do Catfish fit in the Animal Food Chain?

Catfish play an instrumental role in the animal food chain.

  • They feed on a large number of smaller organisms (mollusks, aquatic insects, crustaceans, and small fish).
  • Because of this role, they help keep the local population of these organisms under check.
  • Catfish, especially the channel catfish species, are preyed upon by organisms like humans thus providing them with vital nutrients necessary for survival.
  • Catfish also feed on carrion from dead organisms. In this role, they help rid the ecosystem of dead organic matter, thus providing a clean ecosystem for other organisms to thrive.

In a nutshell, the existence of catfish confirms the presence of a thriving ecosystem.
