What do catfish eat?
Catfish can eat fish, snails, frogs, clams, and mollusks in their natural habitat. They can also eat other smaller mammals like birds that they catch off the surface of their pond.
Besides the food they eat in their natural habitat, they also feed on commercial feed when in captivity.
Below is a perfect description of some of the kinds of food that catfish can eat;
1. Commercial fish food:
Commercial fish food is the ideal food to feed catfish in captivity to help them grow faster and healthier.
For the baby fries, feed them high-protein fish flakes.
But for larger catfish, pellet commercial fish foods are perfect to keep them healthy.
2. Catfish can feed on smaller fish:
When next you think “what do catfish eat”, know that they eat fish too.
They usually eat fish that are smaller than them.
Because they are scavengers, they also nibble on the carcasses of larger fishes.
Gladly, catfishes will eat insects of all types.
This includes crickets, grasshoppers, earthworms, dragonfly larvae, water beetles, fly larvae, and mosquito larvae.
However, it’s mostly the young catfish that feed on aquatic insects.
Large catfishes feed on the crustaceans they find in their natural environment.
Crustaceans include animals such as crabs, decapods, lobsters, crawfish, water flies, water fleas, etc
5. Aquatic plants:
Catfish do eat plants.
Aquatic plants such as algae, lotus plants, water lettuce, etc are eaten by catfishes.
6. Fruits and vegetables:
Catfish farmers are often advised to offer their fishes fruits and vegetables.
This is to ensure that they get enough nutrients.
You can offer them raw or cooked veggies.
Catfishes prefer fruits such as apples, bananas, strawberries, broccoli, cabbage, etc
Blood? Are catfishes vampires?
Well not literally, but some species such as the Candiru are parasitic.
The Candiru will latch on its prey and feed on its blood.
8. Small animals:
Catfishes are good at hunting and eating small animals such as mice, lizards, small birds, frogs, and many others.
When either of the above falls into a catfish pond, they are in for some scavenger hunt.
9. Dead animals:
Catfish also feed on dead animals also known as carrion.
So, next time you find a dead catfish in your pond, instead of removing the carcass, you can just allow your fish to feed on it.
Also, if you run a poultry farm and you experience a lot of chicken mortality, you can dump the carcass in the pond for your catfish to feed on.
