Most catfish species are opportunistic feeders, while others are omnivores. They hunt their food from the surface down to the deep.
They hunt their food from the surface down to the deep. They have special taste buds and organs that can detect food despite low visibility.
To learn more about catfish diet, here are five amazing facts to know about this species.
1. Male catfish watch over the eggs and young fry, but they eat them as well
The parental skills of a male catfish depend on whether they are starving or not. Males are in charge of guarding the eggs and young fry until they are old enough to survive on their own.
Before growing into a full adult, the young fry feeds on anything they can get their mouths on. Small invertebrates like hellgrammites, dragonfly nymphs, caddis fly larvae, and worms are among their favorites at this stage.
2. Their diets become more specific as they age
Different species of catfish have different preferences as they grow older. For example, flathead catfish do not eat anything other than live smaller fish.
Whereas channel cats and bullheads eat live fish, but they are carrion eaters as well. This means they won’t say no to dead fish at the bottom of the stream either. Aside from this, they also love to feast on clams, frogs, and crayfish.
Certain species like flatheads do not eat anything but meat. Channel catfish, on the other hand, eat plant material to supplement their diet in the absence of other fish.
3. Their whiskers help them to find their food
Aside from giving them their unique look, a catfish’s whiskers have biological functions as well. They navigate their way to find the food especially at night when there are fewer predators roaming about.
At the same time, nighttime feeding also allows them to ambush their prey easily. Next time you see a catfish, notice how the whiskers touch the ground when they swim deep. This method helps them find leeches and worms that are hiding under the sand or dirt.
4. Farmed catfish get nutrition from specially formulated feeds or pellets
For catfish grown in ponds, nutrition comes from manmade feeds. Protein concentration that ranges from 28% – 32% is the ideal nutritional requirement for farmed catfish.
In accordance with their feeding pattern, farmers are recommended to use pellets that float or sink depending on the temperature of the water. Specifically, the ideal pellets should float when the water temperature reaches 65 degrees Fahrenheit.
When it drops to 60-65 degrees, slow sinking pellets are recommended. Finally, sinking pellets are more preferred when the water temperature goes below 60 degrees.
5. Catfish can remain undetected by their preys
A study published in 2001 showed that before being eaten, preys that have been stalked by catfish did not exhibit any avoidance at all. This means that aside from their high sense of taste, feel, and smell, catfish also has the ability to trail their prey without being detected.
