# Channel Catfish (*Ictalurus punctatus*)

> The channel catfish is one of the most popular sport and farmed fish in North America, recognised by barbels ('whiskers'), smooth scaleless skin, and a forked tail. Native to central and eastern rivers and lakes, it grows to 10–25 kg (22–55 lb), tastes mild, and uses taste buds across its body to find food.

## Barbels and taste

Channel catfish have four pairs of barbels around the mouth plus taste buds covering the body — especially the whiskers — allowing them to locate food in murky water at night. They are opportunistic bottom feeders eating insects, crayfish, small fish, and plant matter.

## Spines and defence

Sharp spines in the dorsal and pectoral fins can lock in place and inject mild venom, deterring predators and unwary anglers. Handling from below and using lip grips reduces sting risk. Spines also help catfish lock into crevices.

## Aquaculture and sport fishing

Channel catfish are the top farmed fish species in the United States, raised in ponds across the South for food markets. Anglers target them with stink baits, chicken liver, and cut bait — they fight hard and tolerate low oxygen better than many game fish.

## Range and introductions

Native from southern Canada through the Great Lakes and Mississippi basin to Mexico, channel catfish have been stocked widely for fishing and farming. They can outcompete native species where introduced outside their range, requiring careful management.

## Frequently asked questions

### Are catfish whiskers dangerous?

The barbels are harmless feelers. The danger comes from sharp fin spines that can puncture skin — not from the whiskers themselves.

### What do channel catfish eat?

Almost anything on the bottom — insects, worms, crayfish, small fish, and plant material. They hunt mainly at night using taste and smell.

### How big do channel catfish get?

Most caught fish are 1–5 kg, but large river fish can exceed 20 kg. The record is over 25 kg.

### Can catfish sting you?

Fin spines can puncture and cause pain and swelling from mild venom. Handle carefully or use pliers to remove hooks.

### Where are channel catfish found?

Native to central and eastern North America; farmed and stocked in ponds across the United States and introduced in Europe and elsewhere.
