How Much Does a Flathead Catfish Grow Per Year?

The growth rate of flathead catfish can vary depending on factors such as food availability, habitat conditions, and individual genetics. On average, flathead catfish tend to grow at a moderate rate compared to some other fish species.

In their early years, flathead catfish can experience rapid growth. During their first year, they can reach lengths of around 6 to 10 inches (15 to 25 centimeters). However, as they mature, their growth rate slows down.

In favorable conditions, adult flathead catfish can grow around 1 to 2 pounds (0.45 to 0.9 kilograms) per year. It’s worth noting that exceptionally large individuals may have slower growth rates compared to smaller ones.

Flathead catfish are known for their ability to grow to impressive sizes. The world record for the largest flathead catfish caught on rod and reel weighed over 123 pounds (55.8 kilograms). However, it’s important to keep in mind that such large specimens are relatively rare, and most flathead catfish caught by anglers are much smaller.

How often do flathead catfish eat?

Flathead catfish are opportunistic predators and have a voracious appetite. They are known for being active feeders and have the ability to consume a wide variety of prey. The frequency of their feeding can depend on factors such as water temperature, availability of food, and individual metabolism.

In general, flathead catfish tend to be more active during warmer months when water temperatures are favorable. During this time, they may feed more frequently, often during dawn and dusk or at night. They are primarily nocturnal or crepuscular feeders, meaning they are most active during low light conditions.

Flathead catfish have an opportunistic feeding behavior and will consume live fish, insects, crustaceans, mollusks, and even small mammals or birds if the opportunity arises. They are known to be sit-and-wait predators, patiently waiting in cover until prey comes within striking distance.

The frequency of feeding can also depend on the availability of food sources in their habitat. If food is abundant, they may feed more often, while during periods of scarcity, they may adjust their feeding behavior accordingly.

How much does a flathead catfish eat?

In general, flathead catfish have been observed to consume approximately 2-3% of their body weight in food per day. This means that a 10-pound (4.5-kilogram) flathead catfish might consume about 0.2-0.3 pounds (90-135 grams) of food daily. However, it’s important to note that these are rough estimates, and individual fish may exhibit variations in their feeding behavior.
