Flathead Catfish Growth Rate
In comparison to other native flathead catfish populations in the southern and midwestern United States reported by Kwak et al.
Flathead catfish growth rate. Channel catfish grow fine without feeding in most ponds when stocked at 100 or fewer per acre. Fish in the NECFR grew to a total length of 700 mm by age 7 whereas fish in the Neuse and Lumber river populations reached this length by 8 and 10 years respectively. For example a growth assessment of channel catfish in Lake A reveals fish are 6 inches at the end of their first year of growth age-1 85 inches after their second year of growth age-2 and 11 inches after their third year of growth age-3.
Reservoir flathead catfish populations is still lacking. But looking at the chart they grow much faster at a younger age and start to grow slower as they get older. Growth was significantly faster in the Northeast Cape Fear River NECFR than in the Lumber and Neuse rivers.
Biologists have always assumed blue channel and flathead catfish grow faster in the South where the growing season the time when water temperature exceeds 70 degree lasts 6 months or longer compared to northern waters where sufficient. The time it takes other species of catfish such as flathead and blue catfish to reach full size in rivers ponds and streams will depend on climate food source availability and the body of water they inhabit. Primarily a diet of fish.
Apr 30 2018 Initial channel catfish stocking rate usually is 100 fingerlings per surface acre ie 10 per 110 acre in ponds that are not fed or fed inconsistently. Up until the fish get to the age of 10 years old they grow at a minimum average of about 3 inches per year. On average a flathead catfish in the upper section reached trophy size 350 in at 206 years while flathead catfish in the trophy permit section reached trophy size nearly three years quicker at 177 years.
Their first year of age they averaged 46 inches. Flathead catfish feed mainly on fish and may have a place in the management of small lakes that have an overpopulation of bluegill. Apr 26 2017 Growth rate assessments usually rely on what biologists call length-at-age data.
Aug 18 2009 Average weight gain by a flathead in the state of kentucky is between 3-5lbs per year so they can get big quickwinkNo wonder they eat big baits. Compilations of growth rate data for this species across its native range have shown that growth is highly variable within age groups popula-tions and among waterbodies and shows no latitudinal effects Jackson 1999 Kwak et al. Flathead catfish as well as the white catfish are not recommended in a farm pond.
