Blue Catfish Growth Rate

The goal is to gather data for a three-year study on blue catfish sizes population and growth rates.

Blue catfish growth rate. 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. Lake Barkley 218 yr. Kentucky Lake 214 yr.

Blue catfish grow slowly during their first few years of development and more quickly as they age. Marys Virginia Institute of Marine Science suggests that continued warming of Atlantic coastal waters may enhance the spread of invasive blue catfish. Feb 11 2020 The study was done on a river with tagged fish.

B Blue Catfish are a distinct strain of blue catfish that exhibit fast growth aggressive attitude trophy potential and great table-fare. Channel catfish grow fine without feeding in most ponds when stocked at 100 or fewer per acre. Feb 24 2021 Their results show that warmer water temperature has a positive effect on the biology of blue catfish under salinity conditions often encountered in estuarine waters.

Growth rates vary from river to river depending on how crowded the area is and how much food is available. Trouble is blues are so effective we have found they can become a significant player in the food chain thus a negative factor when big bass are. Nov 12 2007 Heart of the Hills researcher Dave Buckmeier said the two years Splash spent in captivity at the Texas Freshwater Fisheries Center in Athens may have been responsible for fuzzy growth rings on the outer edges of her otoliths.

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. A new study by researchers at William. Apr 26 2017 Growth rate assessments usually rely on what biologists call length-at-age data.

Feb 26 2021 At salinities up to 7 psu mean growth rate body condition and consumption rates were all higher at 72 degrees than at 54 degrees. Furcatus brood fish are collected from the wild. They saw growth rates up to 8lbs per year 3-6 were most common up to about 24-28 pounds.
