I was just curious and wondered how do you tell a catfish's age?
The Freshwater Angler says this about channels:
"Channel cats more than 20 years old have been recorded, but most live less than 10. They grow slower than both flatheads and blues.
Growth rates have been studied throughout the fish's range and show extreme variability from one body of water to another. A 5-year-old channel cat from the Mississippi River in Iowa, for example, runs about 16 inches long. A same-age fish from Lake Havasu, CA is slightly more than half that length - 9 inches. A 20-inch channel from Manitoba's Red River is probably age 9, but a 9-year-old cat from the St. Lawrence River in Quebec is only 13 inches. Growth rates are determined by a number of factors, including abundance and type of forage, quality of habitat, length of the growing season and competition with other fish species."
They have a couple of charts I recreated, you can find them here:
You can check out this thread for more info
If you haven't already, check out the links topjimmy suggested. He did a nice job with the age & growth charts.

Very nice table you put together, job well done.
very well researched
I like it. Great job. Even if you don't have a scale to weigh it you can measure the length and get an idea of the weight. Again..Great job!
Good job on the charts. I don't have about a scale and this will help.
The chart is a great help. Thanks.
NICE JOB on the chart! Thanks
Nice chart. I have seem a few like it, some of the others take into account the part of the U.S. that the fish are in. The general conscious is that the fish grow a little faster in the more southern states due to weather and amount of food.
Our european catfish can live nearly 30 year for the biggest one.
