    Are there physical characteristics that allow you to age channel cats? And does anyone know their lifespan?

    There are little bones in their skull called otoliths which grow rings with age like a tree. Other than discecting the fish, and having a complete understanding of this, I think it would be next to impossible to determine the abe of a fish.

    Unfortunately, you can't look at a fish and guess it's age as close as you can look at me and guess mine. Think our game department said a flathead don't start to spawn until they are around 7 years old... and they put something like a minimum length of 19" on the flats to be sure they do get one or two breeding seasons before they are taken to dinner. So, a 16 inch flathead is probably about 7 years old. Doubt that helps, but without having a microscope and observing the rings in the olith (sp) thats as close as your gonna get. Oh, flats supposedly grow slower than channels and blues.

    I believe it, under good conditions, I could see them living a very long time kinda like a reptile.

    No way to tell the age without cutting the head apart of doing a cross section on the fins.

    I have a chart that I use to "age" my channel catfish. Unfortunately I don't think I can post it without a copy write violation warning. I splits it up into Northern and Southern fish and it gives approximate
    avg. length and weight relative to the age of the fish. I believe that it is fairly accurate but the version I have only goes to about 8-10 years of age. I can see if I can find a more extended version and get back to you. I'm not sure how large the margin of error is but a chart is available.
