Thread: Older Fish Reproduction

I have something that was a little baffling to me on the fish I caught from Tenkiller the other day. She was 18" long and 2 1/2 lbs., but had very little in the way of eggs in her. So my question is do fish not reproduce as much when they are older fish? The egg sack wasn't bloody like she was ready or had been dropping eggs yet. Had this fish been full like one would think then I figured she would have gone closer to 3 lbs. Just long and skinny. Here's the pic of it again.
