Just an FYI...growth rates of channel catfish in Utah Lake have been conducted. But, I don't think it has been done for many years. I am reading one such study done where growth rates were listed this way: "The following lengths at ages on through 12 years based on the the body length (total length)-spine radius relationship: 64, 146, 197, 256, 320, 365, 402, 457, 474, 487, and 489 MM. The length-weight relationship is expressed by the equation Log W = -4.814 + 3.025 LogL." It was also determined that fish in Utah Lake reached sexual maturity as early as age 4 and all by age 8. So, if the catfish population is healthy (which seems to be the case) harvest of fish 8 years of age and older is ok because enough remain to continue replenishing year classes of fish.
But, that data is fairly old and the lake has changed since that study was completed. Nevertheless, I wouldn't be surprised if those numbers are still close to actuality.
