[quote Hazzy_HazbournCrazy, the different growth spurts that they have; the one fish growing 3" and another 1/4" in the same time period. Like teenagers vs. duffers; the young ones gain height and the old ones gain width.[/quote]
Remember, fish are not like mammals. They [fish] are "indeterminate" growers. Mammals are "determinate".
Fish are very "plastic". This is why we preach all the time the importance of having fish populations in the zone of maximum growth rate. Fast growth rate = bigger fish. When growth rates slow, due to population increases, average size fish go down. Some fish, like the first tagged fish, may experience periods of very slow growth rates followed by other periods of fast growth rates. That 1/4" growth over the last two years might change next year with 3 new inches, followed by another 3 inches the next year, followed by 0 inches for the next. The other fish (3") might have added that whole 3 inches in 1 year.
Fish are amazing.
Great pictures. That looks like fun. I wish Bear Lake wasn't a 6 hour tow!
