Unfortunately, I can't help you on the growth rate. What good are all these records if I can't quickly produce usable information and nice graphs, huh?

As far as maximum size goes - I have some 16-year-old males who were fed heavily at various times of their lives, but even so, none are much over 6 feet long today. At their heaviest, some approached 20 pounds in weight, but I don't allow them to pig out like that any more.
