 Quote:
Blue catfish in these rivers steadily increase in length over a fairly long period of time (through age 15). However, they put on weight fairly slowly for the first several years of life, after which, as fish make a diet shift to larger, energy-rich, prey items, the rate of weight-gain increases dramatically. Blue catfish in the James River attain only 5 pounds on average by age 8. Then, with a rapid increase in growth, they average 10 pounds at age 10, 20 pounds at age 12, and 30 pounds at age 13. Fish in this population are known to reach 50 pounds by age 11, although age 13 � 14 is more typical.
