Splake

[Yellow_Perch]

depending on your area, but they do grow fast and big since it is a hybrid of lake trout x brook trout..but im going to say they can get 20lbs and 16 inches but a 20 lb splake is hard let alone a 9lb splake is considered a "trophy"..

All that i know is that they were designed to grow very fast so that lamprey would have a harder time killing them while they are young. I know they grow around 2-3 times faster then brook trout though
