A tog that big would be well past 20.. perhaps 25.. the very biggest tog over 20 pounds are in the 30 year + range... The average fish we catch say between 15- 18 inches are between 6 and 10 years old.. Personally, I am not sure they can withstand the pressure they are under... Nothing else to fish for in winter these days, puts the heat right on the broad shoulders of tog.. Also the fact that the live market for sushi/sashemi for them is relentless.. I fear hard times ahead in the blackfish population... I hope I am dead wrong... bob
