Yeah, It's a nice fish.
Most places the limit is 2 fish 60cm to 110cm.
BUT...In the ACT (ie Canberra) the size limit is 55cm to 75cm with a bag limit of 1.
If Mitch has an arm length about the same as mine, then his cod is probably a dinner fish. So I was just asking if it is a keeping size.
How big do they grow? Well, these days to about 1.8m (180cm or 6 foot). In the old days much bigger.
Don't ask me why the ACT has different limits...I don't know 😊
