Estimating Tuna Size

Thought I would put this formula out there, since there is always alot of back and forth on sizes of fish - especially when your dealing with fish (hopefully) that are too big for the tackle shop scale.

(Length X Girth X Girth) / 800 = fish weight

This should give you the weight within 10%. This is especially effective on tuna, as they don't normally have any funky shapes (like a protruding belly on a big bass).

This is a straight line measurement for the lenght, not a curved, so you would not use a flexible tape for the length, but you would use one for the girth.


Hope there are lots of sushi parties for everyone this year!
