Bonefish size estimation

[gammarus]

Rainbows, no problem. Steelhead, easy. How do I estimate the size of my bonefish. I can tell the length by looking at it but weight, I'm not sure of. Is there a length-girth formula like steelhead?

Try using the same formula.

18" = 3.5lb
20" = 4.1lb
22" = 5.1lb
24" = 6.0lb
26" = 7.2lb
28" = 8.6lb
30" = 10.8lb
32" = 13.0lb
34" = 15.6lb
36" = 18.0lb
40" = Dreaming!

Chart is from Kaufman's Bonefish Book. I've found you can often add about 1lb for Pacific bones from 28" and up (as far as 32" anyway, i'd like to check some bigger fish)!

The measurement is from the fork in the tail, not the overall length - right?

[Bob Bergquist]

Yes sir, but I like to measure to the tip, then back to the fork, adds inches and pounds!
