With respect to the post below and the Perry fish, there
seemed to be some interest for a formula that would accurately
predict the weight of a record class bass. Until this past
year, there were no formulas that could do this. The standard
formula used by most anglers (weight = L x G x G divided by
800) tends to over-estimate weight by 15 to 45 percent. Other
formulas either under-estimate or provide too wide a spread in
Last year (at the request of In-Fisherman magazine) I
collected data from over 67 certified fish over 14.25 pounds
(most fish were over 16lbs) and developed a formula
specifically for this class of fish. This was mainly done to
prove the Leaha Trew fish was a hoax.
Anyway, the formula that was developed will accurately predict
the weight of a bass of monster proportions within +/- 5% (for
95% of the fish population). The formula is:
Weight = Length (Raised to the power of 0.68) x Girth (Raised
to the power of 0.79) divided by 7.0
If you are interested in reading more about the development of
this formula, it was printed in In-Fisherman's Bass Guide 2005
and on BassFanArmy.com. Rob has a copy of the article for
print too but has not had the time to upload it due to all the
work he's been doing on the site lately.
If you have any question, feel free to ask and I'd be happy to
answer any of them.
