Calculating fish weight?
I have heard that there is a quick and dirty method to calculate the weight of a largemouth bass with out having to plug in the girth. I think it is something like -
length (inches) * length * length / 1200 = __ lbs Can someone confirm or correct this? |

That can't be right. That's like saying you can calculate the area of a rectangle by multiplying length x length x length/1200. If the rectangle is 2 inches wide, the area is obviously different than if it's 20 inches wide. You've got to have a "y" dimension figured into your calculations.

An average 12 inch long bass is approximately 1.5 lbs and this method says it is 1.44 lbs. I am just looking for a quick and easy method to figure out the approximate weight of the fish I catch when I am waist deep in water using my chest waders. I can measure the length of the fish rather quickly but the girth is hard to measure while holding the fish, the rod, and the tape measure. If I ever hook a 5lber or more, I will take it to the bank so I can get some photos and proper measurements. |

heres the link we all use
http://www.bassfishin.com/bassfishin...cement.php?f=6 not all fish that have the same length will weight the same, you need girth and length in the equation You can always just take a piece of fishing line and wrap around the girth, then lay it flat and put the ruler up to it for girth, works on the lenght too |

Yeah. I saw that link but it is difficult to measure the girth of the fish when I am in my chest waders. Just not enough hands. I guess I may have to invest in a digital scale that hooks onto my vest. Or better yet, a retractable soft plastic tape measure (one that only needs on hand to use).

Golf,
It's simple. Have your girlfriend stand on the bathroom scales, preferably nekkid, and take note of her weight. Then, hand her the bass and note the new weight. Subtract the first figure from the second and... Voila!...231 pounds less 222 pounds= one 9 pound bass. See? Easy! My eyes! My eyes! Lancer6 |
