;):D

A On line scale hmm? Never heard of such a thing- Do You type in the fishs size & species & it gives you a computer estamation then?


Themachanical scale i use in reloading is very acuratte never messed with the electric ones but was thinking of getting one for fish

RE: Fishing Scales
 

Therte is a formula some use up here to guess the wieght. I am not sure, but it is something like taking the measurement of lenght and times it by the gerth. Then take and divide by .400 or something like that and it will put you in the ball park pretty closely. As I said I am not 100% sure what that formula is that they use but it is along those lines.

RE: Fishing Scales
 

Here is one from the Florida Freshwater Site.
A quick, though very rough, estimate of torpedo shaped fish like young bass can be obtained by using: Total Length (in inches)-squared, times girth (in inches) divided by 1200. A 22" long bass with a girth of 15" weighs about 6.1 pounds using this formula.

Another common option used for estimating bass weights is: Girth (in inches)-squared, times length (in inches) divided by 800. A 22" long bass with a girth of 15" weighs about 6.2 pounds using this formula.

I just worked one out ...

I tried a bass measuring 20 inches...with a 13 " girth

Let's square it 20 length squared
x20
-------
400

times girthx 13"
------
5200 divided by 1200 = 4.3 pounds

There, that wasn't that hard.;)

Purchase a sewing tape{Under 2.00 at Walmart sewing department}and you don't even need a scale. folds up real small {About 1 inch circle in tackle box.}
Length times itself times girth divided by 1200= weight.

RE: Fishing Scales
 

i brought mine (berkley) to work with me tonight, using weights that we calibrate scales with mine is very close,

1 # weighed one pound.
1.5 pounds weighed 1lbs and 8 oz.
5 pounds weighed 4lbs. 15 3/4 onces.
10 pounds weighed 9lbs. 15 oz.

i weighed these items (weights) 3X and the weight was the same each time, for me i can live with a scale that reads off 1ounce @ 10lbs., and they do what i need. i bought them to cull tournament fish, and have a cumlitive weight, so far i am happy with mine who knows maybe i got the good one out of the bunch, even though i have always been skeptical of cheap electronic scales, so far these have been a great tool for what i needed, if i was just using it to weigh one fish, i would go with a mechanical, but i can store up to 7 fish on this and know which one is the lightest and which is the heaviest by pushing one button, saves me fishing time, try putting 5 fish in a livewell that all are around 3 pounds, then catch a five pounder, which one of those 3#'ers are you gonna cull, i know that i am culling the smallest fish W/O a doubt, i also like a balance beam, but it eats up time[&:]

RE: Fishing Scales
 

Fish math eh?:D( math was never this fishs fav subject;)) Intresting tho -Thanks Phil& C7 for the explanations.

So it gives a pretty close estamate- and is species specific& or shape& younger fish only?
Like humans some of them fish seem to increase in grith mostly only with age hmm;)

But unlike humans tho i guess they wont at least get shorter in old age?

For you maybe:D- just keep the algebra etcaway& i should be ok.

Mr. Fish,,

Mr. Fish ..after 6 years of college I tested out 5th grade for math.:(
This is why I teach elementary.LOL The formula is very easy.
multiplication ...multiplication...divide.....:)
