   Can anyone steer me to a good chart, that shows approximate weight , using the length of the fish ? I caught a 35" black drum, this afternoon, and I'm "guesstimating" it was 20 pounds. I have a "fairly accurate" scale.....or should say "HAD", as the batteries were left in it over the summer, and ruined it when they leaked (oops !).   Thanks !

Sort of depends on who landed the fish...

If it was you, your estimate of 20 pounds would be accurate in my opinion...

If I caught it, you could easily add 50% to the weight...😁😁😁

Nice catch!

The first rule of fishing is to fish where the fish are. The second rule of fishing is to never forget the first rule.

Lenght/weight converion Texas marine species identification :D it's good,,,but if the fish is shaped different,,,,,the weight is different,,,,I get 100yr old spring scales on ebay $8 to $15 and that work great ;D

It varies by species ! I only know halibut and salmon. I wonder if the salmon one will work for yellow tail? I will try it next year at Cedros. Length x girth squared and then divide by 800.

HA! And if you caught it & I netted it I'd say it was probably 10lbs.  ;D
Love those open face spinning reels! (Especially ABU & ABU/Zebco Cardinals)

   Thanks, everyone !  And, Benni, I have a couple of those old Zebco "De Liars" scales.........in tackle boxes that are 'home" in Illinois ! It always seems that "what I want" is NOT "what I packed" ::)! The way the weather is looking, it will be a while before I get to go back out on the beach......lots of rain coming!   Thanks again !..................Crow

the only formulas that sorta' work, are species-specific & you need length+GIRTH

alantani

for tuna, we use length x girth x girth (in inches) divided by 800. 
send me an email at alantani@yahoo.com for questions!

Alan: That's the same formula we use for salmon. Its works well and is close except for the odd fish that is really long and skinny or really short and fat.

  Generally speaking,  you need to first know your audience   ,  it takes a fantastic story to usually impress your friends.  Adding 20-30 % is not really hurting anything, except maybe the 12 year old rule? ;)

   Since the advent of television people are easily bored.

Same formula we use for muskies and it is pretty accurate up to 50" but is way off after that.

You know that moment when your steak is on the grill and you can already feel your mouth watering.
Do vegans feel the same when mowing the lawn?

Got another drum, this afternoon, and using the "conversion table", a 38 incher should be 27 lbs, 13 oz.

My spring scale reads 28 lbs., so, I think the "table" is pretty close,
