Telling the truth- GT weights

Gamefishing Asia’s fundamental operating principles are ethical sport-fishing, conservation and honestly in all our dealings.

Especially in regard to GT’s weight, measurements and sizes, yes we do know that after a hard fight with a great Geet once you see it on deck with the adrenalin still high there is the tendency to over estimate the weight and given how hard GT’s fight they seem a lot bigger than they actually are.

There is also the time factor of getting the fish back into the water set to swim away safely after the hook removal and photographs, the more GT’s released the better for the fishery.

Is there a simple way to do this, on a rocking boat and fast? the answer is yes, all you need is a good tape measure and two simple measurements given below:

1 Length from Centre of lower Jaw to fork of tail in centimetres (cm.)
2 Girth just behind pectoral fin in centimetres (cm.)

Shown again in the pictures below to highlight

Picture showing girth measurement behind pectoral fin above (remember to double if you measure only one side)

Now that you have the measurements how do you get the weight, there is a simple formula that can be used to calculate weight and has been proven time and time again to be accurate to +/- 5% here it is below:

Length x Girth x Girth x 2.74/100000 (fish to 30kg)
Length x Girth x Girth x 2.70/100000 (fish to 40kg)
Length x Girth x Girth x 2.60/100000 (fish to 50kg)

All measurements in cm

A lot of anglers are surprised at the actual weights of the landed fish, but it is our opinion that the real weight of the fish makes landing that monster that much more of a valuable and prized catch.
