hi everyone
iam working atm offshore on a oilrigg of karratha ,been watching a lot of gts for the last couple of months ,
looks like there are some gt,s that are always here and it gives me a good opportunitiy to see there behavours.
there is a school of smaller gt here around the 10 kg mark but also around 6 gts around probably +20 they always travel as pairs one black one silver even in the smaller ones are sometimes in pairs ,the king out here is on pair ,were i called the siver one BB for big bertha ,and that one is a fish of a lifetime i recon 50 kg .
do gt change there color depending on mood or sex ?
thanks for any answers ,,and no fishing allowed and a 500 m exclusion zone for boats
