just google suntag its under the link info-fish (dnt know how to put a link on here)
tagging stater kits cost about $35 all you need to start tagging
there was recently a jack that was recaptured in coffs harbour after being tagged in caloundra i cant find the mag i read about it in but i believe it was on the loose for over a yr and a half and was tagged at 38cm and recaptured at 46cm travelling over 500km in that time
so they dont stay in the esturies till there 50cm plus and leave for the reefs for ever
jack sh#t is known about these fish in the wild
so the more of us tagging them the quicker we can find out more about them and if they need help which i sincerly doubt they do
cheers shin
