Hi Andy,
I just read your posting as regards tagging
& thought you maybe interested in the following
On the 20/02/93 I tagged a small Black Marlin & Released it Just off Cape Moreton Tag No.S 76527 Weight at release was 20.Kgs
This Fish was Recaptured on 05/07/93.& travelled
3600 Km North. Time out 135 days & weighed 30Kgs.
I contacted N S W Fisheries to enquire who caught this fish They replied a Japanese" Purse Seine vessel "The Genpuku Maru #81
It was a dissapointment to see a professional catch
this fish & not a rec. angler.But it does show tagging fish
does no harm to the fish if handled correctly Cobia Kev
