Peter Morse or "Morsie" whom we have seen on River and Reef before (use our search function)  recently sent me some information on his current world record application. He captured a Southern Bluefin Tuna (thunnua maccoyi) on 10kg /20lb tippet at Pedra Branca 40 kilometers South of Tasmania in late April. Peter said the fish "went 25kg on the dot" and for our USA readers that is fifty pounds. It took Morsie 40 minutes to subdue the fish and beat the current record of Alex Langley's fish that was 16.2 kg. Alex caught his fish at Tasman Island in May 2002. Peter summed up his trip and capture by saying "If nothing else, apart from a great experience down there in the southern ocean in a 7 metre tinny, it was bloody good eating". A tinny is what Australians call an aluminium boat.
The all tackle record for this species is a whopping 158kg or 348 lb so there is room to move for those wanting to fish the wild Southern Oceans.
