A fisherman from South Australia's rugged west coast, who attacked and landed a shark with his bare hands, does not recommend others do the same.

Phillip Kerkhof, 42, from Louth Bay, admits his judgement was clouded by a few beers and vodkas when he saw a 1.3-metre bronze whaler shark chasing his squid lures off the local jetty on Monday night. Mr Kerkhof, a former tuna fisherman in Port Lincoln who now works in the building industry, climbed down a ladder and stalked the shark in the shallows before sneaking up behind, grabbing it around the tail and wrestling it on to the jetty.

"I had both hands wrapped around his tail and he was thrashing around," Mr Kerkhof said yesterday. "I brought him back towards the steps and hurled him up on to the jetty."
