A fisherman caught an 80kg shark when he was netting crabs, 200 meters from Quy Nhon beach in the central Binh Dinh province this morning.
The fish, thought to be a juvenile great white shark, was stuck in the net of 36-year-old Nguyen Thanh Hai.
Hai said two strong men assisted him to bring the shark ashore.
“We often call it great white shark because they are violent,” said Nguyen Van Nhan, 55, a local experienced fishermen.
Swimmers were attacked in the waters off Quy Nhon beach more than 10 times between 2009 and 2010 in which at least two cases juvenile sharks were thought to be the culprits.
Last April, authorities in Quy Nhon city and Nha Trang-based Institute of Oceanography jointly installed nets to prevent sharks from coming onshore and attacking humans.
A large number of sharks have appeared off Quy Nhon beach since last year.
In the first two weeks of September, 2011, Nguyen Van Luyen, a local fishmermen caught 6 sharks near Hon Dat Island within two nautical miles of shore.
In July, 2011, scientists from the Nha Trang-based Institute of Oceanography captured two sharks as part of a study on the attacks.
On June 12, 2011, Phan Van Giau, a fisherman, caught a shark weighing nearly 50 kilogram within 100 meters of shore. Just one day after, another fisherman captured a juvenile white shark measuring 1.5 meters in length and weighing around 60 kilograms at the same area.
