Tuna Wranglers (2007) is a documentary film produced by the makers of Deadliest Catch. It follows the exploits of the southern bluefin tuna industry in South Australia as it captures wild fish and transports them to grow-out pens where the fish are fattened up for sale to the Japanese market. It features footage of fishermen diving into tuna pens to wrestle sharks in order to protect their multimillion-dollar stock. The film was directed and produced by Mark Strickson for television and has also been released on DVD in several regions. Critics of the film noted the omission of the southern bluefin tuna's conservation status and the incongruous casting of an American narrator given the exclusively Australian cast and story. The film was produced by NHNZ for the Discovery Channel. A year aft
