I wrote an article on the Tuna wranglers in Australia at http://www.cricketlegs.com/2007/08/31/the-tuna-wranglers/. The discovery channel series shows how these type of fisherman are helping the fishery based on how many they are allowed to keep. Some type of Quota issued by state they say will help the numbers for years to come. Looks like we need more help and smaller quotas.
