...do you take the hook out of this? Or do they literally just let it go with the hook stuck in its mouth? 
Can any anglers shed light?

BBC said:Father and son catch 7ft shark from kayak
23 August 2011 Last updated at 14:32 Help A father and son who went fishing in the Gulf of Mexico caught something a lot bigger than they expected.
Kevin Stevens and his nine-year old son, Hunter, spent an hour reeling in a 7ft (2m) long black tip shark from their 12ft (3.5m) kayak.
After getting some good pictures the pair agreed it was time to cut the shark loose.
