Fishing rod - check. Smells of the sea - check. He's a fisherman alright.

Jones takes you to hunt the beast during the Deadliest Catch quest. After completing the quest you can go hunt the beast another ten times by speaking to Jones or selecting his right click "Go-hunting" option. Hunting the beast gives a substantial amount of hunting experience as well as some other loot. For more information on hunting the beast after the quest please refer to the bottom of the Deadliest Catch quest guide. After completing the quest Jones will also supply you with Big cast net's and Small cast net's for free (You need to talk to him to get them).
