Can catch in Ahrmo Sea with harpoon.

Caught in the deep sea near Daton Island. Affiliated Node: Daton Island

A Skilled Fisherman Quest Note:
Was the first shark I caught here, and I went 2 for 2 when catching a shark species here. I've been able to catch all 4 sharks with one green harpoon for 'A skilled fisherman' by moving around to another location. The whale shark was easily caught off Randis Island deep sea. My harpoon was at 4/30 uses left when I turned in the sharks to the NPC.
