Darkclaw Lobster can only be fished in the open sea of a couple different zones. Its primary use is to help you in the line of cooking. Lobsters can’t be fished in schools; as such, I’ll only provide the coordinates of where I fished, instead of giving the full map. You can fish this lobster up anywhere along the shoreline of the given zones, however. ★ Profession Required: Fishing ★ B...[Read More]
Giant Mantis Shrimp can be fished from Giant Mantis Shrimp Swarm. It’s primarily used in cooking, especially with the Way of the Steamer, which increases versatility.

Raw Loch Frenzy can only be found in open water within the alliance zone of Loch Modan. As such, there's really only one lake to fish in, just watch out for the Modan Monster. He can be a challenge for low levels.
Mithril Bound Trunk is primarily going to be found in Floating Wreckages, though they can also be found in a Stonescale Eel Swarm. You can't sell the trunks specifically, but you can sell what's inside of them.
Iron Bound Trunk is a chest that you can fish up from Waterlogged Wreckages, but also some other schools that cater more toward specific fish. You can't sell the trunks specifically, but you can sell the contents inside them.
Firefin Snapper is a bit odd in the fact that it doesn't actually help you out in cooking, but in alchemy instead. They can also be found not only in the schools dedicated to them, but also the mixed ocean school as well.
Stonescale Eels are used for making an Alchemy reagent. Certainly not as useful as the fish you may be looking for now, but they still have their place.
