Fishing is a hobby that adventurer's can specialize in for fun or profit. The primary Fishing Guild is located in Port Windurst and can be joined by talking to the Guildmaster Thubu Parohren (C-8). There are smaller guilds located in Selbina and Al Zahbi.

You will need to speak to Thubu Parohren to advance in rank. She will request a test item. Trade it to he and she will grant you a new rank. You can take the test as soon as you acquire 8 skill points in your current ranking. (i.e. 8, 18, 28, 38, etc.)

Fishing equipment is listed on the Auction House under the category Weapons > Ammo & Misc > Fishing Gear. Fish can be found under the category Food > Fish. There are several NPCs in the Guild that will sell you certain gear or fish for a reasonable price. There are ten Fishing vendors in Vana'diel and they are open from 1:00 to 23:00. Lightningsday is the shop's weekly holiday.

Each guild has a Guildworker's Union Representative that will accept a certain item each day in exchange for "Guild Points". You may use these points to purchase special items and key item abilities. Speak to the Union Representative to sign a contract. You may only have a contract with one guild and signing a different contract will cause you to forfeit any guild points acquired from another guild. Additional points may be granted for high quality versions of the item. There is a limit to how many points you can acquire from a particular item.

The Guildworker's Union Representative for the Fisherman's Guild is:

Fennella, Port Windurst (C-8)
