In the fishing guild you will find a wide range of RS Gold tools that are useful during training. There are free spawns equipped with nets, rods and cages and harpoons as with a cooking space that allows those to cook their food. Within the guild, you will also find a fish store that stocks feathers and bait. 

You can sell your cooked and uncooked fish to Roachey who manages the Fishing Guild shop. Due to the distance between the fishing spots and the bank, this location is ideal for people who wish to learn about Sharks, Lobsters, Tunas and Swordfish.

In the northern platform, there is also an Nylie Minnow NPC. If you're wearing a full Angler attire, have at minimum 82 fishing hours and have completed Fishing Contest quest, she'll transport you to Minnow landing platform. There, you will be able to catch Minnow from one of four spots. These will later be exchanged for Raw Sharks in 40:1 ratio.
