In one of the most recent updates in Fisch, a new location called Treasure Island was added in the Second Sea. You can reach this area by riding an orange Whale that spawns in the Isle of New Beginnings. Once you are in Treasure Island, your main goal becomes to complete its bestiary by catching every fish in its pool. By doing so, you can earn yourself a decent amount of XP and Embercoins (E$).
Every fish in Treasure Island prefers a specific bait that you can use to lure them out of the pool. This article highlights the favorite bait of every fish in Treasure Island. You can use them to increase your chances of catching the fish and completing the Treasure Island Bestiary in Fisch.
How to catch all Treasure Island fish in Fisch (100% bestiary)
In this Roblox title, you can reach Treasure Island by riding an orange Whale. The Whale spawns in the Isle of New Beginnings only during the rainy season. A general thing to remember is that this huge creature won't necessarily spawn during rain. This weather just increases the spawn chances of this large fish.

You can find the orange Whale on the southwestern side of the Isle of New Beginnings. To be precise, you can find it on Fisch's GPS coordinates XYZ: -30, -1350, -2160. After it spawns, the Whale will dock in this spot for eight minutes. Within this period, you can enter the Whale's interior and wait for its departure. Once it departs, it will take five minutes for you to reach Treasure Island.
Once there, you can use the following baits to catch all 21 fishes and complete the bestiary.
