In Fisch, the Open Ocean is a vast portion of the sea where you can catch fish. This spot is located in the Second Sea, which you can reach after beating the Cthulu boss. You can catch unique fish like the secret Psychedelic Frogfish and Sea Leviathan here. Similarly, there are 21 other fish you can catch to complete the Open Ocean bestiary.
Completing the bestiary is very rewarding as you get a generous amount of XP and Embercoins - a currency exclusive to the Second Sea. To help you acquire both of these currencies, we have given the ideal weather, time, date, and bait to catch all fish in the Open Ocean.
How to catch all Open Ocean fish in Fisch (100% bestiary)

The Open Ocean is located in the Second Sea, and you can reach it only after defeating the Cthulu boss. You can find this boss by heading over to the western side of Terrapin. Here, you can talk to an NPC called the Sea Traveler, who is standing in front of a cave wall. You must get past this wall to enter the Crypt of the Green One, where the Cthulu boss spawns.

In the Crypt of the Green One, you will find a passage locked behind a big iron gate. To open this gate, you must speak with the NPC standing in front of it. You can then go to the other side of the passage to access the Cthulu boss chamber. Note that you must be on level 200 or more to cross the passage. If you are below the specified level, the NPCs standing there will burn you down.
To defeat Cthulu, you must use the Keeper's Torch found in the boss chamber. Once you have done that, the Second Sea will be permanently unlocked. Like Moosewood, Waveborne is the starter island in the Second Sea. From here, you must get past every island to reach the Open Ocean.
Upon reaching the Open Ocean, you can use the following table to catch every fish.
Upon catching all 23 fish in this area, you will complete the Open Ocean Bestiary. Doing so will reward you with 2000 XP, 2000 E$, and a badge called "Bestiary; Sea 2 Open Ocean."
