The Outer Deep bestiary in Fisch holds 21 entries in total, split between 19 fish and items and two crates. Each fish has its own combination of bait, weather, time of day, and season, so finishing the collection is less about luck and more about lining up the right conditions before you cast. Below are the exact requirements for every entry, plus the fastest way to work through them.
Quick answer: Catch the two crates and the Broken Flashlight first with Magnet bait (no conditions needed), then group the remaining fish by matching season, weather, and time so you can clear several entries in one setting before changing the environment again.
How to reach the Outer Deep fishing spots
Start at the main marker in the Deep and leave the temple. Swim to the right and look for a small pocket of land on the right-hand side. That land marks the Outer Deep fishing area where every bestiary entry can be caught.
All 19 Outer Deep fish and item requirements
Some entries can be caught with either a rod or a harpoon, while others are rod-only. Match the bait to the fish and use totems if you need to force a specific weather or time before casting.
| Entry | Bait | Weather / Time / Season | Tool |
|---|---|---|---|
| Broken Flashlight | Magnet | Any / Any / Any | Rod or harpoon |
| Mantis Shrimp | Chitin Pellets | Rain / Day / Spring or Summer | Rod or harpoon |
| Pistol Shrimp | Shrimp | Foggy / Night / Summer or Autumn | Rod |
| Sacabambaspis | Worm | Clear / Day / Spring | Rod |
| Abadah Chromis | Fish Head | Foggy / Night / Summer | Rod |

The two Outer Deep crates
Two of the 21 entries are crates rather than fish. The Aquatic Tackle Box and the Deep Tackle Box both count toward completion, and neither one needs a specific weather, time, or season. Equip Magnet bait and fish them up whenever you like.
| Crate | Bait | Conditions |
|---|---|---|
| Aquatic Tackle Box | Magnet | None |
| Deep Tackle Box | Magnet | None |
Fastest order to clear the bestiary
Tip: A few conditions overlap neatly. Trench Grubs cover both the Mero Goby and the Papillated Redbait, Crustacean Mix covers the Formosa Seabass and the Nkosi Pygmy Pipehorse, and Luminous Flakes covers the Japanese Linebelly Swallower and the Pacific Hatchetfish. Bring extra of those baits to double up.
How to confirm the bestiary is complete
The Outer Deep bestiary reads as finished once all 21 entries are logged, the 19 fish and items plus the two crates. If an entry still shows as missing, check the exact bait first, then the weather, time, and season, since a single mismatched condition is the most common reason a fish will not bite. Force the missing condition with a totem and cast again with the correct bait to fill the last slot.
