The fastest way to get Bone Shard and Ancient Bone together in Fisch is to farm shark-type fish in Gloomy Crevice, with the Pacific Sleeper Shark as your main target and the Lower Deep’s Atlantic Dragonfish only as a Bone Shard backup.
Bone Shard and Ancient Bone are late-game crafting materials, and the quickest way to stock both is to fish the deep, dark Gloomy Crevice for shark-type catches. Sharks there roll both materials as bonus drops, so a single loop feeds both counters at once. The Lower Deep is worth a detour only when you specifically need Bone Shard and can’t get sharks to bite.
Fastest route and the Bone Shard backup
| Material goal | Best farm |
|---|---|
| Bone Shard + Ancient Bone | Gloomy Crevice sharks (Pacific Sleeper Shark) |
| Bone Shard only (backup) | Lower Deep Atlantic Dragonfish |
Key Everything comes down to one choice: are you after both materials, or just Bone Shard? If you need Bone Shard and Ancient Bone, the Gloomy Crevice shark farm is the only route that feeds both at the same time. If you only need Bone Shard — or the sharks are being stubborn — the Lower Deep’s Atlantic Dragonfish is a clean top-up that keeps Bone Shard flowing without touching Ancient Bone.
How to farm sharks in Gloomy Crevice in Fisch
Here’s the full loop for pulling both bone materials out of shark catches in the Gloomy Crevice.
STEP 1/5
Head to Gloomy Crevice
Travel down to the dark, deep Gloomy Crevice zone, where the shark-type fish spawn.
STEP 2/5
Check the Bestiary for your shark
Open the Bestiary to read each shark’s preferred bait, weather, cycle and season before you cast.
STEP 3/5
Target shark-type fish only
Ignore random fish and cast only at the large shark silhouettes — non-sharks don’t roll the bone materials.
STEP 4/5
Reel in sharks for the drops
Land each shark to trigger the Extra Find reward, which is where Bone Shard and Ancient Bone actually come from.
STEP 5/5
Repeat the loop until you have enough
Keep circling the zone and catching sharks until your Bone Shard and Ancient Bone counts reach what you need.
Aim for perfect catches and equip your strongest rod or a harpoon gun — faster, cleaner shark catches mean more Extra Find rolls per hour, and that roll count is the entire farm.

How shark catches drop these bone materials
Sharks don’t hand over bone materials as their main catch — they roll them as an Extra Find, the bonus reward that pops up alongside the fish itself. Both the Pacific Sleeper Shark and the Bluntnose Sixgill Shark trigger Bone Shard Extra Finds, and those same shark catches are also your best line on Ancient Bone.
Key That’s why the loop is so efficient: every clean shark catch is another roll on both materials at once. Community testing points to roughly a coin-flip Bone Shard chance per shark, though exact rates aren’t fixed — treat this as a repeat-farm route rather than a guaranteed drop, and let the numbers climb over a steady grind.
When to swap to Lower Deep Atlantic Dragonfish
If the Gloomy Crevice sharks won’t cooperate, drop down to the Lower Deep and target the Atlantic Dragonfish instead. It’s a reliable Bone Shard source, so it keeps that counter moving when shark spawns dry up. Just don’t lean on it for Ancient Bone — the Dragonfish won’t drop it, so it’s a top-up route for Bone Shard, not a replacement for the shark farm.
Routes and mix-ups to avoid
A few habits quietly waste your time here. Don’t stop for random fish while you farm — non-shark catches don’t roll the bone materials, so every cast that isn’t aimed at a shark is dead time. Skip any route that points you to Tidefall or other limited-time events for these drops; that content is closed and no longer accessible in-game. And don’t confuse Bone Shard with the game’s Rift shards — Shard of Embers, Shard of Nebulas, Shard of Tides and Shard of Roots come from the Sunstone rift parkours and have nothing to do with the shark farm.

Frequently Asked Questions
Can Atlantic Dragonfish drop Ancient Bone too?
No. The Atlantic Dragonfish in the Lower Deep only yields Bone Shard. Ancient Bone comes from shark catches in the Gloomy Crevice, and there’s no known shortcut around it — if Ancient Bone is what you’re short on, head back to the sharks.
What bait should I use for Pacific Sleeper Shark?
Squid is the Pacific Sleeper Shark’s preferred bait. It also favors Foggy weather, the Night cycle and the Summer season, so lining those conditions up makes it bite far more often.
Is Bone Shard the same thing as the Rift shards?
No. Bone Shard is a crafting material you pull from sharks. The Rift shards — Embers, Nebulas, Tides and Roots — are separate rewards from the Sunstone rift parkour obbies and aren’t part of this farm at all.
