Fisch Bestiary Guide: Completion Rewards & Tips

What Is the Fisch Bestiary?

The Fisch bestiary is your in-game logbook — a living record of every fish and item you've personally caught across the game's many islands. If you're serious about progression in Roblox's most popular fishing simulation, the bestiary isn't optional reading: it gates some of the most coveted rewards in the game, from the Destiny Rod to the shiny Aurora Bobber.

Think of it as a Pokédex for anglers. Every species you hook gets cataloged, complete with its preferred bait, weather conditions, time of day, and season. Every species you haven't caught appears as a dark silhouette with a cryptic Bestiary Hint instead of a description — a breadcrumb trail designed to send you hunting across the map.

Fish are organized by location and sublocation in a sidebar, sorted by rarity from Common upward, with separate tabs for Permanent and Limited catches. Each entry also tracks your discovery dates for normal, Shiny, and Sparkling variants, plus your largest-ever catch of that species in kilograms.

How Bestiary Completion Actually Works

Here's where many players get tripped up: not every fish counts toward completion. According to community wiki documentation, Secret, Apex, Divine Secret, and Limited fish are excluded from your total completion percentage. That means chasing event-exclusive catches won't move the needle on your bookmark color — and trading for a fish doesn't count either.

A few additional rules worth memorizing:

• You must catch everything yourself. A traded fish sits in your inventory but never registers in your bestiary.
• Non-fish loot doesn't count. Magic Threads, Ancient Threads, Lunar Threads, Treasure Maps, and Nukes are fun pulls, but they contribute zero completion percentage.
• Mutations don't complicate things. Any fish can be caught with a Mutation that boosts sell value and changes its appearance, but the base species entry is what registers.
• Weight matters visually. If a fish's weight shows yellow in your inventory, it's heavier than average for its species — a nice badge of honor tracked alongside your "Largest Caught" record.

Your completion percentage displays under every location page, and hitting 100% in any single location turns that text yellow. Your physical bestiary bookmark also changes color as a status symbol: red below 70%, yellow above 70%, and neon yellow at a perfect 100%. A completion jingle even plays the first time you open a newly finished page.

Rewards: What Completion Gets You

The bestiary pays out at every milestone, not just at the end. Individual page completions typically award coins, XP, and a cosmetic bobber. Here's a summary of the headline rewards:

Two rod unlocks are tied directly to bestiary progress, and both are endgame-tier goals:

1. Destiny Rod — Requires at least 350 fish discovered in your bestiary before Caleia at The Arch will sell it to you for 190,000C$.
2. Ethereal Prism Rod — Requires 100% completion of the Veil of the Forsaken bestiary page before purchase.

Don't overlook the Rod Journal, either. This companion menu tracks every fishing rod you've obtained, sorted alphabetically by location, with limited rods in their own category. Unobtained rods appear as silhouettes with basic location and level requirements. Finishing the Rod Journal at 100% awards the Aurora GlowLantern — and if your bestiary is also complete, the Masterline Rod lands on top.

Full Bestiary Locations List

The bestiary spans dozens of zones across Fisch's world, from beginner-friendly shores to abyssal trenches. Community documentation lists the following location pages:

Every page also breaks down into rarity counts, and the scale is genuinely enormous. Community tallies of the full catalog include:

That's hundreds of entries — but remember, the Limited, Secret, and Divine Secret tiers don't count toward completion, which keeps the grind more achievable than the raw numbers suggest.

Practical Tips for Faster Completion

Based on how the system tracks entries, here's how efficient players structure their hunts:

1. Read the hint, then plan around it. Every silhouette entry reveals a Bestiary Hint, and every caught fish's entry lists its preferred bait, weather, time of day, and season. Build a checklist: if a fish wants Rain, Night, and Summer, don't waste bait fishing for it at noon in Spring.

2. Farm day/night and weather cycles deliberately. Many deep-sea and legendary catches — like the Ancient Depth Serpent in The Depths — only appear under specific conditions (in that case, night, on a Truffle Worm). Rotate between locations during off-condition hours instead of idling.

3. Match your bait to the entry. Examples from community data:

4. Stack magnet bait for trash entries. Items like Basalt (Roslit Volcano) and Bone (Brine Pool) are hooked with Magnet bait. They're quick wins that clear entries fast.

5. Target rod-unlock thresholds first. If your goal is the Destiny Rod, don't obsess over perfecting single pages — spread your catches wide until you hit 350 discovered fish, then push for percentage afterward.

6. Don't trade for fish expecting progress. Collectors can fill display cases through trading (with rare exceptions like the Phantom Megalodon), but your bestiary percentage only moves for catches you land yourself.

One quirky footnote from the community: a mysterious location appears to exist beneath Mushgrove Swamp but registers under The Ocean — likely a bug or an undiscovered area, so don't burn hours chasing a phantom entry there.

Is 100% Completion Worth the Grind?

For most players, yes — but strategically. The real power milestones are the 350-fish mark (Destiny Rod access) and Veil of the Forsaken completion (Ethereal Prism Rod access). Full 100% completion is a prestige goal: the payout of 50,000C$, 100,000 XP, and the Aurora Bobber is respectable, but the real reward is a shiny bookmark and bragging rights in a game that rewards dedication.

The bestiary also doubles as a strategy tool. Since every entry documents ideal bait and conditions, a well-filled log makes every future hunt more efficient — you're essentially building your own fishing cheat sheet as you play. And with Fisch receiving frequent content updates since its 2024 launch, new location pages appear regularly, so treat completion as an ongoing journey rather than a one-time sprint.

FAQ

Does the Fisch bestiary count traded fish toward completion? No. You can receive fish through trading, but only fish you catch yourself register in your bestiary and contribute to your completion percentage.

What reward do I get for 100% bestiary completion? Full completion of the "All" section grants 50,000C$, 100,000 XP, and the Aurora Bobber. If your Rod Journal is also fully completed, you additionally receive the Masterline Rod.

Do Limited and Secret fish count toward my bestiary percentage? No. Limited, Secret, Apex, and Divine Secret fish are excluded from total completion, even though many can still be obtained through trading.

How do I unlock the Destiny Rod? Discover at least 350 fish in your bestiary, then purchase the Destiny Rod from Caleia at The Arch for 190,000C$.
