Rarity database

Deep Fishing Fish Rarity Rankings

The official badge endpoint gives the site a reliable vocabulary. It does not give us permission to invent every fish name or percentage.

No story spoilers

§How to use the list in a session#

  • Push Strength so the cast reaches the water you intend to fish.
  • Keep the first catch for a named badge or mutation goal.
  • Sell ordinary volume to fund the next distance test.
  • Treat luck as an optional live-shop decision after distance.

§Missing data remains visible#

No official fish catalog, exact per-water table, drop percentage, mutation percentage, or sell-value index was available in the checked endpoints. A future verified export can extend this page without rewriting the badge facts.

§Exotic rarity: a dated official addition#

The September 6 official announcement adds Exotic rarity, five new Exotic fish to World 1 and four to World 2. It also names a Secret / Exotic hatch minigame and pull cutscene. These are historical update counts, with current species, exact odds and a complete rarity ordering still unverified.

When checking a catch, read its rarity label separately from its mutation. The reroll announcement discusses changing a caught fish mutation; it does not document upgrading rarity through a scroll.

§FAQ#

Is Common an official badge rank?

The checked official badge list confirms the named first-catch ranks, while Common is the community term for ordinary bulk catches. Keep that distinction visible.

What is the highest named rarity?

Secret is the highest named rarity exposed by the checked First Secret badge. That does not reveal every species or rate.

Does a mutation increase rarity?

The separate First Mutation badge supports treating mutation as its own track. A promotion rule was not published by the checked official sources.
