Fisch Calculator
Price your catch by weight, and understand what a calculator can and cannot tell you.
To price a Fisch catch, multiply its weight in kilograms by that species' C$/kg value, then by any mutation multiplier on the fish. An Arapaima is 1.76 C$/kg, so a 150 kg one sells for about 264 C$, or 660 C$ with a 2.5x mutation. Pick your species below and enter the weight to calculate it. Species prices are Official Fisch Wiki data synced September 15, 2026; you enter the mutation multiplier from your own catch.
What this calculator can and cannot tell you. The species C$/kg table above comes from Official Fisch Wiki data re-synced daily (last sync September 15, 2026), so the weight × value half of this maths is dated rather than silently stale. The multiplier is a different story — it depends on the mutation and attributes your own catch rolled, so it stays an input you supply. This explanation was last reviewed September 14, 2026. And no off-site tool can compute C$/hr for you, because that depends on encounter rate: your rod luck, bait group and totem uptime. The merchant quote in your inventory is always the authoritative price.

How it works
The core formula
Sell price = (weight in kg) × (species C$/kg) × (the fish’s one mutation multiplier) × (attribute multipliers). Worked example: an Arapaima is 1.76 C$/kg in the Official Fisch Wiki data synced September 15, 2026, so a 150 kg one sells for about 150 × 1.76 = 264 C$ — in line with the 264 C$ average the wiki lists. Add a 2.5× mutation and the same fish is about 660 C$. A fish carries at most one mutation (Official Fisch Wiki, Mutations page, guide text reviewed September 14, 2026); attributes such as Shiny and Sparkling (1.85× each) multiply on top of it.
C$/hr is an encounter problem, not a math problem
Raw sell-price math is easy — the hard variable is encounter rate. How often you pull a Rare vs Common at a given rod/bait/biome depends on your Luck stat, the bait group, and weather/totem windows. No off-site calculator can know your current rod enchants or totem uptime, so we don’t pretend one can.
What a calculator can’t fix
Even a perfect-on-launch calculator breaks when Fisch rebalances C$/kg for a popular species or swaps a mutation multiplier. Treat any number you see in a third-party Fisch calculator as stale-by-default; cross-check the species price against the Official Fisch Wiki before making grind decisions.
Frequently asked
How do mutations affect sell price in Fisch?
A fish can carry only one mutation at a time, so mutations never stack with each other. Per the Official Fisch Wiki (Fish and Mutations pages, guide text reviewed September 14, 2026), price per kg × weight is rounded up to a base price, then multiplied by that one mutation and by any attributes — Shiny and Sparkling (1.85× each), stacking with the mutation (multipliers from the data synced September 15, 2026) — and rounded up again. Size tags like Big or Giant are not multipliers.
How do I calculate C$/hr in Fisch?
Time a 15–30 minute session at your current biome + rod + bait + enchant setup, record total C$ earned, then scale to an hour. That’s the only reliable number — every theoretical "expected C$/hr" ignores your real encounter rolls.
What does Luck actually change?
Luck biases the rarity roll toward rarer species within the bait’s target group. It does not make a Common species worth more C$/kg, and it doesn’t open species that are gated by weather, time, or totem.
