Fisch Value Calculator

How to Use the Fisch Value Calculator

Three fields and all three matter. Pick the fish, type in the exact weight from the item, then set the mutation and the attribute if it has them. Leave the weight alone and the tool assumes the species average, which is a real number but almost certainly not your fish, because the whole point of this game is that no two catches weigh the same.

What comes back is the Merchant C$ sell price, built from the game's own formula rather than looked up in a table, so it works for combinations nobody has ever published. That distinction matters more here than in any other game on this site: this figure is not an estimate of what a fish is worth, it is what the merchant will actually pay you. Cross-check the species against the Fisch value list if a number looks surprising.

How Weight Changes a Fish's Value

Linearly, which is worth stating because several games do it differently. Each species has a fixed C$/kg rate, so the calculation is simply that rate times the actual weight on the item, rounded up to a whole C$. Double the weight and you double the money. There is no squaring here.

The consequence is that total value and efficiency are separate questions, and the list will mislead you if you only ask the first. Great White Shark sells at 5,000 C$ for 1,000 kg, which is 5 C$ per kg. Megalodon is worth far more per catch at 28,285 C$ but weighs 58,500 kg, working out at 0.48 C$ per kg. A Goldfish at 42 C$ and half a kilo runs near 93 C$ per kg. If you are choosing what to fish for rather than what to sell, the rate is the number to compare, and the Fisch trade checker is the place to weigh two catches against each other rather than one against the merchant.

Mutations and Attributes in the Calculator

Both are here and both are multiplicative, applied after weight. The mutation dropdown carries 35 options, from Aether at 12x down through Tryhard and Fabulous to the Appraiser's own set ending at Midas 2.5x, and a fish carries at most one of them. The attribute control is separate because a fish can hold more than one attribute at a time.

Shiny and Sparkling are 1.85x each and they stack multiplicatively rather than additively, so the pair is 3.4225x and not 2.7x. Rather than leave that to a stacking rule that would get it wrong, the four real states are offered directly: none, Shiny, Sparkling, or both. What you will not find is a Big or Giant toggle, and its absence is deliberate. Those words describe weight above the base maximum, and weight is already in the calculation, so a calculator that multiplies for Giant on top of a weight box is billing you twice for the same kilogram.

Why Fisch Calculators Disagree

Double counting is the first and largest cause, and it is almost always Big or Giant being treated as a multiplier. A tool doing that will read high by two to two and a half times on exactly the catches you care most about, and it will look confident while doing it.

Second is attribute stacking. Adding Shiny and Sparkling instead of multiplying them gives 2.7x where the game gives 3.4225x, a quiet 27% shortfall that only shows on the rarest fish. Third is rounding: the real formula rounds up twice, once after the weight step and once at the end, which moves small catches by a C$ or two. Beyond that, each species has a fixed rate and those rates are stable, because they come from the game rather than from anybody's opinion. Heavier fish sell for more, verified formulas produce the same answer everywhere, and that is why Fisch calculators agree far more often than value lists for trading games ever do.
