In the world of Fisch (Roblox), determining the fair trade value of your catch is essential for maximizing your profits and ensuring you don't get scammed during player-to-player trades or when selling to the merchant. Unlike standard items, fish value is dynamic, relying heavily on weight, mutations, and appraisal quality.
How is Fisch Value Calculated?
The "Fisch Trading Calculator" uses a formula derived from game mechanics to estimate the C$ value. Here are the core factors:
Base Species Value: Every fish, from a simple Trout to a Great White Shark, has a starting base price in C$.
Weight (kg): Heavier fish are exponentially more valuable. A fish that is 50% heavier than average can be worth double the price.
Rarity & Mutation: Special attributes like Shiny, Sparkling, or Atlantean apply massive multipliers to the final value.
Appraisal Quality: The star rating of your fish acts as a final quality multiplier. A 5-star "Godly" catch is significantly more valuable than a 1-star catch of the same weight.
Common Trading Multipliers
When negotiating a trade, keep these standard multipliers in mind:
Shiny: typically adds 1.5x to 2.0x value depending on demand.
Mythic Tier: Base value is usually 4x higher than common fish.
Events: During seasonal events, specific fish may have a temporary 1.5x merchant bonus, increasing their trade desirability.
How to Use This Calculator
Identify Base Value: Check the bestiary or wiki for the base C$ price of the fish species you caught.
Input Weight: Enter the exact weight in kilograms (kg) as shown in your inventory.
Select Modifiers: Choose the correct rarity tier, mutation type (if any), and appraisal star rating.
Check Market Bonus: If there is currently a merchant multiplier active (e.g., x1.2 sell value), input that to see the boosted price.
Calculate: Click the button to see the estimated fair trade value in C$.
Note: This tool provides an estimate based on mathematical multipliers. True player-market value (RAP) may vary based on the specific demand for certain rare mutations (like Atlantean).
