Frequently Asked Questions
How is fish value calculated?
We take the base price of the fish and multiply it by the modifiers you select: Stars, Mutation, and
optional Weight.
Formula: Base × Stars × Mutation × Weight.
How does the Dive Survival Calculator work?
It calculates your total oxygen (Tube HP) and subtracts drain from travel time and catching fish. Catch drain depends on your Gun DPS and the fish's rarity/toughness, outputting if your mission is safe, risky, or unsurvivable.
Is this tool official?
No — this is a fan-made community tool. We are not affiliated with the developers of Abyss.
Does it work on mobile?
Yes! The entire site is responsive and designed to work on phones and tablets.
What data does the Race Reroll Calculator use?
It draws from community-verified reroll probabilities and passive effects. Enter your target, and it estimates rerolls needed so you can judge whether it’s worth the cost.
Can I calculate values for mutated fish?
Yes. The Fish Value Calculator includes mutation options to show potential earnings with different multipliers.
What if the game updates change mechanics?
We track changes and adjust calculators when mechanics shift. If something looks off, use the Feedback button to report it.
