Formula-audited for Stardew Valley 1.6.15

Stardew Valley Fish Pond calculator

Calculate Roe, Aged Roe, Caviar and Artisan values, then compare every valid Fish Pond occupant. Priority ponds also show verified special outputs, ordered-roll probabilities, spawning time, and the next capacity quest.

Population simulator

Fish Pond output and Roe value

Model the daily output check, ordered item-selection rules, reproduction interval, and next population quest for every vanilla pond-eligible object. Unknown or modded species never receive guessed drops.

Population planning

New fish normally spawn every 4 days when capacity is available.

No later verified capacity quest for this population.

Goal-based comparison

Choose a pond for what you need

Compare verified pond outputs at population 10. Each fish is capped at its own maximum population, and Legendary Fish remain capped at one.

Ranks conservative expected daily value from verified pond outputs. Unknown-value rewards are listed but never assigned invented gold.

Probability note: these are model-based expectations, not guaranteed daily drops or fixed daily income. Preserved Roe rankings use minimum Roe quantities and intentionally exclude the repeated 20% bonus-Roe roll. Rare rewards exclude common debris and are ranked by verified output probability, not by an invented gold value. Low-maintenance ranks setup effort only.

How to read this: the base roll is not fixed daily gold. Structured rows show the final per-day item probability; Roe quantities are minimums before the repeated 20% extra-Roe roll. Golden Animal Crackers double output quantity, not chance.

Roe formula

Roe value = floor(30 + fish base price / 2). This uses the fish base sell price, not fish quality.

Aged Roe

Most Roe becomes Aged Roe in a Preserves Jar at 2x Roe value, then Artisan can apply to the finished artisan good.

Sturgeon exception

Sturgeon Roe becomes Caviar worth 500g instead of normal Aged Roe. That exception is audited in the build checks.

The eligibility list follows Stardew Valley 1.6.15: rod and Crab Pot fish are accepted, as are Coral and Sea Urchin. Algae, Seaweed, and the three Jellies are not valid pond occupants. Squid, Midnight Squid, and Coral do not use the normal Roe-preserving path, so the calculator shows their preserved Roe value as not applicable.
