Stardew Valley 1.6 Fish Pond Expected-Value Optimizer

Fish Pond Expected-Value Optimizer

This calculator uses Stardew Valley 1.6.15.24356 fish pond rules rules. It does not use fixed “roe per day” constants.

Model: daily container chance = lerp(BaseMinProduceChance, BaseMaxProduceChance, population ÷ 10). Eligible output rows are tested in file order; the first successful row wins. Roe then receives the game’s repeated 20% extra-stack roll.

Fish Population: 10 Process Roe in Preserves Jars Artisan on processed Roe Golden Animal Cracker already accepted

Pricing rules used

Raw Roe: 30g + floor(base fish price ÷ 2).
Aged Roe: 2 × raw Roe price + 100g.
Sturgeon Roe becomes Caviar at 500g base.
Artisan multiplies processed value by 1.4; it does not boost raw Roe.
Special-item sale value is excluded from the displayed Roe gold/day because many outputs are better used than sold.

Golden Animal Cracker

In 1.6, an eligible populated Fish Pond can accept one Golden Animal Cracker. The pond stores a persistent goldenAnimalCracker flag and doubles future output stacks whenever an item is produced. It is not a one-day boost; an empty, ineligible or already-enhanced pond can reject the item.

Included fish: Lava Eel, Sturgeon, Blobfish, Blue Discus, Stingray and Lionfish. Population input assumes you have completed the necessary capacity quests.
