Formula-audited for Stardew Valley 1.6.15

Stardew Valley Fish Pond calculator

Calculate Roe, Aged Roe, Caviar and Artisan values, then compare fish that produce Roe in Fish Ponds. This tool uses verified item values instead of fake fixed monthly income because pond output rolls vary by population and item 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.
