I'm primarily playing Stardew Valley on iOS, currently at version 1.4.5.145.

I've also installed SV on macOS (version 1.4.5), but I only play that version occasionally to test obscure game details. Its real value to me is access to the game data files, etc., since I like to dissect game mechanics.

Fish Size and Quality

The following table provides the predicted fish size and quality, based on Fishing Zone and player Fishing level. There's a random component to the calculation, meaning there's a range of possible sizes.

Fishing Zone	Fishing Level	fFishSize		Fish Quality (% chance)			Perfect Fish Size (inches)

Definitions:

• Fishing Zone: also known as clearWaterDistance, or tiles from nearest land.
• S/G: gold-quality fish if cast is perfect; silver-quality fish otherwise
• G/I: iridium-quality fish if cast is perfect; gold-quality fish otherwise
• fFishSize: the fractional fish size (range 0 to 1), which is the primary output of the game code equations. fFishSize directly determines the fish quality, but is only one factor in the final fish size.
  • Actual fish size (for a perfect fish) will be:

    Size = fFishSize * (maxFishSize-minFishSize) + minFishSize + 1

Where maxFishSize and minFishSize are the raw values from the game data files.

Notes:

• Fishing level includes any buffs
  • (In version 1.3, buffs past level 10 were ignored by this calculation).
• The size ranges shown are only valid for perfect casts. Sizes will generally be smaller on non-perfect casts.
• Fishing Zone=4 has been excluded because it does not happen
