Every fish in the game has a minimum and maximum size in the game's code. The size of the largest fish you've caught shows up in your Collections tab.

What determines the size? The same factors that determine the quality: what distance the bobber is from land, how large the body of water you're fishing in is, whether the fishing minigame was done perfectly, etc. However, unlike the quality, the size is completely aesthetic and has no bearing on sell price. Even so, you may find yourself frustrated at the hours upon hours you've spent trying to catch the largest possible octopus for completion's sake, or rage at the fact that catching the largest possible goby cannot happen in the game given the small body of water it comes from.
The minimum and maximum sizes are determined in a document called [Fish.xnb] in the game files. This mod replaces that file with a new one where the maximum size is the only size you can catch, allowing you to complete your ultimately meaningless Big Fish Collection with ease.

fishyyy

Fish.xnb
This file is an edit of the vanilla file by the same name, located here:steamapps/common/Stardew Valley/Content/Data
If you want to install this mod without Content Patcher, you can delete the original Fish.xnb file, and then drag the modded Fish.xnb file from the [CP] Big Fish/fishyyy folder into the Data folder. THIS WILL REPLACE THE ORIGINAL Fish.xnb FILE IN THERE. IF YOU WANT TO UNINSTALL THE MOD, YOU WILL HAVE TO TAKE OUT THE MODDED Fish.xnb FILE AND PUT THE ORIGINAL Fish.xnb FILE BACK IN ITS PLACE. SAVE A BACKUP OF THE ORIGINAL Fish.xnb FILE IF YOU WANT TO EVER BE ABLE TO UNINSTALL THE MOD.6. Enjoy bigger fish.
Warnings:
THIS MOD MAY INTERFERE WITH FISHING OVERHAUL MODS THAT MAKE THE SIZES ACTUALLY MATTER, OR MODS THAT ADD NEW FISH. USE WITH CAUTION.
ANY CHANGES THIS MOD MAKES TO THE SIZES OF FISH IN YOUR COLLECTION TAB ARE PERMANENT. IF YOU CATCH A 60 INCH SALMON AND UNINSTALL THE MOD, THAT SALMON WILL STILL BE 60 INCHES. THE 60 INCH SALMON IS NOW A PART OF YOUR SAVE FILE. YOU CANNOT RID YOURSELF OF IT.
This mod does not change the quality or sell price of the fish you catch. You will still have to use vanilla methods or other mods to catch gold and iridium quality fish.
As of uploading, this mod is 1.6 compatible. If later versions come out where new fish are added, it may break those fish in the game. I can't guarantee I will consistently update this mod as I have the commitment of a peanut, and this is the first functioning mod I've ever made.
