How to Fish Mods Hub: Loaders, Tools, and Compatibility
How to Fish mods hub: a roughly 70-mod PC scene on BepInEx and MelonLoader — bigger lobbies, keep-inventory, weather, and cheat tools for patch 1.0.9.

Modding in How to Fish is a PC-only affair with a fast-growing scene: roughly 70 mods and tools hosted across Thunderstore and Nexus Mods, almost all of them loading through BepInEx or MelonLoader. Because the game patches quickly — five updates in its first six days — version compatibility is the one rule that matters more than any mod pick.
The guides
The mods guide covers the loader setup, the best picks (More Players, Keep Inventory, Always Win Roulette, the seagull mods, World Item Spawn), and host-only rules for multiplayer sessions. If you came here to raise your lobby size, note the vanilla game already supports 8 players since Patch 1.0.4 — the max players guide explains the ceiling before you mod past it.
