Auto Fisher Pro

Auto Fisher Pro is a client-side fishing mod for Minecraft 1.21.1 on Fabric. It casts your rod, waits for a bite, reels in and casts again. It also handles what usually ends a long session: a rod about to break, a full inventory, hunger, junk filling your hotbar, and danger nearby.

Version 2.0 is a full rework of the original mod. It runs only on your own client, so nothing needs to be installed on a server.

Features

• Automatic fishing loop. Casts, detects the bite, reels in and recasts. The pause between casts is randomised, so no two cycles have the same timing.
• Bite detection from the server's signal. The mod reads the same bite packet your client already receives, so it never reels in on a false bite. An optional fallback also watches the bobber's movement.
• Safety stops. Fishing stops and a chat message tells you why when you take damage, your health gets low, a hostile mob comes close, your inventory is full, you die, you disconnect, or nothing has bitten for a long time. You can also pause during thunderstorms and at night.
• Rod management. When the current rod runs low, the mod switches to the best usable one. A rod with Mending stays in use longer, since fishing XP repairs it.
• Loot rules. Keep or throw away items by name, tag or enchantment. Enchanted books, Name Tags and enchanted gear are protected by default, and a keep rule always beats a drop rule.
• Auto-eat. Eats from your food list when hunger drops to the level you set, and only between casts.
• On-screen status. An overlay shows the current state, catches split into fish, treasure and junk, catches per hour, session time and rod durability.
• Profiles. Save a whole setup under a name like "Treasure" or "XP" and switch with one key. Profiles export and import as files.
• Spot check. Warns you once if the bobber landed where treasure cannot spawn.
• Settings screen with tabs for General, Timing, Safety, Inventory, Loot Rules, HUD and Profiles.

Quick start

1. Stand next to open water and hold a fishing rod. Wide, deep water is best, because treasure only spawns in open water.
2. Press K to start and K again to stop.
3. Press O to open the settings.

The mod is always off when you launch the game or join a world, so it never starts fishing on its own.

Default keys

• K: start or stop fishing
• J: emergency stop
• O: open settings
• Reset session stats and next profile: not set by default

You can rebind every key in Options, Controls, under "Auto Fisher".

Requirements

• Minecraft 1.21.1
• Fabric Loader 0.15.0 or newer
• Fabric API
• Cloth Config API (required, it provides the settings screen)
• Mod Menu (optional, it only adds a Config button to the mod list)

Updating from 1.0

Your old settings are upgraded automatically, and a backup of the old file is kept next to it.

Multiplayer

Auto Fisher only performs actions a player can perform, but many servers forbid automation and some detect it. Read a server's rules before you use the mod there. You are responsible for following them.

Known limits

• The spot check estimates the game's open water rule and can be wrong in unusual builds.
• The mod does not walk, and it does not move items into chests.
• It targets Minecraft 1.21.1 only.

Auto Fisher Pro is a premium-quality, client-side automation mod for Fabric 1.21.1 designed for players who want a "set it and forget it" fishing experience without the risk of predictable, robotic patterns.

Whether you are playing on a private server or just want to farm treasure efficiently in single-player, this mod handles everything from bite detection to inventory management.

✨ Key Features

• 🛡️ Anti-Ban Design (Human-like Delays): Unlike basic auto-fishers that click instantly and get you flagged, this mod uses fully configurable, randomized tick delays between casting and reeling. No two fishing cycles are exactly the same, making your actions look entirely natural to server logs.
• 🎯 3-Layer Bite Detection: Combines the server's caughtFish flag, a Y-level baseline drop sensor, and a velocity spike check. You will catch virtually every fish on the exact tick of the bite.
• 🔄 Auto-Switch Rods: Never break an enchanted rod again. When your current rod drops to 5 durability or lower, the mod automatically scans your inventory and swaps a fresh rod into your hand.
• ♻️ Smart Junk Filter: Keep your inventory clean. The mod periodically scans for configured "trash" items (like rotten flesh, lily pads, or leather boots) and automatically throws them away so you only keep the good loot.
• ⚙️ In-Game Config GUI: Access all settings, sliders, and junk item lists instantly via the ModMenu screen. No need to mess around with text files!

🧩 Required Dependencies

To use this mod, ensure you have the following installed in your mods folder:

• Fabric API
• Cloth Config API
• ModMenu

🚀 Quick Start Guide

1. Install the mod and its dependencies.
2. Join a world, hold a fishing rod, and stand near the water.
3. Press Escape → Mods → Auto Fisher Pro → Config.
4. Toggle Enable Auto Fisher → ON and adjust your delay sliders if desired.
5. Click Done and let the mod do the work!

(Note: While this mod is designed to mimic legitimate client-side interactions, use it on public multiplayer servers at your own risk. Always respect server rules.)
