Auto-Fish
Auto-Fish is a client-side Fabric utility that takes over the casting, bite detection and reeling of the fishing rod while the player holds it.
What it does
Once a fishing rod is held in the main hand and the player stands at the edge of water, pressing O toggles the helper on, and the action bar shows that AutoFish is active. From then on the mod casts the line, watches the bobber and reels in the catch when a bite happens, then casts again. Pressing O a second time switches it off. Several actions also turn it off automatically, such as swapping to a non-rod item, walking away from the water or opening a screen.
The bite is detected from the bobber's downward velocity, the same signal the vanilla bite animation pulls down on. When that dip is seen, the mod uses the same right-click a player would use, and it pauses briefly before the next cast. It works with the fishing rod, including enchanted variants with Luck of the Sea, and it does not depend on mixins or packet spoofing, because it sends only the actions a human player performs.
Key features
One-key toggle
Pressing O turns the helper on while a rod is in the main hand and off again with the same key.
Bite detection
The bobber's downward velocity signals a bite, and the mod reels in at that moment.
Automatic recast
After each catch a short pause passes and the line is cast again without any player input.
Action bar status
The action bar displays AutoFish while the helper is active, so the state is visible at a glance.

AutoFish is a tiny client-side helper that takes the repetition out of fishing. AutoFish watches the bobber's downward velocity. The vanilla bite animation pulls the bobber straight down for a few ticks; the mod catches that velocity dip, triggers the same right-click your hand would have used, and then waits a short…
