When you try to catch some mob with the hook it will seem like just hitting the mob and the hook will fall to the ground, But the mob is caught with the hook even if it is on the ground, and you can pull the mob with the fishing rod
I don't know if you will undertand because i used the traslator (in some parts), anyways here's a link to a video, showing the issue xd https://youtu.be/yRl2zNaF0hA
