This way you are left with the worms and the soil decays.
How to fish quick: Make 2 beacons, spawn 2 account, give 5 survival from random discoveries from trees and such, give equipment that buffs +5 survival and then you buy fishing skill, hearth magic, & you have free experience to use the fishers song which makes it atleast 5x quicker and you dont use XP from useful accounts. Can kill char to do this over and over. Also make use of the cupboard setup for convenient fishing.
Also equip 2 fishing poles so it continues when 1 breaks. (With either line or hook breaking it stops I forget which one, but one of them will not cause the fishing action to stop if you another fully equipped fishing pole.)

To make it a bit more relaxing can also make 1 fish slow and 1 use the buff, because if both buffed then you might be too slow to keep repairing fish pole all the time etc.
