Do you have a friend in your realm,server or on your world that keeps on fishing?
When you ask them to stop fishing and go to do exploring, adventuring or even caving, and they clearly say NO! ?
Well if you want them to make not fish,Then use this addon/behaviour pack that is for ios, android and win10 for 1.2+ version
When you apply the addon it will completely stop your friend to catch a fish or maybe some treasure
there will be bubbles but when they will try to catch they will simply miss it and they will thought it is a bug and then they will easily go for exploring like going woodland mansion.
or
you can just simpaly do it for pranking them
