Mending fishing in 1.16.4?

I have a fishing warm in minecraft and wonder if I can fish in 1.16.4 mending books.

Yes you can. But that takes much longer than negotiating.

Thanks for the answer and I know it's very rare but I use an afk fish farm for levels anyway would be a cool thing by the way

That has nothing to do with our hobby "fishing in the great outdoors", what's the point here?
