Will Fish evolve to not bite hooks?
gpt
Obviously the fish doesn't think it is a hook (/bait) but an insect, small fish or whatever (depending on the species).

For fish to evolve to avoid biting hooks they must 

* be able to distinguish between the bait and a real/normal source of food

and/or

* have an alternative food source (avoiding the bait-like-looking food)

(and possibly)

* a large enough portion of the fish must be caught in order to have sufficient evolutionary pressure (or the fish is simply fitter because of other genetic reasons).
