Well, can you find a workable (mechanically) material that has the tensile strength of steel? I have caught thrashing, flailing salmon several pounds in weight on size 20 and smaller hooks that are so tiny they are hard to attach to a leader. That's pretty impressive strength for such a tiny object.
I'm sure that something marginally workable could be developed, but I really don't see a reason for it. Fish don't have incredibly keen eyesight to start with. It's far simpler to just continue imbedding the hooks in bait or lures. It's worked pretty well for a few thousand years.
