Ive seen no evidence to convince me it does any good on hook holds.
Iv'e seen carp with infections because of hooks left in mouths and damaged mouths. but none definately from removed hooks.
Ok you could say it doesn't do any harm. But do we know that.
Iv'e no confidence in the liquid preparations I'm sure they're washed away in seconds. Gel preparations may be more effective particularly on open sores on the main body of the fish.
My personal view is leave well alone, we're interfeering in a healing process in a creature that lives in a medium completely different from ours and trying to treat them with preparations not designed for them or their environment.
