You really need to know about fish hook removal, as its very easy to get a hook embedded in your finger, even if theres no fish involved.
But if it's deeply embedded, you're unlikely to be able to remove it on your own - you'll need help.
If it's the latter, be brave ...
The risk of needing either of these fish hook removal methods is much reduced by protecting the hook points whenever its practical ...
Dont try to remove a lure from a large fish before its properly subdued, and even then use long-handled pliers or a proprietary hook extractor designed for the purpose. If, despite these precautions, you or a fellow angler is unlucky enough to get impaled on a hook, one of the following fish hook removal methods will get it out:~
First, clean around the point of entry with antiseptic ointment. If the hook has gone in in such a way that the point is close to the skin, you should consider the push and cut method:~
A disadvantage of the Push and Cut method is that its quite painful and creates a further wound. A less painful alternative, and the one to use where the hook point has not gone in so far is the snatch method:~
Whichever method you use, always wash the wound thoroughly, apply antiseptic ointment and a simple dressing.
Check that your tetanus shots are up to date, and if not, attend to it at the earliest opportunity.
Be particularly careful when removing a multi-hooked lure ...
I met a French sailboat skipper in Martinique who, while attempting to remove a treble hook from his crews hand, managed to impale his own finger on a second treble on the same lure. Being in mid-Atlantic at the time, the prospect of sharing each other's intimate moments for 1,500 miles was a depressing prospect.
Next time, he told me, he would either remove, cut off the points, or tape up all other hooks before attempting first aid. Good advice!
And one final piece of advice ...
Always wear some form of eye protection - spectacles or sunglasses at least - when using the snatch method.
