You're unlikely to eat them. You can see them quite easily on a

indeed until recently were seen as a good sign, as they drop off fairly
soon after a fish reaches fresh water, and if you saw a few on a fish
you knew it was fresh - in other words had only very recently entered a
river system.

Sea lice are a freaking badge of honor. :-)

Seriously, salmon fishermen look for sea lice on their fish. If they
find them they're very happy.
