Yes I did mean that, the problem that arises when doing late night analysis and writing out responses here ...
Wetting your hands does certainly help a lot. But the oils from your skin still do some damage. If a fish is in good health it likely won't be an issue, but it will still cause problems. I use my hands all the time to transfer when my fish are under anaesthesia, but I do wear nitrile gloves, as hands don't do as much damage as an abrasive net. But you are still going to strip some away, but the damage done comes down to the health of the fish.
