I think the barbels will grow back.
Damaged Catfish Barbels/Whiskers - will they grow back?
(Friend of Bill W., One day at a time)
It depends on how deep the damage goes, and how quickly the issue is dealt with. Lingering bacterial infection means less likely regrowth, same as with too deep of damage where the whole barbel is gone. It is situational of course though.
