Could be parasitic , bacterial, or viral although the latter is least likely unless you recently brought in fish from another location. If it's just a few fish out of the entire amount of fish you caught I would not worry about it. Most likely you can't do anything about it anyway.
Any reason why your fish would be stressed at this time? Rapid temp changes, excessive handling, too many fish etc.?
