5 years sago we had a problem with our carp and quite a few perished after developing sores etc. On EA advice we ceased fishing for a number of months as stress to the fish was believed to be a factor. Subsequently when we started fishing again some fish had minor sores. It was most practical to attend to those at the weigh in when we sprayed them with MelaFix. This seemed to do the trick.I wondered at the time if a cream may have been even more effective.
