Thanks Dave! I will say that during the summer months I might find as many as 5 leeches in a LMB's mouth, 2 or 3 is more the norm, but the vast majority of the year the leeches are not present on the fish I catch. There is about a 6-8 week period where the leeches are very prevelant on the fish in our pond every summer. Once they start to disappear the sores in their mouths heal rather quickly. The picture I posted is one I took in Febuary and it is one I the very few times I have seen leeches attached during the cold water months.
