Redfishman,
What do the "cuts" look like specifically? If they look like jab wounds you are looking at a Great Blue Heron that is jabbing your fish when they are in shallow water. Your fish can be expecially vunerable during spawning time.
I can tell you from experience Herons will jab a fish much to big to eat. I guess it's a natural reflex for them to jab anything that moves regardless of the size.
I have mostly eliminated this problem by running brightly colored catfish line in several strands about a foot over the waters edge where they wade in. I did have one last year that switched to fishing off of my pier, but he's not here anymore this year. I really don't know what happened to him!
