Usually means a predator has visited your pond.
Raccoons leave a bit of a mess behind.
Kingfishers will leave a bit of an oil slick and maybe a feather or two, herons
seldom leave any trace except for spooked fish.

General overall predator deterrents:

Heron, kingfisher bird tips:
- netting over the pond
- chimney flue in the bottom of the pond, for fish to hide after the intial
strike
- electric shock pond fence (lays over the water) or electric shock fido fence
- motion activated sprinkler
- plastic fish decoy, called a heron scarer
- (P.S. Migratory Bird Act and Birds of Prey Act forbids lethal methods,
heavy fines and jail time take away from pond
dollars and pond time ;-)

Raccoon tips:
~ electric fido shock fence or pond fence.
~ motion activated sprinkler
~ Call animal control and ask if they have a Hav-a-Hart
humane animal trap to borrow or rent
