A friend of mine has a fishpond & a couple of times a week he finds

Any idea what sort of predator he should be looking for? We assumed
that anything that would get the fish out of the pond would eat the
whole fish (e.g. heron or cat)

Thanks

A cat is what first comes to mind. However, it depends on your local area to
some extent..........town/country etc.

and add some more local area detail. You'll also get good advice as to how
your beighbour can protect his pond from predators.
