A couple thoughts...

When water temperature drops
fish slow down and hang out. You might want to
find a floating thermometer and
see what your temperature is.

I have a kingfisher that visits my
pond. He can come and go when I'm
gone and I won't see him, except for
the fish he drops. But the fish will
stay spooked for a time after his
visits. All the sign he leaves is a tiny
oil slick and a floating feather ;-)
