True story... My house backs onto a man-made storm drain lake, and there used to be goldfish in the lake for several years. One year, I was looking out the window eating lunch, and an osprey was circling the lake. To my surprise it dove and caught a 10 inch, bright orange, goldfish! Took off to it's nest. He was back everyday, and my ex-neighbour actually had a telephoto lens on his DSLR and had photos of the goldfish in its talons. Unfortunately I don't have a photo. So I mean it's not significant, but some creatures prey on the carp.
The next year I was walking the shoreline and came across a 13" goldfish dead on shore.
