Years ago I lived near a large, shallow and very clear park lake with apparently no fish living in it but a group of twenty or so carp of various sizes and a solitary goldfish.
I used to walk my dogs around this lake every single day and try to work out where they'd be under any given weather conditions. I was usually wrong! Every now and then I'd fish for them and if I was stealthy, even catch one or two.
One morning I found the fish in the very deepest part of the lake, down by the dam, a place they very rarely visited in the summer, and there observed the most extraordinary behaviour. All the carp were rising and falling through the water, from lake bed to surface, up and down, up and down, all morning long. This was extraordinary enough but what was quite unbelievable was the manner of this rising and falling motion.
Imagine the fish rising vertically from the bed and as they rise, spiralling around their own axis, like dancers performing pirouettes, and then when they reach the surface flipping over backward and falling back to the bed and repeating the whole movement over and over again.
To this day I have no idea what they were doing. I thought someone here just might have a clue...?
