These carp are using aquatic surface respiration to get oxygen for their systems.  During summer water oxygen levels can drop, and fish will resort to breathing in the water which is in direct contact with the air. The layer of water in contact with air has higher levels of oxygen.

 

The carp were also in the vicinity of a small waterfall flowing off a spillway, which would also help increase oxygenation of the water.
