@headword @misty @CyReVolt good point! But this fish looks more like a 'generic' fish, posibly one of the Cypriniformes. It is just depiced in the air insted of the water. Flying Fish have elongated pectoral fins that act as wings. This fish apparently does not have such fins.

@Jeroen89 is it ai generated picture? It contains a strange mixture of european and north american species, which may be typical nowadays, but not in 1800.
