We've searched and although it doesn't seem to exist - so far - can we suggest 'cygnophobia', from the latin cygnus for swan?
Good luck

While I'm sure cygnophobia would be acceptable, phobia etymology is derived from Greek roots, and therefore kiknophobia (from kiknos) would probably be more accurate.
Kiknophobia κύκνος (kiknos)
