Avataars of Lord Vishnu
All the oceans had unified into a single ocean in the Manvantara of Chakshusha . Lord Vishnu in his 11th incarnation as a Matsya (Fish) rescued the earth from Maya the demon. He gave discourses to Satyavrat along with the seven sages, while they were sitting on the boat. He also showed them his illusionary powers. This was his eleventh incarnation.
