Translation:
In His appearance as a fish, the Lord protected Satyavrata Manu, the earth and her valuable herbs. He protected them from the waters of annihilation. As a boar, the Lord killed Hiraṇyākṣa, the son of Diti, while delivering the earth from the universal waters. And as a tortoise, He lifted Mandara Mountain on His back so that nectar could be churned from the ocean. The Lord saved the surrendered king of the elephants, Gajendra, who was suffering terrible distress from the grips of a crocodile.
