Slokam 2

The matsya avatar of the Paramathma takes the form of a tiny fish shining brightly in the cupped palms of the king Satyavrata. 

Srimad Bhagavatham  Canto 8

King Satyavrata later became the son of the sun-god and was known as Śrāddhadeva. He was established as Manu by the Supreme Personality of Godhead.

SB 8.24 Summary: During the reign of Cākṣuṣa Manu there was a king named Satyavrata, who was a great pious ruler. To save him, the Lord appeared as the fish incarnation for a second time. King Satyavrata later became the son of the sun-god and was known as Śrāddhadeva. He was established as Manu by the Supreme Personality of Godhead. To receive the favor of the Supreme Personality of Godhead, King Satyavrata engaged in the austerity of subsisting only by drinking water.

Satya means truth and vrata means the foregoing of food. Satyavrata would imply that truth would be maintained under all and any circumstance.

Being a pure tapasvi,  Satyavrata, who is the king of Dramila,  was performing tarpanam (or the offering of water to ancestors). Sitting on the banks of the Kritamala river,  King Satyavrata filled the palm of his cupped hand with water. A tiny fish,  shining brightly appeared in his cupped hands. 

That tiny fish is the beginning of the matsya avatar of the Paramathma. King Sayavrata does not know the identity of the fish at this point. The Paramathma appears in many forms, shapes and sizes to all of us every instant of our lives.  Unlike Prahalada, we do not have the gnanam to see Him everywhere. 

May we dedicate our awareness of this universe unequivocally to the Paramathma.
