SB 8.24.23
ity uktah so ’nayan matsyam
tatra tatravidasini
jalasaye ’sammitam tam
samudre praksipaj jhasam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
When thus requested, King Satyavrata took the fish to the largest reservoir of water. But when that also proved insufficient, the King at last threw the gigantic fish into the ocean.
