The fishermen were arrested by the Maritime Security Agency while they were allegedly fishing in Pakistani waters, the officials said.
They were later sent to a police station in the southern port city of Karachi.
Pakistan and India arrest dozens of fishermen every year for violating the maritime boundary.
Though the two countries have accelerated the process of releasing jailed fishermen, scores continue to be held in prisons in both countries.
On September 11, Pakistan freed 48 Indian fishermen as a goodwill gesture.
