The Indian fishermen were arrested by the Maritime Security Agency (MSA) while they were fishing in Pakistani waters of the Arabian Sea, a spokesman for the Pakistan's Maritime Security Agency (PMSA) told reporters.
The four boats of the fishermen were also seized.
"The fishermen have been handed over to the Docks police for further legal process," he said.
The arrests come just a week after the PMSA arrested 88 Indian fishermen and seized their 16 boats.
Pakistan and India regularly arrest fishermen who venture into each other's waters due to poorly marked maritime boundary.
Some of them spend years behind bars before being repatriated.
In the past, the two nations have released the fishermen as goodwill gestures.
