Pakistan had last month announced it would release all jailed Indian fishermen as a goodwill gesture during External Affairs Minister S M Krishna's visit to Islamabad for talks with Foreign Minister Hina Rabbani Khar.
The MSA frequently arrests Indian fishermen on charges of violating the country's exclusive economic zone.
The fishermen sometimes languish in jail for months even after completing their prison terms.
After the two countries revived their peace process last year after a gap of over two years in the wake of the 2008 Mumbai attacks, they took several steps to speed up the release of fishermen.
