Reports suggested that Surjeet Singh, currently held at Kot Lakhpat Jail in Lahore, was expected to be freed along with the fishermen but there was no official word in this regard.
Talking to reporters in Islamabad, Rehman Malik, the head of the interior ministry, said Pakistan is taking steps to free Indian fishermen arrested for straying across the maritime boundary without conducting any trial.
Officials said about 130 Indian fishermen are still in Malir jail in Karachi.
Pakistan and India arrest scores of fishermen every year on charges of violating territorial waters. "By releasing the fishermen, Pakistan intended on maintaining friendlier ties with India. We hope India will soon release Pakistani fishermen as well," said Sindh Minister for Law and Prisons Ayaz Soomro.
The two countries have released scores of prisoners, a majority of them fishermen, since they resumed their peace process last year after a gap of over two years in the wake of the 2008 Mumbai terror attacks.
The two sides are working on an arrangement for the speedy repatriation of fishermen detained for inadvertently crossing the maritime boundary.
