Fisheries Department officials told this to reporters.
Rambhai Vala had been arrested in November 2011 by Pakistan Maritime Security Agency for allegedly entering Pakistani waters.
Vala was kept in Karachi jail and breathed his last in a civil hospital in Karachi on May 28.
"The body of the deceased has been handed over to his family members in Una town, where the final rites would be performed," an official said.
Vala's body was flown to Mumbai from Karachi last night, from where it was taken to Junagadh by road, they said.
