Whilst re-freezing previously frozen food is generally not advised, if it's fish that was previously frozen and is being sold as "fresh" fish in a shop, the fish will have been defrosted using a well-controlled method which allows it to be safely re-frozen. The thawing method leaves the previously forzen fish in the same condition as fresh fish.
