My advice when dealing with fresh fish products, buy fresh, freeze for 48 hrs at 0F (-18C) to destroy any potential parasites, and use up within 30 days or so.
The USDA as well as most state health departments have outlined what they feel is the "best" way to unthaw fresh fish products. You can find those methods in the link below.
