Can frozen cod be just as good as fresh?

November 7, 2017: The FoodIngredientsFirst:

"New research reveals that frozen cod can be just as good as fresh, as long as it is handled properly. On average it takes three days for a fresh cod to reach most sales counters. And for both retailers and customers, a three-day-old fresh fish is stretching it a bit. However, if the fish is frozen on board the vessel and thawed properly before it reaches the sales counter, its quality can be just as good as if it had never seen the inside of a freezer. "
The following factors should be done for an optimal product:

• "Firstly, the fish must be frozen as soon as they are hauled on board the fishing boat. In other words, they must be frozen on the vessel before rigor mortis sets in."
• "The fish must then remain frozen at a stable and low temperature for the entire time leading up to thawing. There can be no interruptions in what researchers call the 'cooling chain.'"
• "Thawing itself must then take place immediately before the fish are put on sale, and carried out in water under controlled conditions. If air bubbles are added to the water, the quality of the cod will be even better."
  
  Researchers now recommend that fish should not be thawed for longer than 28 hours at 10 degrees C..
