THE SHORT ANSWER

Is frozen shrimp better than fresh shrimp?

Frozen shrimp can be excellent, and sometimes a better choice than counter shrimp that was previously frozen. What matters most is freezing and handling history.

Moderate confidence

Freezing quality and handling history matter more than the word fresh alone.

The science in more detail

Freezing rate sets ice crystal size and time through the -1C to -5C damage band. Recrystallisation and repeated freeze-thaw cycles increase tissue damage and drip loss.

Faster is not monotonically better; excessively low liquid-nitrogen temperatures can also harm muscle quality. No head-to-head peer-reviewed block-frozen versus IQF shrimp trial was found.
