During depuration, where are shellfish moved?

During depuration, where are shellfish moved?

• A. Deep sea nets with contaminated water
• B. Onshore boiling tanks
• C. Mobile tanks with polluted water
• D. Shoreline tanks circulating water known to be free of contamination

Answer: (D)

Depuration relies on exposing shellfish to clean, circulating water so they purge contaminants without being re-exposed. Moving them to shoreline tanks where water is continuously circulated and known to be free of contamination provides a controlled, sanitary environment for this purification, allowing microbes and other contaminants to decrease over time. Water that’s contaminated or processes that kill shellfish (like boiling) do not achieve depuration, and using mobile tanks with polluted water would reintroduce contaminants. So the best approach is shoreline tanks with circulating clean water.
